ICAEW chart of the week: UK population projections

The Office for National Statistics has updated its national population projections, lifting its expectations for 2025 by one million to just under 70 million people living in the UK and for 2050 by four million to 78 million.

(c) ICAEW 2024

My chart for ICAEW this week takes the latest principal population projections for the UK published by the Office for National Statistics (ONS) on 30 January 2024 and illustrates how the number of people in the UK has increased since 1975 and is projected to increase to 2075.

According to the ONS, there were 56m people living in the UK in June 1975 and our chart shows how this increased by 2m from births exceeding deaths (18m births – 16m deaths) and by 1m from net inward migration to reach 59m in June 2000, an average annual population growth rate of 0.2%.

The first quarter of the current century is expected to see the population increase to just under 70m by the middle of 2025, from a combination of 3m births less deaths (18m births – 15m deaths) and net inward migration of 8m, an average of just over 300,000 per year. This is equivalent to an average annual population growth rate of 0.7%.

From there, the population is projected to increase by approximately 8m to 78m in 2050, an average annual growth rate of 0.4%. This is driven by an assumption that immigration will continue to exceed emigration in the long-term by 315,000 a year, contributing 8m to the increase, while projected deaths are expected to marginally exceed births (18m deaths – 18m births) over the same period. The latter is also affected by the assumed level of immigration, with the ONS estimating that if net migration was zero then the population would fall by 3m over the 25 years to 2050 (18m deaths – 15m births).

The chart concludes with the projection for the following quarter-century from 2050 to 2075, with deaths exceeding births by 3m (21m deaths – 18m births) to partially offset an 8m projected increase from net inward migration to reach 83m in 2075, an average annual population growth of 0.3%.

These numbers are higher than the previous projection published by the ONS in January 2023 by 1m in 2025, 4m in 2050 and 8m in 2075, partly as a consequence of updating the baseline numbers to reflect the 2021 Census, but mainly because of higher assumptions for net inward migration. The ONS doubled the expected number of net inward migrants over the three years to June 2025 from approximately 300,000 per year to around 600,000 per year, and increased its long-term assumption from 245,000 net inward migrants per year to 315,000.

The challenge for policymakers is in balancing the needs of the economy and the public finances for more workers in order to pay for the pensions and health care costs of a rapidly growing number of pensioners, and fee-paying international students to subsidise the domestic university system, with political pressures to control immigration. Perhaps unsurprisingly this had led to a degree of unpredictability in immigration policy.

The challenge for the ONS is trying to reflect in its projections a highly unpredictable immigration policy, which in this case has resulted in it increasing its assumptions for net inward migration just as the government introduces a series of new restrictions that should significantly reduce the incoming flow of migrants. 

The irony is that the ONS might have been better off just leaving its previous projections in place – but then that’s life in the forecasting game.

ICAEW chart of the week: Pensioners dilemma

The ‘elephant in the room’ of growing numbers of pensioners and what that will mean for the long-term prospects of the public finances is likely to be avoided yet again at next week’s Autumn Statement.

My chart for ICAEW this week is on the ‘elephant in the room’ that haunts fiscal events such as next week’s Autumn Statement – the rapidly rising number of pensioners that is driving some of the biggest line items in the national budget: pensions, health and social care.

This fiscal event is unlikely to be any different, with the Chancellor expected to focus most of his statement on short-term measures to free up headroom for pre-election tax cuts at a time of stagnant economic growth.

Any substantive discussion on the long-term prospects for the public finances is likely to be absent beyond a continued commitment to seeing the debt to GDP ratio start to fall within the next five years. How he – or more likely his successors – might be able to avoid having to raise taxes significantly in the coming decades to pay for the cost of pensions, health and social care for many more people, living longer, sometimes less healthy lives, is unlikely to be at the core of what is announced.

To illustrate the dilemma facing policymakers and the public, our chart shows how pensioners represent 3.3m out of the 4.0m projected increase in the size of the UK population between 2023 and 2043. The total population of the UK is projected to increase by 6% from 68.1m in 2023 to 72.1m in 2043, with the number of pensioners expected to increase by 27% from 12.4m this year to 15.7m in 20 years’ time. 

The number of non-pensioners is expected to increase by 0.7m or 1% from 55.7m to 56.4m, with net inward migration of 5.0m over that period offsetting what would otherwise be a significant fall in the numbers below retirement age. (Not shown in the chart is a projected 3% rise in the working age population and a 7% fall in the number of children.)

The projected 27% rise in the number of pensioners is despite a planned increase in the state pension age from age 66 to age 67 in 2027, one of the few long-term steps the government has taken to mitigate the fiscal effects of rising pensioner numbers. However, increasing the retirement age doesn’t directly impact health and social care costs, as well as being partly offset by the cost of supporting increasing numbers of people out of work between traditional retirement age and the age at which they can take their state pension.

Given the significance of the demographic challenge to the public finances, there is very little public debate on what to do, especially as the current policy of cutting the proportion of spending going on public services outside of health appears increasingly unsustainable. 

Spending on defence and security (the traditional budget to raid) is already close to the NATO minimum and appears likely to need to increase given the global security situation, while extracting further savings from other public services seems extremely unlikely, especially given the reluctance of successive governments to put in the level of upfront and ongoing capital investment that might make operational savings possible.

The irony is that, unlike the game-theory scenario of the prisoners’ dilemma that makes optimal decision-making difficult for two prisoners who can’t communicate with each other, there is no theoretical restriction on the ability of policymakers to talk to the public about the pensioners dilemma and to have a proper debate about that might mean for taxes and public services in the long term.

ICAEW chart of the week: Japan demographics

We look at how Japan’s population is ageing and falling fast, presenting some major challenges for the public finances of the third largest national economy in the world.

Column chart showing Japan's population at twenty-year intervals from 1963 to 2063, analysed into five age groups: Ages 0-19, Ages 20-39, Ages 40-59, Ages 60-79, Ages 80+.

1963 – 36m, 32m, 19m, 8m and 1m – 96m total
1983 – 35m, 36m, 31m, 15m and 2m – 119m total
2003 – 25m, 35m, 35m, 27m and 5m – 127m total
2023 – 20m, 26m, 35m, 31m and 12m – 124m total
2043 – 15m, 22m, 26m, 31m and 16m – 110m total
2063 – 12m, 17m, 22m, 24m and 18m – 93m total

Our chart this week is on the demographics of Japan, looking at how its population grew rapidly from 96m in 1963 to 119m in 1983 and then 127m in 2003, before falling to 124m this year, to a projected 110m in 20 years’ time, and to 93m in 40 years’ time.

Our analysis starts with the 96m people who lived in Japan in 1963 and shows how increased longevity saw the population increase to 119m in 1983 (an increase of 24m from 36m births and 2m migrants less 14m deaths), before increasing to 127m in 2003 (a further 8m increase from 25m births less 17m deaths). 

The population has been relatively stable since then, peaking at 128m in 2010 (not shown in the chart), before dropping to 124m this year as the number of births (20m over the last 20 years) fell below the number of deaths (25m). This was offset by a small amount of net inward migration, with the non-Japanese component of the population amounting to 3m in 2023.

Fewer younger people means that the number of births is expected to be even smaller over the next 20 years to 2043 at around 15m, at the same time as deaths are expected to increase in line with an older population. According to the latest medium-variant projections of Japan’s National Institute of Population and Social Security Research, the population is projected to drop by 14m to 110m in 2043 (15m births + 3m migrants – 32m deaths) before falling by a further 17m to 93m in 2063 (12m births + 3m migrants – 32m deaths).

The primary purpose of the chart is to illustrate how the age profile has shifted and continues to change as Japan gets older. Grouped into five age segments: 0-19, 20-39, 40-59, 60-79 and 80+, the population was, is, and is projected to be as follows:

1963 – 36m, 32m, 19m, 8m and 1m – 96m total
1983 – 35m, 36m, 31m, 15m and 2m – 119m total
2003 – 25m, 35m, 35m, 27m and 5m – 127m total
2023 – 20m, 26m, 35m, 31m and 12m – 124m total
2043 – 15m, 22m, 26m, 31m and 16m – 110m total
2063 – 12m, 17m, 22m, 24m and 18m – 93m total

The contrast in the age profile in the 20th century compared with 21st century Japan is dramatic, with the proportion of population aged 60 or over increasing from 9% in 1963 to 35% today and to a projected 45% in 2063, at the same time as the share aged under 40 has fallen from 72% in 1963 to 37% in 2023 and to a projected 31% in 2063.

Also not shown in the chart is Japan’s median age, which was 26 in 1963, 33 in 1983, 42 in 2003 and 49 this year, before being projected to reach 53 in 2043 and 56 in 2063 – more than double that of a century earlier.

These demographic shifts have and will continue to present a major fiscal challenge for the Japanese government. The continued growth in size of older generations (who typically consume the most in public services and welfare), accompanied by a shrinking working-age population (the group that typically pays most of the taxes that fund public services and welfare), will not be an easy dynamic to manage. At the same time, Japan already has one of the largest national debts of any country at in excess of 250% of its GDP.

One action Japan could take is to increase the pace of net inward migration even more than it already has, given it is currently at a much lower level than in many other developed countries such as the UK. This would have the benefit of bringing in more tax-paying individuals of working age and potentially assist in driving up the birth rate, slowing the rate of fall in the size of the population. However, there would be significant political challenges to overcome for such a route to be successful.

The good news for Japan is that it can still borrow at very low interest rates, with the effective interest rate payable on 10-year government bonds currently at 0.4%, much lower than in many comparable countries with much lower levels of external debt. This is both a threat, in that interest rates could go up significantly in the future, but also an opportunity in that the Japanese government is able to invest in adapting itself for a very different future.

ICAEW chart of the week: Africa

I take a look at Africa this week and how its current population of 1.5bn, 18% of the world’s total, is distributed across the continent.

Map of Africa's 1.5bn people with countries coloured into five regions, overlayed by semi-transparent scaled bubbles with the population of each region.

Teal: Western Africa 435m.
Orange: Northern Africa 221m.
Green: Central Africa 178m.
Purple: Southern Africa 198m.
Blue: Eastern Africa 428m.

My chart this week illustrates how Africa’s population of 1,460m can be divided into five regions. These comprise Western Africa with 435m people, Northern Africa with 221m, Central Africa with 178m, Southern Africa with 198m, and Eastern Africa with 428m. 

These regions are based on the African Union’s official regions for its 55 member states, which differ from the regions used by the United Nations. They include Réunion (1.0m) and Mayotte (0.3m), two French overseas territories in the Indian Ocean that are not members of the African Union, as well as St Helena (5,000), an overseas territory of the UK in the Atlantic. It also includes an estimated 5.8m people living in African Union applicant Somaliland that are included within the number for Somalia.

Excluded are 175,000 or so people living on the African continent in Ceuta and Melilla (Spain), around 2.2m and 250,000 respectively in the Atlantic Ocean on the Canary Islands (Spain) and Madeira (Portugal), and several hundred people in the Indian Ocean within France’s Southern Territories.

The table below breaks down the total by country within each region, highlighting how the four largest countries by population each have more than 100m people, led by Nigeria with 223.8m (15.3% of Africa’s total), Ethiopia with 126.5m (8.7%), Egypt with 112.7m (7.7%) and the Democratic Republic of the Congo with 102.3m (7.0%). 

The next largest are Tanzania with 67.4m (4.6%), South Africa with 60.4m (4.1%), Kenya with 55.1m (3.8%), Uganda with 48.6m (3.3%), Sudan with 48.1m (3.3%), Algeria with 45.6m (3.1%), Morocco with 37.8m (2.6%), Angola with 36.7m (2.5%), Ghana with 34.1m (2.3%), Mozambique with 33.9m (2.3%), Madagascar with 30.3m (2.1%) and Côte d’Ivoire with 28.9m (2.0%).

Table showing populations by each region:

Western Africa 435m: Nigeria 223.8m, Ghana 34.1m, Côte d'Ivoire 28.9m, Niger 27.2m, Mali 23.3m, Burkina Faso 23.3m, Senegal 17.7m, Guinea 14.2m, Benin 13.7m, Togo 9.1m, Sierra Leone 8.9m, Liberia 5.4m, Gambia 2.8m, Guinea-Bissau 2.2m, Cabo Verde 0.6m, St Helena (UK) 0.0m.

Northern Africa 221m: Egypt 112.7m, Algeria 45.6m, Morocco 37.8m, Tunisia 12.5m, Libya 6.9m, Mauritania 4.9m, Western Sahara 0.6m.

Central Africa 178m: DR Congo 102.3m, Cameroon 28.6m, Chad 13.2m, Congo 6.1m, Central African Republic 5.7m, Gabon 2.4m, Equatorial Guinea 1.7m, São Tomé and Principe 0.2m.

Southern Africa 198m: South Africa 60.4m, Angola 36.7m, Mozambique 33.9m, Malawi 20.9m, Zambia 20.6m, Zimbabwe 16.7m, Botswana 2.7m, Namibia 2.6m, Lesotho 2.3m, Eswatini 1.2m.

Eastern Africa 428m: Ethiopia 126.5m, Tanzania 67.4m, Kenya 55.1m, Uganda 48.6m, Sudan 48.1m, Madagascar 30.3m, Somalia 18.1m, Rwanda 14.1m, South Sudan 11.1m, Eritrea 3.7m, Mauritius 1.3m, Djibouti 1.1m, Réunion (FR) 1.0m, Comoros 0.9m, Mayotte (FR) 0.3m, Seychelles 0.1m.

The population of Africa is expected to grow significantly over the rest of the century, with the UN’s medium variant projecting a population of 1.7bn (20% of the projected global total) in 2030, 2.1bn in 2040 (23%), 2.5bn (26%) in 2050, 2.9bn (28%) in 2060, 3.2bn (31%) in 2070, 3.5bn (34%) in 2080, 3.7bn (36%) in 2090 and 3.9bn (38%) in 2100. This is despite a rapidly declining birth rate, with many more Africans living much longer lives than preceding generations.

Africa is currently relatively poor compared with advanced economies, with the total GDP for its 55 countries and 1.5bn people close in size to the UK’s single country GDP for 67.5m people of around £2.5trn a year at current exchange rates. This is around 3% of the global economy in each case. 

The UK’s share of the global economy is likely to decline over the rest of the century as Africa and other developing economies grow at a much faster pace. For Africa the combination of a rapidly growing population and economic development should see it become substantially more significant to the global economy than it is today.

ICAEW chart of the week: China population

Our chart this week follows the news that China’s population has peaked at just over 1.4bn, illustrating the dramatic change that has taken place over the last 40 years.

Step chart showing the change between China's population in 1981 and 2021.

997m in 1981, comprising 765m age 0-39, 228m age 40-79 and 4m age 80+.

+776m births
- 332m deaths
- 15m net migration

= 1,426m in 2021 comprising 735m age 0-39, 658m age 40-79 and 33m age 80+.

The news that China’s population has peaked and is starting to fall prompted us to take a look at how the country with the largest population in the world has changed over the last 40 years.

In 1981, two years after the introduction of the one-child policy, China was a young country, with a population of 997m and a median age of 21. Today it is a mature country, with a population of 1,426m and a median age of 38, approaching that of many western countries.

Our chart shows how that population has changed according to the United Nations Population Division. In July 1981, China was estimated to amount to 997m, comprising 765m under the age 40, 228m between the ages of 40 and 79, and 4m aged 80 or over. Since then, there have been 776m births, 332m deaths and net outward migration of 15m to reach a total of 1,426m in July 2021. This comprised 735m people aged between 0 and 39, 658m between 40 and 79 and 33m aged 80 or over.

The dramatic change in the age profile reflects the huge success that China has had in tackling poverty and disease, enabling many more children to survive into adulthood compared with previous generations, and to then live longer lives. Infant mortality fell from 45 per thousand births in 1981 to less than six per thousand in 2021 and life expectancy at birth increased from 65 to 78.

The rapid growth in the population over the last 40 years has slowed in recent years as the number of births has fallen and (as the population has aged) deaths have increased. There were 10.9m births in 2021 (down from 12.2m in 2020, much less than the 22.8m births in 1981) and 10.6m deaths (up from 10.3m in 2020 and much higher than the 7.4m deaths recorded in 1981). With net outward migration of 0.2m, the net increase in the population in 2021 was less than 0.1m, down from the net increase of 1.9m in 2021 and much lower than the 17.1m increase experienced in 1982 and the peak increase of 19.9m in 1990.

According to the UN’s numbers, China’s population was expected to peak this year (in 2023), with a central projection that would see the population falling by 233m the next 40 years to 1,193m in 2061, and then to 767m in 2100.

However, China’s population is now believed to have peaked already, with the National Bureau of Statistics of China announcing on 17 January 2023 that China’s population excluding foreign citizens and excluding Hong Kong, Macau and Taiwan fell by 0.85m from 1,412.6m in December 2021 to 1,411.75m at the end of 2022.

India, with an estimated population of 1,407m in July 2021 according to the UN, was expected to overtake China as the world’s largest population during 2023, but there is some speculation following China’s announcement that this has already occurred. India’s population is currently projected to continue to grow over the next 40 years and peak at 1,697m in 2064.

With the population peaking and many more people living longer lives, the fiscal challenge facing China becomes similar to those facing western nations: how to support a rapidly increasing number of pensioners at the same time as the working age population is declining.

ICAEW chart of the week: England and Wales Census 2021

The ICAEW chart of the week looks at the results of last year’s census, illustrating how the population of southern and central England has grown much faster than in the north of England and in Wales over the past decade.

Bubble chart overlayed on a map of England & Wales scaled to population in each region with inner bubbles showing the increase in the last decade. 

North East 2.6m (+1.9%)
North West 7.4m (+5.2%)
Yorkshire 5.5m (+3.7%)

West Midlands 6.0m (+6.2%)
East Midlands 4.9m (+7.7%)
East of England 6.3m (+8.3%)

South West 5.7m (+7.8%)
South East 9.3m (+7.5%)
London 8.8m (+7.7%)

Wales 3.1m (+1.4%)

The Office for National Statistics (ONS) released the first results from Census 2021 in England and Wales on Tuesday 28 June, providing an initial snapshot of who we are and where we live across two of the four nations of the UK. It follows on from the initial release earlier this year of the Northern Ireland Census 2021, but we won’t see a full picture for the UK for some time as the 2022 census in Scotland was delayed until this year.

The chart highlights how the East of England was the fastest growing region in England, with its population growing by 8.3% to 6.3m between 2011 and 2021. This was followed by the South West (up 7.8% to 5.7m), London (up 7.7% to 8.8m), East Midlands (up 7.7% to 4.9m) and the South East (up 7.5% to 9.3m). The West Midlands grew less quickly (up 6.2% to 6.0m), but still by more than the North West (up 5.2% to 7.4m), Yorkshire (up 3.7% to 5.5m) and the North East (up 1.9% to 2.6m). The population of Wales only increased by 1.4% over 10 years to remain at 3.1m.

In total the population of England and Wales amounted to 59.6m in 2021. This was 6.3% higher than the 56.1m people living in the UK in 2011 and 14.6% higher than the 52.0m reported by the 2001 census. This reflects a slowing rate of growth in the last decade at 0.6% a year on average compared with the average rate of 0.8% seen between 2001 and 2011 and is substantially lower than the compound growth of 1.6% a year experienced over 120 years since the first official census in 1801 reported a population of 8.9m in England & Wales.

The ONS has published a breakdown of the population by age and sex by local authority, highlighting how the number of people has changed significantly in some parts of the country, such as Tower Hamlets (up 22% in 10 years), Dartford (up 20%), Barking and Dagenham (up 18%), Bedford (up 18%), Peterborough (up 17.5%), Central Bedfordshire and Tewkesbury (each up 16%) and Salford, Milton Keynes, Uttlesford, Vale of White Horse and Wokingham (each up by around 15%). The biggest falls were in Kensington and Chelsea (down 10%) and Westminster (down 7%), although there is some speculation that this was because of the pandemic as family and second homes elsewhere proved to be more attractive places to work from home during lockdown. This is unlikely to be the driver of decreases in some rural areas such as the 6% fall in Ceredigion in Wales or the 5% fall in Copeland in Cumbria, where long-term trends of population decline have continued.

The census has also confirmed how we are getting older on average, with a 20% increase in those aged 65 and over from 9.2m in 2011 to 11.1m in 2021. This continues to be a big driver for public finances, as more funding is needed to pay for pensions, health and social care at the expense of other public services.

There is still a lot of data crunching to do as the statisticians work through the more in-depth questions on the census, ranging from employment status, education and housing to ethnicity, religion, sexual orientation and gender identity among other characteristics – demographics in action and the likely source of future charts of the week.

ICAEW chart of the week: Global population

The ICAEW chart of the week looks at how the estimated global population of almost 8bn people is distributed around the world.

Bubble chart showing estimated global population of 7,995m in 2022: South Asia 1,894m, East Asia 1,671m, South East Asia 682m, Pacific 43m, Africa 1,419, Europe 592m, Middle East 357m, Eurasia 246m, North America 511m, South America 443m and Central America & Caribbean 97m.

UN projections show that the planetary population will reach approximately 7,955m in June this year, a 1.0% increase over the 7,875m estimate for June 2021.

The largest region on our chart is South Asia, which has 1,894m inhabitants, including 1,411m in India, 216m in Pakistan, 173m in Bangladesh, 40m in Afghanistan and 31m in Nepal. This is followed in size by the 1,671m people living in East Asia, including 1,432m in mainland China (currently the most populous country in the world), 126m in Japan, 52m in South Korea and 26m in North Korea.

Africa is the third largest region with 1,419m inhabitants, with 482m living in Eastern Africa (including Ethiopia 118m, Tanzania 67m, Kenya 56m, Uganda 50m, Mozambique 34m and Madagascar 29m), 424m in Western Africa (including Nigeria 217m, Ghana 32m, Côte d’Ivoire 27m and Niger 26m), 254m in Northern Africa (including Egypt 106m, Sudan 46m, Algeria 45m and Morocco 38m), 190m in Middle Africa (including the Democratic Republic of the Congo 95m, Angola 35m and Cameroon 27m), and 69m in Southern Africa (of which 60m are in South Africa).

Excluding Russia and Belarus, Europe has 592m people, including 444m in the 27 countries of the EU (including Germany 83m, France 66m, Italy 59m, Spain 46m and Poland 38m), 68m in the UK and 43m in Ukraine, although these numbers are all before taking account of the several million Ukrainians who have been forced to flee the war and are living temporarily in other countries. 

Eurasia, comprising the Commonwealth of Independent States of Russia, Belarus and the ‘stans’ of central Asia, has 246m inhabitants (including Russia 143m and Uzbekistan 34m), while the Middle East has an estimated 357m people (including Turkey 85m, Iran 85m, Iraq 44m, Saudi Arabia 36m and Yemen 32m.

North America has 511m inhabitants (USA 336m, Mexico 137m, Canada 38m), while 97m live in Central America (52m) and the Caribbean (45m), and 443m live in South America (including Brazil 217m, Colombia 51m, Argentina 46m, Peru 34m and Venezuela 34m).

South East Asia has 682m inhabitants, including 277m in Indonesia, 113m in the Philippines, 100m in Vietnam, 70m in Thailand, 56m in Myanmar and 34m in Malaysia. A further 43m people live in the Pacific region, of which 26m are in Australia. 

Although the rate of global population growth was projected to slow significantly in recent years, from 1.3% a year in 2000 when the population was 6.1bn, to 1.0% a year currently and to a forecast of around 0.7% in 20 years’ time, that still means that the number of people on the planet is expected to grow to around 9.8bn in 2050, placing even greater demands on natural resources than today. 

This highlights just how important achieving net zero and environmental sustainability is to the lives and wellbeing of future generations.

ICAEW chart of the week: UK population projections 2020 to 2045

Our chart this week is based on the latest population projections for the UK, with an expected 67% increase in the number of people over the age of 75 and a fall in the number under the age of 25 over the next quarter of a century.

Chart illustrating how population of 67.1m people in 2020 (19.8m ages 0-24, 21.8m ages 25-49, 19.7m ages 50-74, 5.8m ages 75+) changes over the 25 years with 16.6m births, 18.0m deaths and 5.3m net migrants to get to 71.0m in 2024 (18.0m ages 0-24, 22.4 ages 25-49, 20.9m ages 50-74 and 9.7m ages 75+). For more detail see the text.

The Office for National Statistics (ONS) released 2020-based interim population projections on 12 January 2022 providing an insight into how the population of the UK is expected to change over the next 100 years. They are interim because they don’t include the results of the 2021 Census (which is still being worked on), but they do reflect updated assumptions from the 2018-based projections.

The main differences from the previous projections are a lower fertility rate (revised down from 1.78 to 1.59 per woman) reducing the numbers of births significantly, and slight reductions in anticipated life expectancy (from 82.8 years to 82.2 for males and from 85.7 to 85.3 for females) increasing the number of deaths. This has been partly offset by an increase in net annual long-term international migration from 190,000 a year to 205,000 a year, with a central projection last time of 72.8m people in 2045 revised down to 71.0m. The population is then expected to gradually increase to a peak of 71.8m in 2081, before declining back to 71.0m in 2120.

Our chart focuses on the first 25 years of the projections, illustrating how each generation is expected to change over that time. Overall, the estimated population of 67.1m in June 2020 is expected to change by 16.6m births (an average of around 665,000 a year) less 18.0m deaths (720,000 a year), which would result in a fall of 1.4m (55,000 a year) to 65.7m in 2045, at least before taking into account the effects of migration. Estimated net immigration of 5.3m (230,000 a year until 2026, then 205,000 a year) is expected to mean that the population will instead increase, reaching 71.0m in 2045.

There were an estimated 19.8m 0-24 year-olds in 2020, but in a quarter of a century they will all be in the 25-49 age group and so those under 25 will be formed from the 16.6m projected to be born in the 25 years from 2020, which after around 65,000 deaths would be 16.5m before taking account of migration. Some will leave the country and others will arrive, with a projected 1.5m net addition to take the total to 18.0m in 2045, a reduction of 1.8m compared with the previous cohort.

For the 19.8m under-25s in 2020 moving up a cohort to the 25-49 age group in 2045, deaths of 0.2m would reduce this to 19.6m before taking account of net inward migration of 2.8m to get to a projected 22.4m. This is a net increase of 0.6m compared with the previous generation of 21.8m. That generation, which would be aged 50-74 a quarter of a century later, would be reduced by 1.7m deaths to arrive at 20.1m before adding a net 0.8m from migration to get to 20.9m, a 1.2m increase over the 19.7m who were aged 50-74 in 2020.

A much greater proportion of this cohort will not be around in 2045, with a projected 10.2m deaths reducing numbers to 9.5m before adding 0.2m from net inward migration to arrive at a projected total of 9.7m. This is a 67% increase over the current generation of over-75s of 5.8m, with all bar the 38,000 expected to be over 100 in 2045 expected to have passed on, barring major developments in medical science. This compares with the approximately 15,000 people over the age of 100 in 2020.

Overall the rate of increase in the UK population is expected to fall from an estimated 0.4% a year in 2020 to 0.15% by 2045, an average of 0.2% over the coming quarter of a century. This compares with growth rates of 0.6% to 0.8% a year experienced in the last couple of decades, which has been a key driver of economic growth in that time.

The substantial increase in the numbers aged 75 and over is of course a hugely positive development as more people live much longer lives than in previous generations. However, this will have huge implications for the public finances given the cost implications of providing health services, social care and pensions to older generations, particularly those over the age of 75. With proportionately fewer workers (even with planned increases in the retirement age) this is expected to drive higher levels of taxation over the next quarter of a century without much higher levels of economic growth than are currently anticipated.

Fortunately a quarter of a century provides opportunity for governments to address the financial challenges posed by our success in extending lives if they are willing to do so, even with the added debt arising from the pandemic, which is why ICAEW continues to argue for the development of a long-term fiscal strategy to put the public finances on a sustainable path. Such a strategy could make a significant difference to the prosperity of future generations.

ICAEW chart of the week: Germany

My chart this week is on Germany, where a new ‘traffic light’ coalition government headed by Chancellor-designate Olaf Scholtz is poised to take charge of Europe’s most prosperous nation.

Map of Germany showing population of 83.2m by state or 'bundesländer': Nordrhein-Westfalen (North Rhine Westphalia) 17.9m, Bayern (Bavaria) 13.1m, Baden-Württemberg 11.1m, Niedersachsen (Lower Saxony) 8.0m, Hessen 6.3m, Rheinland-Pfalz (Rhineland Palatinate) 4.1m, Sachsen (Saxony) 4.1m, Berlin 3.7m, Schleswig-Holstein 2.9m, Brandenburg 2.5m, Sachsen-Anhalt (Saxony-Anhalt) 2.2m, Thüringen 2.1m, Hamburg 1.9m, Mecklenburg-Vorpommern 1.6m, Saarland 1.0m and Bremen 0.7m

With a population of 83.2m and a €3.4tn (£2.9tn) economy, Germany is the largest member of the European Union and the fourth biggest national economy in the world after the USA, China and Japan.

The formal agreement of a red-green-yellow ‘traffic light’ coalition between the centre-left Social Democratic Party (SPD), the Green Party and the liberal Free Democratic Party (FDP) means that Angela Merkel can finally retire as Chancellor to be replaced by SPD-leader Olaf Scholz, the current Vice-Chancellor and Finance Minister in the outgoing ‘Grand Coalition’.

According to the coalition agreement, which is still subject to ratification by the three parties, Olaf Scholtz will become the new Chancellor with the SPD filling six of the 15 federal ministries, the Green party filling five ministries and the FDP filling four. Green co-leaders Annalena Baerbock and Robert Habeck are expected to become Foreign Minister and Economy & Climate Change Minister respectively, while FDP leader Christian Lindner is expected to become Finance Minister.

Despite running the most powerful country in Europe, the new coalition is only responsible for the federal government. As the chart illustrates, Germany has sixteen Bundesländer or federal states, comprising Nordrhein-Westfalen (North Rhine Westphalia) with 17.9m people, Bayern (Bavaria) with 13.1m, Baden-Württemberg with 11.1m, Niedersachsen (Lower Saxony) with 8.0m, Hessen with 6.3m, Rheinland-Pfalz (Rhineland Palatinate) and Sachsen (Saxony) each with 4.1m, the city-state of Berlin with 3.7m, Schleswig-Holstein with 2.9m, Brandenburg with 2.5m, Sachsen-Anhalt (Saxony-Anhalt) with 2.2m, Thüringen with 2.1m, the city-state of Hamburg with 1.9m, Mecklenburg-Vorpommern with 1.6m, Saarland with 1.0m and the city-state of Bremen with 0.7m.

The state governments are also run by coalitions. The now federal opposition Union parties (the Christian Democratic Union and the Bavarian Christian Social Union) lead two- or three-party coalitions in seven states, the SPD lead in seven states, the Greens in one state and Der Linke (the Left) in one state. With a proportional voting system at state and federal levels, coalition government is a way of life in Germany, with parties that are in government in one state being in opposition to each other in others.

Despite being the first three-party coalition at a federal level, with the more complicated negotiations that entails, the coalition agreement has been reached fairly ‘speedily’ by German standards – taking just over two months compared with the six months taken to agree the ‘Grand Coalition’ between the Union parties and the SPD following the last election in September 2017.

The inclusion of the Greens puts climate change at the top of the new government’s priorities, bringing forward the end of coal from 2038 to 2030 for example, while the inclusion of the fiscally prudent FDP will mean limited scope for new government borrowing. Other plans include raising the minimum wage, more defence spending, and legalising cannabis,

ICAEW chart of the week: UK population of 67.1m

This week’s chart covers the pre-census population estimate of 67.1m for June 2020 just released by the Office for National Statistics. Do more deaths, fewer births and returning migrants mean the 2021 number will be smaller?

Map of UK with nations and regions in different shades and labels with populations: Scotland 5.5m, North East 2.7m, Yorkshire and the Humber 5.5m, East Midlands 4.8m, East of England 6.3m, London 9.0m, South East 9.2m, South West 5.7m, West Midlands Region 5.9m, Wales 3.2m, North West 7.4m, Northern Ireland 1.9m.

ICAEW’s chart of the week is based on the UK population estimate for June 2020 released by the Office for National Statistics (ONS) on 25 June 2021, which estimates that there were 67.1m people living in the UK last summer. This is the last estimate before the March 2021 census that should provide a more accurate count of the population – potentially leading to revisions to this and previous estimates over the last few years.

The population estimate comprises 56.5m people in England, 5.5m in Scotland, 3.2m in Wales and 1.9m in Northern Ireland. Within England there were 9.0m in London, 9.2m in the South East, 6.3m in the East of England, 4.8m in East Midlands, 5.5m in Yorkshire & the Humber, 2.7m in the North East, 7.4m in North West (including 2.8m in Greater Manchester), 5.9m in the West Midlands (including 2.9m in the West Midlands city-region), and 5.7m in the South West.

The median age for the population was 40.4 years old, with 19.8m aged between 0 and 24, 21.8m from 25 to 49, 19.7m from 50 to 74 and 5.8m aged 75 or more.

The ONS reports that the population increased by 284,000 or 0.43% from 2019 comprising a ‘natural’ increase of 32,000 (701,000 births less 669,000 deaths), net migration of 247,000 (immigration of 622,000 less emigration 375,000) and other movements of 5,000. This is a fall from the 361,000 increase seen in the previous year, primarily because of the coronavirus pandemic from mid-March 2020 to June 2020, when deaths increased and migration went into reverse.

The big question is whether the population may actually shrink when the 2021 census is reported, with deaths from the second and third waves of the pandemic, a further decline in the birth rate and a potential outflow of migrants combining to reduce the population for the first time since 1982.
