Scotland’s population has risen to 5,436,600 – the highest figure on record – the first results from the 2022 census have shown.
It grew by 141,200 (2.7%) since 2011 – a slower rate of growth than the last census and the slowest rate in the UK.
The National Records of Scotland (NRS) data shows that without migration the population would have decreased by about 49,800 since 2011.
More than one million people are aged 65 and over – a 22.5% rise since 2011.
The census is usually carried out every 10 years and asks people to answer questions about themselves, their household and their home to build a detailed snapshot of society.
The results are intended to help organisations make decisions on planning and funding public services such as transport, education and healthcare.
While it is the highest population figure ever recorded, the 2.7% increase shows growth has slowed since the last census.
Between 2001 and 2011 the number of people living in Scotland grew by 233,400 (4.6%).
The other UK censuses showed higher rates of population growth than in Scotland.
The population increased by 6.3% in England and Wales, and by 5.1% in Northern Ireland between 2011 and 2021.
Shifting populations
Across Scotland, the population increased in 17 council areas between 2011 and 2022, with 10 areas seeing decreases and five seeing minimal change.
Most of the council areas in the central belt of the country saw increases in their populations, particularly those around Edinburgh.
The council area that saw the largest increase was Midlothian, jumping 16.1% from 83,187 to 96,600.
Na h-Eileanan Siar saw the biggest percentage decrease (down 5.5%) while the population of Inverclyde dropped from 81,485 to 78,400 over a decade.
The population of the Glasgow City council area is 620,700, up from 593,245 in 2011.
The City of Edinburgh council area also saw its population rise, up from 476,626 in 2011 to 512,700 last year.
NRS said these increases were driven by migration from both within Scotland and elsewhere.
Demographic changes
The census data illustrates the changing age profile of Scotland’s population.
People aged 65 and over now account for a fifth of the overall population, with more older people (1,091,000) than those under the age of 15 (832,300).
By contrast, results from the 1971 census show there were twice as many people under 15 than 65 and over.
In 2011, the two age groups were of a broadly similar size.
Living alone is on the rise, with a 5.8% increase in the number of households with at least one usual resident (2,509,300).
This jump is higher than the increase in the overall population and the NRS points out older people are more likely to live alone or in smaller households.
Return rates
A “lessons learned” review of Scotland’s census is being carried out after it stuggled to achieve its target return rates.
The deadline had to be extended before it finally achieved 89% participation.
England and Wales held their census in 2021, with a 97% completion rate. The previous Scottish census, in 2011, achieved 95% participation.
However, the Scottish government delayed the latest one by a year because of the Covid pandemic, and by the initial deadline of April 2022 it had only achieved an average return rate of 79%.
Some experts suggested that decoupling it from the census in other parts of the UK may have resulted in less publicity and awareness.
