DEMOGRAPHICS
A census is taken simultaneously in all parts of the UK every ten years. In the 2011 census the total population of the United Kingdom was 63,181,775. It is the third-largest in the European Union, the fifth-largest in the Commonwealth and the 22nd-largest in the world. In mid-2014 and mid-2015 net long-term international migration contributed more to population growth. In mid-2012 and mid-2013 natural change contributed the most to population growth. Between 2001 and 2011 the population increased by an average annual rate of approximately 0.7 per cent. This compares to 0.3 per cent per year in the period 1991 to 2001 and 0.2 per cent in the decade 1981 to 1991. The 2011 census also confirmed that the proportion of the population aged 0–14 has nearly halved (31 per cent in 1911 compared to 18 in 2011) and the proportion of older people aged 65 and over has more than tripled (from 5 per cent to 16 per cent).
England's population in 2011 was 53 million. It is one of the most densely populated countries in the world, with 420 people resident per square kilometre in mid-2015 with a particular concentration in London and the south-east. The 2011 census put Scotland's population at 5.3 million, Wales at 3.06 million and Northern Ireland at 1.81 million.
In 2017 the average total fertility rate (TFR) across the UK was 1.74 children born per woman. While a rising birth rate is contributing to current population growth, it remains considerably below the baby boom peak of 2.95 children per woman in 1964, or the high of 6.02 children born per woman in 1815, below the replacement rate of 2.1, but higher than the 2001 record low of 1.63. In 2011, 47.3 per cent of births in the UK were to unmarried women. The Office for National Statistics published a bulletin in 2015 showing that, out of the UK population aged 16 and over, 1.7 per cent identify as lesbian, gay, or bisexual (2.0 per cent of males and 1.5 per cent of females); 4.5 per cent of respondents responded with "other", "I don't know", or did not respond. In 2018 the median age of the UK population was 41.7 years.
