The population of the UK in mid-2016 was 65.6 million.

The population is growing and is projected to reach 70 million by 2030 and 73 million by 2040. The population of England is projected to grow by 8.0% between 2016 and 2030, Northern Ireland by 5.3%, Wales by 3.9% and Scotland by 1.5%.

The UK has an aging population: there are around 12.4 million people of pensionable age today.  Population projections predict that the elderly population will continue to rise, with around 16.3 million people of pensionable age by 2041.


Since 1960, the UK population has grown by 13.3million people.  Until 1999, the main driver in population growth was natural change (births and deaths).  However, between 1999 and 2011 net international migration was the greatest contributing factor.  Net migration fell in 2012 and 2013 but was the largest component in both 2014 and 2015.
