evidence: The British Office for National Statistics' 2016-based National Population Projections indicated that, if recent trends continue, the UK's population would increase by 3.6 million between mid-2016 and mid-2026. This represents an average annual growth rate of 0.5%. Over the same period, the population of England is projected to grow by 5.9%; for Wales, this figure is 3.1%, while for Scotland and Northern Ireland the figures are 3.2% and 4.2% respectively. These projections did not allow for any possible effects of the UK leaving the European Union.[40] [...] Northern Ireland (2020 estimate) [...] Above the age of 65 years old5 to 15%15 to 20%20 to 25%25% and above
