Economists and demographers commented following the 2011 census data that the increasing life expectancy of the UK population and the declining number of births means that there will be fewer workers to shoulder the burden of supporting the elderly.
In order to maintain current population levels, an average fertility rate of 2.1 is required. However, the current fertility rate excluding female immigrants is 1.9 but the figure including female immigrants is 2.0. In the long term, this will help to ease the burden of an aging population.
