Summary

United Kingdom in 2037

With a projected median age of 42.8 years, the United Kingdom would have a youth dependency ratio of 23.9 and an old-age dependency ratio of 36.9 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
