United Kingdom Population Pyramid 2001
United Kingdom in 2001
As of 2001, the United Kingdom counted 59,288,090 inhabitants. A decade earlier, in 1991, the population was 57,555,192; it has grown by 3.0% since.
Half of the population was younger than 37.9 years; 18.7% were children under 15 and 15.9% were 65 or older. The pyramid is stationary: cohort sizes are roughly even through the younger ages, reflecting fertility close to replacement level and slow population change.
