By comparing population pyramids, the changing structure of the UK population can be seen:

  • In 2001 the highest number of people were in the 30-39 age group. This is partly due to high birth rates in the 1960s (baby boom) .
  • By 2015 the highest number of people were were in the 40-49 age group as the baby boom generation got older.
  • Between 2001 and 2015, the proportion of 20-29 increased due to increasing numbers of young migrants.
  • The proportion of people aged 0-39 increased by 3% between 2001 and 2015. The number of people over 39 increased by 18%, showing that the UK’s population is getting older.

  • Birth rate and death rate have fallen over the past 300 years and it has moved through stages 1-3 of the DTM (stage 1: before 1760, stage 2: 1760 -1870, stage 3: 1870-1950).
  • Birth rates are now low (12 per 1000 people) and death rates are as well (9 per 1000 people) meaning that population growth is still occuring but slowly.
  • The UK hasn’t yet reached stage 5, when birth rates are lower than death rates, and population starts to decrease.
