Age structure data

Estimate for 2020:

  • 0-14 years: 18.46% (male 31,374,555/female 30,034,371)
  • 15-24 years: 12.91% (male 21,931,368/female 21,006,463)
  • 25-54 years: 38.92% (male 64,893,670/female 64,564,565)
  • 55-64 years: 12.86% (male 20,690,736/female 22,091,808)
  • 65 years and over: 16.85% (male 25,014,147/female 31,037,419)

Remark: the age structure of a population affects a nation’s key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.
