Belarus Population Pyramid 2100
Belarus in 2100
In 2100, Belarus is projected to have a population of 4,350,962 people. Ten years before, in 2090, the projected population is still 4,857,563 — a ten-year decline of 10.4%.
The median age is projected at 54.5 years, with 19.6 children under 15 and 66.8 people aged 65 or over for every 100 people of working age (15–64). The narrow base of the pyramid marks a constrictive age structure: fertility below replacement level and a rising share of older people.
