Bulgaria Population Pyramid 2055
Bulgaria in 2055
United Nations projections (medium variant) put the population of Bulgaria at 5,163,244 in 2055. That would be 8.6% less than in 2045 (5,648,256).
Half of the population would be younger than 48.7 years, with 13.9% children under 15 and 31.1% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
