Bulgaria Population Pyramid 2035
Bulgaria in 2035
By 2035, the population of Bulgaria is expected to reach 6,183,114. Compared with 2025, when the projection stands at 6,714,560, that represents a decline of 7.9% over ten years.
Half of the population would be younger than 48.2 years, with 13.7% children under 15 and 24.3% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
