Lithuania Population Pyramid 2031
Year
2031Lithuania in 2031
In 2031, Lithuania is projected to have a population of 2,684,469 people. Ten years before, in 2021, the projected population is still 2,794,488 — a ten-year decline of 3.9%.
Half of the population would be younger than 45.1 years, with 13.0% children under 15 and 23.5% 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.
