As of 2023, the average age in Belarus has been increasing, indicating a growing proportion of older adults. This demographic shift is accompanied by low birth rates and emigration, particularly among the working-age population, which collectively affect the country’s population growth rate. Moreover, political unrest and economic uncertainties have also contributed to the emigration trend as citizens seek stability. Additionally, health factors, including a relatively high mortality rate and issues related to alcohol consumption, further influence the population dynamics.
