This country’s population has decreased by 844,000 people as compared to the previous census in 2011. This is the largest decrease ever recorded. More than half of the decline is due to the natural population decrease and the rest is due to migration.

In 1992, 24% of Bulgaria’s population was aged 14 or under and 14% was aged 65 and above. In 2021, 14% of the population is aged 14 and under and 24% of the people are aged 65 and above.
