Population of Bulgaria from 1881 to 2020, by gender (in millions)

Population of Bulgaria by gender 1881-2020 This graphic shows the population of men and women in Bulgaria from 1881 to 2020, given in millions of people. As we can see, the population gradually increases from when these records began until 1985 when it then begins to decrease with each entry. The increase from 1881 to 1985 is quite gradual, although the intervals between each entry vary which make it difficult to determine how Bulgaria was influenced during major international events, such as the Balkan and World Wars. From the beginning of this period, the number of women is slightly lower than the number of men, however this fluctuates in the middle of the 20th century, before the gap begins to widen a lot more as the population decreases in 1985. Much of this is because men typically migrate to other countries in search of work at a higher rate than women. Bulgaria reaches it's peak population size in 1985 with 8.98 million inhabitants (4.45 million men and 4.53 million women), but then the number decreases each year, finishing at 3.37 million males and 3.57 million females in 2020 (200 thousand more women than men). This drop in population size has been attributed to the economic collapse at the end of communism in Eastern Europe, causing many to leave the country in search of work elsewhere. Bulgaria also has one of the lowest fertility rates in the world, with 8.7 births per 1,000 people per year in 2018.
