Demographics

Ethnic groups in Bulgaria (2021 census)

According to the government's official 2022 estimate, the population of Bulgaria consists of 6,447,710 people, down from 6,519,789 according to the last official census in 2021. The majority of the population, 72.5%, reside in urban areas. As of 2019, Sofia is the most populated urban centre with 1,241,675 people, followed by Plovdiv (346,893), Varna (336,505), Burgas (202,434) and Ruse (142,902). Bulgarians are the main ethnic group and constitute 84.6% of the population. Turkish and Roma minorities account for 8.4 and 4.4%, respectively; some 40 smaller minorities account for 1.3%, and 1.3% do not self-identify with an ethnic group. The Roma minority is usually underestimated in census data and may represent up to 11% of the population. Population density is 55-60 per square kilometre (ultimo 2023), almost half the European Union average.

Bulgaria is in a state of demographic crisis. It has had negative population growth since 1989, when the post-Cold War economic collapse caused a long-lasting emigration wave. Some 937,000 to 1,200,000 people—mostly young adults—had left the country by 2005. The majority of children are born to unmarried women. In 2024, the average total fertility rate (TFR) in Bulgaria was 1.59 children per woman, a slight increase from 1.56 in 2018, and well above the all-time low of 1.1 in 1997, but still below the replacement rate of 2.1 and considerably below the historical high of 5.83 children per woman in 1905. Bulgaria thus has one of the oldest populations in the world, with an average age of 43 years. Furthermore, a third of all households consist of only one person and 75.5% of families do not have children under the age of 16. The resulting birth rates are among the lowest in the world while death rates are among the highest.

Bulgaria scores high in gender equality, ranking 18th in the 2018 Global Gender Gap Report. Although women's suffrage was enabled relatively late, in 1937, women today have equal political rights, high workforce participation and legally mandated equal pay. In 2021, market research agency Reboot Online ranked Bulgaria as the best European country for women to work. Bulgaria has the highest ratio of female ICT researchers in the EU, as well as the second-highest ratio of females in the technology sector at 44.6% of the workforce. High levels of female participation are a legacy of the Socialist era.
