Demographics of Bulgaria

Bulgaria’s demographics are one of the most important factors shaping the country’s economic and social future. According to the United Nations World Population Prospects 2024 (updated 2026), Bulgaria’s population is about 6.67 million as of 2026 — down 23% from its peak of 9 million in 1989. This is the fastest population decline in the European Union, caused by a combination of a low birth rate, average life expectancy and mass emigration after 1989.

For foreigners considering settling inBulgaria, understanding the country’s demographics is important for assessing the labour market, the business environment and society. This article analyses in detail population size, ethnic composition, languages, religion, age structure, urbanisation, birth rates and ageing trends — as well as their implications for immigration and investment policy, based on official data fromWikipedia Demographics of Bulgariaand Eurostat.

Population size and trends

Bulgaria’s population in 2026 is about 6,667,659 according to UN data, down from a peak of 8.98 million in 1989. That is a net loss of 2.3 million people in 37 years — equivalent to 25.6% of the population. Population density is 61 people/km² — significantly below the EU average (109 people/km²). This directly reflects Bulgaria’s demographic crisis.

Three main factors drive population decline in Bulgaria’s demographics. The first is a low birth rate — the crude birth rate (CBR) in 2024 was 9.1 per 1,000 people, and the total fertility rate (TFR) was 1.58 children per woman according to the 2021 census. This is below the replacement level (2.1 children per woman) needed to keep the population stable. The second is a high mortality rate — especially among men, due to smoking, alcohol and work stress.

The third — and largest — is emigration after 1989. About 1.5–2 million Bulgarians have emigrated over the past 35 years, mainly to Germany, the UK, Spain, Greece, Austria and the United States. Most were young people of working age — causing a serious “brain drain”. After Bulgaria joined the EU in 2007, emigration accelerated thanks to free movement within the EU.

UN projections show that Bulgaria’s population will keep falling by 1–1.5% a year over the next 20 years, reaching about 5.2–5.5 million in 2050. This scenario has major implications for the labour market, the social security system and real estate — especially in rural provinces outside Sofia.

Ethnic composition

Bulgaria is relatively ethnically homogeneous — a standout feature of Bulgaria’s demographics. According tothe 2021 census and Britannica, ethnic Bulgarians make up 78.5% of the population. This is one of the highest shares among Eastern European countries — reflecting centuries of cultural convergence between the original Turkic Bulgars and local Slavic tribes.

Turks are the largest ethnic minority, making up 7.8% of the population (about 525,000 people). They are descendants of Muslims who settled during the Ottoman period of 1396–1878 and of converts to Islam. The Turkish community is concentrated in northeastern Bulgaria (Razgrad, Targovishte, Silistra, Shumen) and the eastern Rhodopes (Kardzhali). Turkish is still spoken at home in these areas.

The Roma are officially the second largest ethnic minority — 4.1% of the population according to the 2021 census. However, unofficial estimates by civil society organisations put the real Roma population higher (9–11%), as many Roma declare themselves Bulgarian or Turkish in the census. The Roma community has a younger age structure (a high share of children) and faces significant socio-economic challenges within Bulgaria’s demographic picture.

Ethnic groups making up less than 1% of the population include: Macedonians (usually counted as Bulgarians in official censuses), Armenians, Russians, Greeks, Romanians, Ukrainians, Pomaks (Bulgarian Muslims), Karakachans and Tatars. About 9.4% of the population did not declare an ethnicity in the 2021 census. The foreign community (non-Bulgarian citizens) numbers about 75,000–90,000 as of early 2026, mainly from Russia, Ukraine, the UK, Germany and the Netherlands.

Language and the Cyrillic alphabet

Bulgarian is the official language under the 1991 Constitution. It is a South Slavic language, in the same group as Serbo-Croatian and Slovene, and closely related to Macedonian. Bulgarian is spoken by about 9 million people worldwide, including 6 million Bulgarian citizens and 3 million in the diaspora.

According to the 2021 census — one of the most important data sources for Bulgaria’s demographics — 77% of the population declared Bulgarian as their mother tongue. Turkish is the mother tongue of 8% of the population, and Romani of 3.5%. The rest speak smaller minority languages. Bulgaria’s literacy rate is 98.6% — one of the highest in the EU, the result of a free public education system.

Bulgaria uses the Cyrillic alphabet — an important cultural element. The alphabet was developed in Preslav in the late 9th century by the disciples of Cyril and Methodius, based on the Glagolitic alphabet. Today the Cyrillic alphabet is used by nearly 250 million people worldwide and became the third official alphabet of the European Union after Latin and Greek — after Bulgaria joined the EU in 2007.

For foreigners considering settling, language is the biggest barrier. English is widely spoken in Sofia and among people under 40, especially in the service and technology sectors. However, administrative, banking and legal transactions still require Bulgarian. This matters for the future of Bulgaria’s demographics — the country needs to attract skilled immigrant workers to offset population decline.

Religion

Bulgaria’s traditional religion under the Constitution is Eastern Orthodox Christianity. However, Bulgaria is a secular state — religions are independent and religious institutions are separate from the state. According to the 2021 census, the religious composition shows the most diverse side of Bulgaria’s demographics: Orthodox Christianity 59.4% (down from 76% in 2001), Islam 7.8%, other religions 1.7%, and no religion or undeclared 31.1%.

The Bulgarian Orthodox Church is the largest religious organisation, with 11 dioceses and about 3,000 parishes. Its headquarters are in Sofia (the Alexander Nevsky Cathedral — one of the largest Orthodox cathedrals in the world). Monasteries such as Rila, Bachkovo, Troyan and Rozhen are important spiritual and cultural centres. The Orthodox Church’s historical role in preserving the Bulgarian language and national identity through five centuries of Ottoman rule is an important element of Bulgaria’s demographics.

The Muslim community consists mainly of Turks and Pomaks (Bulgarian Muslims). The Hanafi school of Sunni Islam predominates. The largest mosques are in Sofia (Banya Bashi), Plovdiv (Cuma) and the cities of the eastern Rhodopes. Bulgaria’s Muslim community is considered moderate and well integrated into society — there are no major religious tensions.

Minority religions in Bulgaria’s demographics include Protestantism (mainly traditional American denominations), Roman Catholicism (about 0.7% — concentrated in Plovdiv and some towns in northern Bulgaria), Judaism (about 0.1% — most of the community emigrated to Israel after 1948), the Armenian Apostolic Church and several other small groups. Bulgaria’s overall level of religiosity is low compared with the EU average — about 30% of the population consider themselves non-religious or do not declare a religion.

Age structure and ageing

Age structure is the most serious issue in Bulgaria’s demographics. The median age in 2026 is 45 — one of the highest in the world. Age structure in 2023: 0–14 years 14.03%, 15–64 years 65.17%, 65 and over 20.81%. Compared with the EU average (20.3% aged 65 and over), Bulgaria has a significantly higher share of older people.

The age dependency ratio is 57.3 — meaning every 100 people of working age support 57.3 people outside working age (children + older people). The old-age dependency ratio is 35.3 — 50% higher than the EU average. The potential support ratio is only 2.8 — meaning only 2.8 workers support each older person in Bulgaria’s demographics.

Life expectancy in Bulgaria is 74.5 years (78th in the world) — 6–7 years lower than in Western European countries. Women live 78 years on average, men only 71.1 years — the largest gender gap in the EU. The sex ratio is 1,053 women per 1,000 men. The provinces with the highest life expectancy are Kardzhali and Sofia (76.6 years); the lowest are Montana (72.7), Vratsa (72.8) and Vidin (72.9) — reflecting the gap in quality of life between cities and the countryside.

Rapid ageing creates three major economic challenges for Bulgaria’s demographics. The first is the burden on the pension fund — the number of contributors falls while the number of recipients rises. The second is labour shortages — especially in healthcare, IT and manufacturing. The third is sharply rising healthcare costs — the government must increase investment in health services for older people.

Urbanisation

Urbanisation is an important trend in Bulgaria’s demographics. In 2026, 77.42% of the population lives in urban areas (5.16 million people) and 22.58% in rural areas. The urban population first overtook the rural population in 1969 and has grown steadily since. The process accelerated especially after 1989, when collective planning was dismantled and internal movement became free.

Sofia is the largest city, with about 1.3 million inhabitants (1.7 million including the metro area) — 19.5% of the national population. It is the political, economic, cultural and educational centre — and the centre of Bulgaria’s demographics. Plovdiv is the second largest city (about 350,000 inhabitants) — a UNESCO heritage city with 6,000 years of history. Varna (335,000) is the sea capital and largest port. Burgas (200,000), Ruse (160,000), Stara Zagora (140,000), Pleven (110,000) and Sliven (95,000) are the next largest cities.

Population distribution reflects geography — the most densely populated areas are the Danubian Plain, the Thracian Plain, the Burgas Lowland and the intermontane valleys of the southwest. The most sparsely populated are Strandzha and Dobrudzha in the east and southeast, and the high mountain areas. Sofia, Plovdiv and Varna are the three magnets for internal migration — especially from the northeastern provinces, which are losing population severely according to Bulgaria’s demographics.

For Vietnamese investors consideringBulgaria residency by investment, the concentration of population in Sofia and the big cities creates good real estate opportunities — rents and sale prices have risen steadily by 10–15% a year in central Sofia. By contrast, rural provinces are cheap but carry high liquidity risk because their populations are shrinking.

Birth rate and fertility

Bulgaria’s birth rate is among the lowest in the EU. According to the 2021 census, the total fertility rate (TFR) is 1.58 children per woman, below the replacement level of 2.1. Total births in 2024 were about 65,000. There are significant differences between ethnic groups in Bulgaria’s demographics: Roma women have 2.25 children on average (enough to sustain the population), Turkish women 1.79 and Bulgarian women 1.41.

By religion: Muslim women have 1.83 children, Protestants 1.82, other Christians 1.63, Eastern Orthodox 1.43, Catholics 1.36, Jews 1.27 and Armenians 1.26. Non-religious women have 1.40 children. Despite the differences, fertility remains below replacement level for every group in Bulgaria’s demographics — no ethno-religious group can sustain the population on its own.

Bulgaria has the highest teenage pregnancy rate in the EU — about 10% of all births. This social problem is linked to the Roma community and some economically underdeveloped areas. The 10 municipalities with the largest absolute numbers of teenage mothers in 2022 include Sliven (371), Sofia (345), Plovdiv (196), Pazardzhik (130) and Yambol (123). The government and civil society organisations are running sex education and reproductive health programmes.

The average age of Bulgarian women at first birth has risen from 22 in 1990 to 27.5 in 2024 — reflecting a trend of women focusing on education and careers before marriage. The share of births outside marriage has also risen significantly, from 12% in 1990 to 60% in 2024 — one of the highest in the EU. This is a major cultural shift that has accompanied modernisation.

International migration

International migration is the third most important factor affecting Bulgaria’s demographics after births and deaths. Over the past 35 years, net migration has been almost continuously negative — meaning more Bulgarians have emigrated than immigrants have arrived. The Bulgarian diaspora is estimated at 1.5–2 million people, concentrated in Germany (270,000), Spain (170,000), the UK (100,000), the United States (95,000), Greece (75,000), Austria (50,000) and several other countries.

After Brexit and the 2022 Ukraine crisis, migration flows in Bulgaria’s demographics changed. Some Bulgarians in the UK have returned home. Bulgaria has received about 50,000 Ukrainian refugees since 2022, some of whom have settled permanently. At the same time, the wave of Russians and Belarusians moving to Bulgaria after the crisis has grown significantly — an estimated 30,000–50,000 people in 2022–2025.

Bulgaria is gradually adjusting its immigration policy to offset population decline. The Digital Nomad D visa launched in 12/2025, the €512,000 Golden Visa remains attractive, and programmes to attract highly skilled workers from outside the EU are being expanded. For Vietnamese investors considering settling, Bulgaria is an open and welcoming market for foreigners with capital or skills — unlike some EU countries that are tightening immigration.

The Vietnamese community in Bulgaria numbers about 500–800 people, mainly in Sofia. It is a long-established community dating back to labour cooperation in the 1980s under the socialist regime. Compared with the large Vietnamese communities in Germany (200,000+), the Czech Republic (60,000+) and France (300,000+), the community in Bulgaria is much smaller.

Economic and investment implications

Bulgaria’s demographics have a direct impact on the economic and investment environment. Ageing and a shrinking workforce push wages up — especially in IT, healthcare and technical manufacturing. Average wages in Bulgaria rose 30–40% in 2022–2026, the fastest in the EU. This is both an opportunity (rising consumption, better incomes) and a challenge (rising labour costs, inflationary pressure).

Labour shortages are especially severe in high-skill sectors. Bulgarian businesses have had to recruit workers from other Eastern European countries (Romania, Ukraine, Moldova, Serbia) and Asia (the Philippines, Vietnam, India, Nepal). The government has simplified work permit procedures for non-EU citizens in shortage sectors — a job opportunity for skilled Vietnamese workers that fits the reality of Bulgaria’s demographics.

The real estate market clearly reflects the demographic divide in Bulgaria. In Sofia and the three other big cities (Plovdiv, Varna, Burgas), prices rise 10–15% a year thanks to internal migration. In rural provinces losing population, house prices may fall or stagnate — an opportunity for long-term investors, but with liquidity risk. For Vietnamese investors going throughGolden Visa Bulgaria, Sofia and the Black Sea coast are the best choices for balancing price growth potential and liquidity.

Summary

Bulgaria’s demographics are both the country’s greatest challenge and an opportunity. The combination of the EU’s fastest population decline, its most advanced ageing and mass emigration creates significant economic and social pressure. However, Bulgaria remains relatively ethnically homogeneous, with a stable religious landscape and a safe social environment — important factors for foreigners settling there.

For Vietnamese investors and highly skilled workers considering Bulgaria, the features of Bulgaria’s demographics create labour and real estate markets full of opportunity. Wages are rising, demand for workers in technical sectors is high, and the immigration environment is favourable for people with capital or skills. A detailed understanding of the population structure is key to making investment and settlement decisions that match personal goals.
