Bulgaria’s population stands at a critical juncture in early 2026, with real-time estimates placing the figure around 6.69 million people. This number reflects a nation experiencing steady decline, a trend that has persisted for over three decades. Reliable sources such as Worldometer, drawing from United Nations data, report the current population hovering near 6,690,000 as of mid-January 2026, with live population clocks updating continuously to account for births, deaths, and migration flows.

This decline traces back to the peak of nearly 9 million in 1989, just before major political shifts opened borders and accelerated emigration. Today, Bulgaria grapples with one of Europe’s most pronounced demographic contractions, driven by low birth rates, higher mortality, and ongoing outward migration. The situation raises important questions about economic sustainability, workforce availability, and social services in the years ahead.

Understanding these dynamics requires examining the interplay of historical events, current statistics, and future projections. Bulgaria’s demographic story highlights broader European patterns of aging societies, yet its pace and scale make it particularly noteworthy. The numbers reveal a country in transition, where population changes influence everything from labor markets to regional development.

Current Population Snapshot

As of January 2026, Bulgaria’s population registers approximately 6,690,000 according to live estimates from Worldometer, based on United Nations elaborations. Countrymeters provides a similar real-time figure around 6,681,000. These live population clocks track daily changes, showing roughly 163 births and 280 deaths per day, resulting in a net natural decrease.

Population density remains low at about 62 people per square kilometer, reflecting the country’s land area of over 108,000 square kilometers. Urban areas house roughly 77 percent of residents, with Sofia alone accounting for a significant portion.

Historical Trends in Population Decline

Bulgaria’s population reached its highest point in 1989 at over 9 million. Since then, consistent losses have reduced the total by more than 25 percent. The 2021 census recorded about 6.5 million, down from 7.36 million in 2011.

Key factors include the post-communist transition, which spurred massive emigration, particularly among younger and skilled workers seeking opportunities abroad. Negative natural increase, where deaths outnumber births, has compounded the issue since the early 1990s.

Historical data illustrates the shift:

• 1985: ~8.96 million
• 1990: ~8.82 million
• 2000: ~8.00 million
• 2010: ~7.44 million
• 2020: ~6.93 million

This steady downward trajectory positions Bulgaria among the fastest-declining populations in the European Union.

Key Demographic Indicators

Several metrics define Bulgaria’s current demographic profile.

Fertility Rate The total fertility rate sits at approximately 1.74 children per woman in 2025 projections, well below the replacement level of 2.1. This low rate has persisted for decades, with slight fluctuations but no sustained recovery.

Median Age The median age stands at 44.8 years, indicating an aging society. This figure has risen from 35.6 in 1990, signaling fewer young people entering the workforce.

Life Expectancy Life expectancy at birth averages around 73.6 years, below many Western European counterparts, influenced by health and lifestyle factors.

Urbanization Urban population percentage has climbed to about 77 percent, concentrating residents in cities while rural areas face depopulation.

Ethnic Composition and Diversity

Bulgaria maintains a diverse ethnic makeup. Ethnic Bulgarians constitute the majority at around 77 percent. Turkish and Balkan Gagauz groups represent about 8 percent, while Romani communities account for roughly 4.4 percent, with some estimates suggesting higher figures due to underreporting. Smaller minorities include Russians, Armenians, and others.

This composition influences regional demographics, with certain areas showing higher fertility in minority communities.

Drivers Behind the Decline

Multiple interconnected factors fuel Bulgaria’s population shrinkage.

Low fertility stems from economic pressures, delayed family formation, and changing social norms. The average age of mothers at first birth has increased, contributing to fewer overall births.

High emigration, especially post-EU accession in 2007, has drained young talent. Net migration often remains negative, though occasional positive inflows occur.

Elevated mortality rates, particularly among older groups, exacerbate natural decrease. The COVID-19 period intensified this trend temporarily.

Aging Society and Its Implications

Bulgaria faces rapid aging, with over 22 percent of the population aged 65 or older in recent estimates. This shift increases dependency ratios, straining pension systems and healthcare.

The working-age population shrinks, posing challenges for economic growth and labor supply. Rural depopulation creates “desertified” areas with few young residents.

Population Projections for the Future

Projections indicate continued decline. By 2030, the population may drop to around 6.46 million, with further reductions to 5.4 million by 2050 under medium variants from United Nations data.

Here is a summary table of key population projections:

Year	Projected Population	Yearly % Change	Key Factor
2026	~6,650,000	-0.7%	Ongoing natural decrease
2030	6,458,000	-0.78%	Continued emigration
2035	6,183,000	-0.87%	Aging acceleration
2040	5,908,000	-0.91%	Low fertility persistence
2050	5,402,000	-0.89%	Long-term structural shift

These forecasts underscore the need for adaptive policies.

Challenges and Broader Impacts

Demographic changes affect economic vitality, with labor shortages in key sectors. Social services face pressure from an inverted age pyramid.

Regional disparities widen, as urban centers like Sofia grow relatively stable while rural municipalities empty.

Looking Ahead: A Nation in Transition

Bulgaria’s population trajectory reflects profound transformations over recent decades. From a peak in the late 1980s to the current level near 6.7 million and ongoing decline, the country navigates complex challenges tied to low fertility, aging, and migration. Live population tools and reliable estimates from sources like the United Nations provide essential real-time insights into these shifts.

The path forward depends on addressing root causes through sustained efforts to support families, retain talent, and foster inclusive growth. While projections point to further reductions, strategic adaptations could mitigate impacts and build resilience. Bulgaria’s demographic story serves as a compelling case study in how societies evolve amid global trends, offering lessons for balanced development and long-term stability. Monitoring these changes closely remains essential for informed planning and a sustainable future.
