Various estimates have put Bulgaria's medieval population at 1.1 million in 700 AD and 2.6 million in 1365. ^[5] At the 2011 census, the population inhabiting Bulgaria was 7,364,570 in total, but the 2021 Census calculated that the population had declined to 6.5 million. ^{[6] [7]} The peak was in 1989, the year when the borders opened after a half of a century of communist regime, when the population numbered 9,009,018.

Birth rates and fertility

Historical birth and fertility rates

The first reliable data about fertility and natural interest rates in the Bulgarian lands date back to the mid-1800s.

According to Turkish statistician Kemal Karpat, Non-Muslims, Bulgarians included, in the Ottoman Empire received a remarkable boost in fertility in the early 1830s. Their average growth rate climbed up to 2% per year, compared to zero among Muslims, who suffered from demographic stagnation. ^[26]

The same trend continued well after Bulgaria's Liberation from Ottoman rule in 1878. ^[27] Until the early 1890s, Muslim birth rates in Bulgaria hesitated in the low 20s, dwarfed by rates of + 40‰ among Orthodox Christians, while natural increase rates hovered around zero. ^[27] The ongoing Muslim demographic crisis and the heavy migration to Turkey were the two primary reasons for the rapid decrease in Bulgaria's Muslim and Turkish population between 1880 and 1910, from 28.7% in 1880 to 13.8% in 1910 for Muslims and from 26.2% to 10.7% for Turks.

Muslim birth and natural increase rates started climbing slowly from the late 1890s but only surpassed Orthodox ones in 1924. Nevertheless, it was not the Eastern Orthodox but rather Bulgaria's Roman Catholics that had the highest birth rate during the period, though usually offset by very high mortality rates.

In the 1930s and 1940s, ethnic Bulgarians completed stage 2 of their demographic transition, and crude birth rate among them fell to a mere 23.3‰ by 1946, or twice as low as the birth rate of Bulgaria's two largest minorities, Turks (40.9‰) and Roma (47.2‰). ^[30] At the same time, due to higher mortality, the rate of natural increase among Bulgarian Turks was almost identical to that among ethnic Bulgarians (12.1‰ vs. 11.1‰), while the rate among the Romani was twice as high (23.1‰). ^[30]

Present-day

A total of 64,984 live births were recorded in Bulgaria in 2016, giving the country a crude birth rate of 9.1‰. ^[31]

Bulgaria has a low total fertility rate of 1.58 children per woman (according to the 2021 Census). This is up significantly from the late 1990s, but still below replacement and not enough to prevent further population decline, especially with emigration. Provinces with large Roma populations (for example Sliven, Montana and Yambol) tend to have higher fertility rates (and higher death rates) compared to other areas, whereas Turkish fertility is similar to the Bulgarian majority. ^[32] The average number of (live births) children in 2021 was 1.47 for all women (aged 12 or more), ranging from 0.04 children for women between the ages of 12-19 to 1.92 children per women between the ages of 70-79. The distribution by ethnicity shows that only among women who identify themselves as belonging to the Roma ethnic group, the average number of children is sufficient for simple reproduction - 2.25 children, mainly because of the significantly younger age structure and low educational level of this group, followed by the Turkish ethnic group with 1.79 children and 1.41 children for women who self-identified as belonging to the Bulgarian ethnic. ^[33] The distribution of the average number of live births by religion changes from 1.83 children for Muslim women and 1.82 children for Protestant women, followed by 'other Christian' (1.63), Eastern Orthodox (1.43), Catholic (1.36), Jewish (1.27) and Armenian Apostolic (1.26). Women without religion had an average number of 1.40 children.

Demographic policies

The progressive decrease of the Bulgarian population is hindering economic growth and welfare improvement, and the management measures taken to mitigate the negative consequences do not address the essence of the problem. The Government Program for the period 2017 - 2021 is the first one that aims at overturning the trend. The program also identifies the priority means for achieving this goal: measures to increase the birth rate, reduce youth emigration, and build up regulatory and institutional capacity to implement a modern immigration policy tailored to the needs of the Bulgarian business. ^{[45] [46]}

1 According to x files of the state, the number of the Romani was reduced by 25,000 in 1956. [49] 2 In the 1946 and the 1956 census, the population of Pirin Macedonia was forced to list as ethnic Macedonians by the Communist government in preparation of a planned federation between the People's Republic of Bulgaria and Socialist Yugoslavia, with "United Macedonia" as the connecting piece. The deal fell through, and the policy was eventually reversed in 1958. [50] [51] 3 Note that the distinction between Sarakatsani and Greeks, and between Vlachs and both Aromanians and Romanians, is fluid. Sarakatsani were counted as Greeks in the 1900, 1920, 1926, 1934, and 1965 censuses.

1No data collected about ethnic group in 1985 census. 2 There are strong indications that the number of ethnic Romani in the 1965 and 1975 census was manipulated. 3 Note that the distinction between Sarakatsani and Greeks, and between Vlachs and both Aromanians and Romanians, is fluid. Sarakatsani were counted as Greeks in the 1900, 1920, 1926, 1934, and 1965 censuses.

1 The category pertains to citizens whose data has been collected from administrative databases. 2 The online stage of the 2021 Census was subjected to repeated DDoS attacks. [57] As a result, much fewer citizens than expected, especially in major urban areas, were able to take the online census, and the number of hired census assessors proved inadequate to ensure full census coverage in most major cities. Thus, the City of Sofia had a record-high number of no returns, 166,044, or 35.5% of the country total, despite being home to only 19.5% of the population. 3 The province with most missing returns for 2011 (21.7%), Smolyan, had record-high participation in 2021, with only 736 or 0.7% missing returns.

The 2001 census defines an ethnic group as a "community of people, related to each other by origin and language, and close to each other by mode of life and culture"; and one's mother tongue as "the language a person speaks best and usually uses for communication in the family (household)". ^[63] According to the 2011 census, among the Bulgarians 99.4% indicate Bulgarian as a mother tongue, 0.3% - Turkish/Balkan gagauz, 0.1% - Roma and 0.1% others; among Turks 96.6% have pointed the Turkish/Balkan Gagauz as a mother tongue and 3.2% - Bulgarian; among the Roma 85% indicate Roma language as a mother tongue, 7.5% - Bulgarian, 6.7% - Turkish/Balkan gagauz and 0.6% - Romanian.

Religion

Main article: Religion in Bulgaria

Bulgaria's traditional religion according to the constitution is the Orthodox Christianity, while Bulgaria is a secular state too. Since the last two censuses (2001 and 2011) provide widely divergent results, they are both shown in the table below.

Migration

Main article: Immigration to Bulgaria

Historical migration

The first censuses of the Principality of Bulgaria and the autonomous province of Eastern Rumelia in 1880 recorded 31,786 and 17,970 Bulgarian refugees from Macedonia and Ottoman Thrace, respectively, who accounted for 1.38% of the population of the Principality an 2.20% of the population of the autonomous province, respectively. ^{[69] [70] [71]} The census of the Principality also counted a total of 37,635 people, or 1.88% of the population, born in a country other than the Ottoman Empire, mostly Bulgarians from Romania, Northern Dobruja and Bessarabia. ^[69] By 1887, when the first joint census of the Principality and the autonomous province was conducted following their peaceful unification in 1885, the number of the refugees from the Ottoman Empire had grown to 54,462 people, or 1.73% of the population, while the rest of the foreign-born population had fallen to 31,637 people, 9,831 of whom born in the Russian Empire, 11,843 in Romania, 2,690 in Serbia and 7,273 elsewhere. ^[72]

According to the 1910 census, 300,000 or almost 10% of the ethnic Bulgarians were born in another Bulgarian municipality than the one they were enumerated in. The same data shows that the foreign-born ethnic Bulgarians numbered 78,000, or 2% of them, most numerous of whom were the 61,000 Ottoman-born, 9,000 Romanian-born and by less than 2,000 Austro-Hungarian, Serbian and Russian-born. ^[73] By the 1926 census, there had been 253,000 refugees with granted households and land or citizenship but with many more in towns of uncertain number. 35% came from Eastern Thrace, 30% came from Greek Macedonia, another 18% from Western Thrace, 8% from Dobruja, 4% from the Western Outlands, 3% from Asia Minor, and 2% from North Macedonia. They constituted 6% of the country's population. In 1940, 70,000 Bulgarians were exchanged from Northern Dobruja. The total number of refugees in 1878-1940 is estimated at between 700,000 and 1,200,000. ^[74] In 1950-1951, around 150,000 Turks left Bulgaria for Turkey, and again in 1989.

26. Karpat, K.H. (1985). Ottoman population, 1830-1914: demographic and social characteristics. Madison, Wis: University of Wisconsin Press. p. 70. The assessment of fertility rates is an absolute necessity for the understanding of the growth rate of the Ottoman population. It is generally assumed that during the first thirtv years of the nineteenth century the Ottoman population decreased, beginning to increase again after 1850. This assumption is one-sided and only partly true, for it ignores the differences in growth rates between Muslim and non-Muslim groups. The non-Muslim population actually grew at a fairly fast rate after the 1830s—probably 2 percent annually; the Muslim population declined or remained the same in number. There are indications, however, that fertility rates among the Muslims began to increase after 1850. The causes of the disproportionate fertility rates among the two groups are to be found in the special economic and social conditions which favored non-Muslims and penalized the Muslims, especially Turks. Male Turks spent their peak reproductive years in military service and were unable to marry and settle down to take advantage of economic opportunities. Then, when in the nineteenth century the Ottoman state was exposed to the influence of the European capitalist economy and to intensified internal and international trade, several non-Muslim groups became the early recipients of the economic benefits—and the promoters as well—of the new economic system.
