Demographics of Burundi, Number of inhabitants in thousands.

At 206.1 persons per km², Burundi has the second-largest population density in Sub-Saharan Africa. Most people live on farms near areas of fertile volcanic soil. The population is made up of three major ethnic groups – Hutu (Bahutu), Tutsi (Batutsi or Watusi), and Twa (Batwa). Kirundi is the common language. Intermarriage takes place frequently between the Hutus and Tutsis. The terms "pastoralist" and "agriculturist", often used as ethnic designations for Watusi and Bahutu, respectively, are only occupational titles which vary among individuals and groups. Although Hutus encompass the majority of the population, historically Tutsis have been politically and economically dominant.

Population

Estimated population, fertility rate and net reproduction rate by year according to United Nations estimates

According to the 2022 revision of the World Population Prospects, the total population was 11,891,000 in 2020, compared to only 2 309 000 in 1950.

Fertility and births

Total Fertility Rate (TFR) (Wanted Fertility Rate) and Crude Birth Rate (CBR):

Year	Total		Urban		Rural
	CBR	TFR	CBR	TFR	CBR	TFR
1987		6.6 (5.3)		5.2 (4.2)		6.6 (5.4)
2010	44.5	6.4 (4.2)	37.3	4.8 (3.4)	45.3	6.6 (4.3)
2016–17	37.9	5.5 (3.6)	33.0	4.1 (3.0)	38.5	5.7 (3.7)

Fertility data as of 2010 (DHS Program): The fertility rate in the Bujumbura Mairie Province fell to 3.7 by 2016–2017; the other regions were not aggregated in the report, for easy reference and comparison to the below chart. Per the 2016-2017 report, the average number of desired children in Burundi, nationwide, by both men and women of 15 to 49 years of age who are either paired up or married, is 4 children or less, and slightly less for men than for women. Per the report, this suggests an excess fecundity (more children than desired) of 1.8 children per couple nationwide; 1.1 in urban areas (where 3.0 children are desired, and the fertility rate is 4.1) and 2.0 in rural areas (where 3.7 children are desired and the fertility rate is 5.7). However, the number of desired children appears to be based on the lowest-desired rate - that of paired but unmarried men (3.7 children) rather than the highest (4.0, desired by married women) or even an overall average.

Region	Total fertility rate	Percentage of women age 15-49 currently pregnant	Mean number of children ever born to women age 40–49
Bujumbura Mairie	4.2	7.9%	5.3
Nord	6.7	10.1%	6.4
Centre-Est	6.3	10.5%	6.6
Ouest	7.1	11.7%	7.2
Sud	6.2	10.8%	6.8

Note: estimates for this country explicitly take into account the effects of excess mortality due to AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population and growth rates, and changes in the distribution of population by age and sex than would otherwise be expected (July 2015 est.)
