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, Tutsi, and Twa. 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.

Demographic and Health Surveys

Total Fertility Rate and Crude Birth Rate :
Fertility data as of 2010 : 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 of 1.8 children per couple nationwide; 1.1 in urban areas and 2.0 in rural areas. However, the number of desired children appears to be based on the lowest-desired rate - that of paired but unmarried men rather than the highest 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
