Demographic features of the population of Burundi include population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects.

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.

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.
