   /statistics/household-size

From the UN Population Division's Database on Household Size and Composition, which applies one estimation method to censuses, household surveys and national tabulations. Where a country has two sources in its newest year, the row is the one the Division's own country dashboard shows. One impossible value at source, and two surveys covering only part of Somalia, are set aside.
