This is a demography of the population of Namibia including population density, ethnicity, education level, health of the populace, economic status, religious affiliations and other aspects of the population.

As required by the Namibian Statistics Act #66 of 1976, and in accordance with United Nations recommendations, a census is conducted every ten years. After Namibian independence the first Population and Housing Census was carried out in 1991, further rounds followed in 2001 and 2011. The data collection method is to count every person resident in Namibia wherever they happen to be. This is called the de facto method. For enumeration purposes the country is demarcated into 4,042 enumeration areas. These areas overlap with constituency boundaries in order to get reliable data for election purposes as well.

The 2011 Population and Housing Census counted 2,113,077 inhabitants of Namibia. Between 2001 and 2011 the annual population growth was 1.4%, down from 2.6% in the previous ten–year period.

In 2011 the total fertility rate was 3.6 children per woman, down from 4.1 in 2001.
