This entry includes the figure for the difference between the number of persons entering and leaving a country during the year per 1,000 persons (based on midyear population). An excess of persons entering the country is referred to as net immigration (e.g., 3.56 migrants/1,000 population); an excess of persons leaving the country as net emigration (e.g., -9.26 migrants/1,000 population). The net migration rate indicates the contribution of migration to the overall level of population change. The net migration rate does not distinguish between economic migrants, refugees, and other types of migrants nor does it distinguish between lawful migrants and undocumented migrants.
-0.01 migrant(s)/1,000 population
note: repatriation of Ethiopian refugees residing in Sudan is expected to continue for several years; some Sudanese, Somali, and Eritrean refugees, who fled to Ethiopia from the fighting or famine in their own countries, continue to return to their homes (2011 est.)
