Annex B. Unweighted and weighted numbers of return migrants and the rest of population

Latin America and the Caribbean

Census data from the IPUMS-International database was also used for LAC countries, except for Mexico, where data are obtained from the 2018 National Survey of Demographic Dynamics (ENADID). The survey years and the unweighted and weighted numbers of return migrants and the rest of the population for each selected Latin American country are presented in Table A B.1.

Sub-Saharan Africa

Return migration to Sub-Saharan Africa was obtained through a 10% sample from the general population census in the IPUMS-International database. Table A B.2 lists the survey years and the unweighted and weighted numbers of return migrants and the rest of the population in selected Sub-Saharan African countries.
