Structural changes in migration flows in recent years have brought important demographic changes to the Latin America and Caribbean region. These changes have generated the need to increase the efforts of National Statistical Offices (NSOs) of each country to periodically collect and publish a set of socioeconomic indicators of the wellbeing of their inhabitants, especially migrants. This note identifies the existing coverage of data on migrants in the censuses and regular household surveys that are carried out in the region. To this end, it provides a review of the data that has been collected at the IDB and published on the web sites of the NSOs of each country. Based on this data, the report identifies whether it is possible to identify migrants in the data, how representative the sample is, and for which years (beginning in 2010). The note includes a summary by country of the data available, indicating observed discrepancies in the measures of the migrant population among different sources of data for the country.
