ABSTRACT
National population censuses and surveys have historically served as a basis for migration statistics and analysis. The key questions elicit extensive data for examining the population by nativity and demographic change from international migration. These data are valuable from the perspective of not only the destination country but also the origin or sending country. In addition to tracking migrant stocks, analyses provide insights as to unknown migration flows, such as unauthorized migration and emigration, and as to socioeconomic and intergenerational assimilation. Recent changes in census-taking, specifically, introduction of “census-quality” surveys, enhance the availability of migration data.
