Emigration Rates From Sample Surveys: An Application to Senegal

Abstract

What is the emigration rate of a country, and how reliable is that figure? Answering these questions is not at all straightforward. Most data on international migration are census data on foreign-born population. These migrant stock data describe the immigrant population in destination countries but offer limited information on the rate at which people leave their country of origin. The emigration rate depends on the number leaving in a given period and the population at risk of leaving, weighted by the duration at risk. Emigration surveys provide a useful data source for estimating emigration rates, provided that the estimation method accounts for sample design. In this study, emigration rates and confidence intervals are estimated from a sample survey of households in the Dakar region in Senegal, which was part of the Migration between Africa and Europe survey. The sample was a stratified two-stage sample with oversampling of households with members abroad or return migrants. A combination of methods of survival analysis (time-to-event data) and replication variance estimation (bootstrapping) yields emigration rates and design-consistent confidence intervals that are representative for the study population.

International Migration and City Growth in the Global South: An Analysis of IPUMS Data for Seven Countries, 1992–2013

“…Cities are expected to constitute major migrant sending areas in early stages of the international migration phenomenon, when push and enabling factors outweigh the pull factors. As observed recently in Dakar (Senegal) and Albanian cities (Willekens, Zinn, and Leuchter 2017; Lerch 2016), this either offsets the cities’ gains or exacerbates the losses from internal migration. In more advanced stages of the international migration phenomenon, when the opportunities to move abroad have diffused into peripheral areas and the domestic economy has developed, cities become major destinations of immigrants.…”

“…During this year, MAFE-Senegal drew a two-stage stratified random sample of households in greater Dakar (Beauchemin 2012;Willekens, Zinn, and Leuchter 2017). The MAFE-Senegal household data are representative of the greater Dakar region, which is home to about a quarter of the country's population, including most of its urban dwellers, and serves as the source of 31 percent of international migrants reported by Senegalese households in the 2001-2002 nationally representative ESAM II survey (Sall 2008).…”

The Features of Labor Emigration From the Slovak Republic

“…The method of questionnaire was used to obtain the opinions of Slovak emigrants. Emigration is the phenomenon that is the most difficult to estimate, the sample surveys are the main source of emigration data today (Willekens et al 2017). Worth to mention that surveys may record emigration intentions, but intentions are often not good predictors of behavior.…”
