Migration trends are reconstructed with event history models. The reconstruction uses
data collected through migration surveys conducted in cities in three countries (Senegal,
Democratic Republic of Congo, and Ghana) as part of the MAFE (Migration between
Africa and Europe) project. Specifically, two types of data are used: simple data on the
first migration of children of household heads, collected through household surveys,
and full migration histories of children collected in biographic surveys. First, we
evaluate the precision of our estimates using data collected in the household
questionnaire. Next, the sensitivity of our results to different methodological choices
and assumptions is evaluated.
