I’m working on an immigration-related project using the census data from across the world accessed from IPUMS International (around the year 2010). After some exploration, I found that the variable for “year of immigration” (harmonized or uncategorized) is largely missing for most countries. When I restrict my sample to countries with available nativity, country of birth, and year of immigration variables, I end up with less than 15 countries.
I’m curious whether this is normal for other users, or am I doing something wrong or missing something? A follow-up question is whether the IPUMS International dataset is suitable for cross-country research on immigrants, based on the availability of relevant variables. I would appreciate any feedback or comments!
