numerous among immigrants and because employment-based immigrants, in whom there is great interest, are a relatively small category, a stratified random sample was drawn, undersampling children and oversampling the employment-based.
There are two types of data that are pertinent. The first is data on the usual sociodemographic and economic characteristics and activities, so that immigrants and their children can be compared with native-born persons. The second is data on characteristics and behavior unique to immigrants. The first type of data include marital and employment histories, and the second type include migration and language-acquisition histories.
