DEMOG C175 Lecture Notes - Lecture 9: High School Dropouts, Total Fertility Rate
Document Summary
Number of legal immigrants to the us has spiked a lot, but is fairly low per 1000 residents. Net migration for undocumented and gross migration for legal immigrants. In 1990s, illegal was about equal to legal immigration. During recession, undocumented immigration flattened out and maybe even fell a little. Net legal immigration as share of population growth has been rising steadily since the 1930s. But we"re not taking into account that some population growth is from birth"s of earlier immigrants. If you set immigration to zero, you"re losing the immigrants as well as their future children (losing a lot of population growth). Before 1930 or so, most immigrants were male. Since then, females outnumber males (male-to-female ratio below 1). 1940: war brides (gis returning with brides from abroad) We can assume that a reasonably high proportion of illegal immigrants respond to the survey. Number of foreign-born was about 10-14 million from 1900 to 1970, but rising steadily since then.
