[Levels and trends in international migration in Mexico using census data, 1970-1990]

"The author presents estimates of interstate migration [in Mexico] by age and gender for the country's overall internal migration and for each of the states, without specifying age or gender, for the five years leading up to the censuses carried out in 1970, 1980 and 1990. Estimates are based directly on census figures. On the whole, internal migration was lowest in the 80s and slightly higher in the 90s than in the 70s." (SUMMARY IN ENG)
