Community Level

COMMUN
A community-level file that provides information regarding community and municipio characteristics from 1950 to the time of the survey. Included is information regarding population, labor force, industry, natural resources, agriculture, standard of living, community development, infrastructure, institutions, and migration prevalence. We also offer homicides rates from 1990 to 2019.

PRATIO
A community-level file that provides the annual migration prevalence ratio starting in 1940 up to the survey year. Prevalence ratio was first described by Douglas Massey et. al. in their article "Continuities in Transnational Migration: An Analysis of Nineteen Mexican Communities." American Journal of Sociology Vol. 99, No. 6 (May 1994), pp. 1492-1533.

National Level

NATLYEAR
A longitudinal supplemental file containing several national-level indicators of macroeconomic conditions in the United States and Mexico from 1965 to 2017: border crossing measures, INS budget and activities, intra- and inter-country financial indicators, trade levels, and workforce statistics.

A longitudinal supplemental file containing selected indicators of Mexico-U.S. migration, border enforcement, population, and trade for each year from 1900 through 2017.

MSA Level - no longer updated

MSACROSS
A cross-sectional supplemental file providing the cost of living index (1983) for each U.S. urban geographic code contained in the Mexican Migration Project files (as of June 1997), allowing researchers to adjust for differences in price levels across metropolitan areas at a particular point in time.

MSAYEAR
A longitudinal supplemental file containing information on the consumer price index (base 1982-84), unemployment rate, number of Mexicans who became legal residents as a percent of the total Mexican foreign-born population and total population size for all U.S. urban areas used in the Mexican Migration Project (as of June 1997), over selected years.
