Mexican Health and Aging Study

The Mexican Health and Aging Study (MHAS) is a prospective panel study of health and aging in Mexico. MHAS is nationally representative of the 13 million Mexicans born prior to 1951. The survey has national and urban/rural representation. MHAS respondents were identified in conjunction with the 2000 National Employment Survey/Encuesta Nacional de Empleo (ENE):Spouse/partners of eligible respondents were interviewed, even if the spouse was born after 1950. The six Mexican states which are origin of 40% of all migrants to the U.S. were over-sampled at a rate of slightly less than 2:1. Follow-up interviews with surviving respondents will be conducted in the second quarter of 2003. Interviews with next-of-kin will be conducted on deceased respondents.
