The Mexico data we have is accessible through http://sedac.ciesin.columbia.edu/home-page/mexico.html. We do not have fertility rate and interstate migration data. There are data on age structure of populations.
The source of these data is INEGI, El Instituto Nacional de Estadmstica, Geografma e Informatica. INEGI is the authoritative source for available data. See http://www.inegi.gob.mx.
