Errors in ENVIPE 2012 database

There are inconsistencies in the available database of Encuesta Nacional de Victimización y Percepción sobre Seguridad Pública 2012 (ENVIPE)

Using the PSUs, weights and strata specified (download the “Descripción de archivos¨ file). The estimates differ signficantly from the ones stated in ¨Tabulados básicos” For example, in Tabulados básicos, the total population of 18+ is 76,228,271 and with the database provide (¨Microdatos¨) is 64,333,905.

The above implies that the number of 18+ people decreased from 74,500,383 to 64,333,905 in just one year. Something is going wrong here.
