PROGRESA (currently Oportunidades) was the first conditional cash transfer program to rely on strict socioeconomic targeting to achieve substantial improvements in the health, education and nutrition of the rural poor. From 2004 to 2010, its payroll consisted of 5 million households, and approximately 25% of the Mexican population. The program was first implemented in 1997, and Agustín Escobar Latapí and Mercedes González de la Rocha were in charge of the official qualitative evaluation of the program from 1999 to 2008. In this site, the authors provide access to the text files resulting from these evaluations.
