National Poll on Social Capital (ENCAS) 2006




The National Poll on Social Capital (ENCAS) is a survey developed by the Secretary of Social Development (SEDESOL) and the United Nations Development Programme in Mexico (UNPD). The objective is to provide information about the social capital of Mexico. Social capital, referring to the norms and social networks that allow collective action, is presumed to be an element that allows greater action power for communities and leads to greater efficiency for public programs through the participation of the citizen in the search for a higher quality of life. For this reason SEDESOL developed a source of data that allows a better understanding of the magnitude of the relationship between social capital, social networks, and collective results.

This study was realized for the first time in 2006 in the urban regions (ENCAS 2006), and in 2011 rural regions were incorporated (ENCAS 2011).

The ARDA has added three additional variables to the original data set to enhance the users' experience on our site.

Collection Procedures

The Secretary of Social Development (SEDESOL) counted with the collaboration of experts from the United Nations Development Programme in Mexico (UNPD) for the design and developments of the survey. The surveying took place through face to face interviews with a representative sampling of urban homes, coordinated by the National Institute of Public Health (INSP).

In all, 2,175 households were visited, from which 2,167 resulted in completed interviews, three resulted in incomplete interviews, and in five other households no one in the home wanted to participate in the interview.

Sampling Procedures

The sample is representative at the national level and for the North, West-Central, South-Southeast, and urban zones. 2,167 households were surveyed, 700 in each region.

The database of the survey was divided into three main parts (combined as one file here); one contains the information corresponding to households, and the other two contain information from the individual level questionnaire. The three archives are combined through the variable "folioh," which is a household identifier. Given that the information corresponds to two distinct units, there are two weights. "Ponder" corresponds to the sample of households and expands the sample to the total population in urban areas in the nation. In this sample, there are 8,854 observations corresponding to the total members in the 2,167 homes. "Ponind" corresponds to the sample resulting from the individual questionnaire, networks and actives. Expanding the sample through the use of the weight measures, you obtain representative information for the population of 18 years and older in the urban areas of Mexico.
