Household and individual variables were collected using an extensive household survey that includes information on household structure, household consumption, expenditure, income, health indicators and educational attendance. The survey was conducted between June and October of 2002. In this subsection, we will comment on the main variables used in the analysis. Table 1 gives the descriptive statistics and definitions of the variables. Though the survey was administered to 122 municipalities, we can only have 102 in our estimating sample. The difference is due to missing values in community variables, and because we choose to include only municipalities where at.
