Social environment index

Variable Definition

This index aims to summarize the domains of education, water acces, sanitation and overcrowding. For its construction, one measure from each of the four domains of education (proportion of the population aged 25 or older who completed primary education or above), water access (proportion of households with piped water access inside the dwelling), sanitation (proportion of households connected to a public sewage network), and overcrowding (proportion of households with more than 3 people per room) was selected. Each measure was transformed into a Z-score using the mean and standard deviation from the census data. Overcrowding was reverse coded such that the direction of all measures indicate a better social environment. The four measures were summed then divided by 4 assuming equal weights for all four measures. This index was developed using data for cities (L1AD), the same method was applied to create the index at sub-city (L2) level. The higher the index the best social environment.
