Guatemala Paper of the Day (Violence in a Random Sample of Households)

From a paper (the third one in the list) by Dinesen et al., two interesting things, (1) the positive relationship between prevalence of violence and household income, and (2) more violence in households in urban areas. 

I grew up in San Marcos, where the level of violence is lower (Figure 1). 

An except from the methods

Data from a cross-sectional victimization survey conducted in 2008–2010 in Guatemala were analyzed. Two-stage proportionate sampling was used in the survey. Households (n = 1 300) were randomly sampled within a random sample of communities (n = 118) in five administrative departments. The survey collected information on the six-month vio- lence exposure of 6 335 individuals.
