FA is a binary variable that indicates whether or not the households of the municipalities had receive any payments of the Familias en Accion program in June 2002, the start date of the survey under study. Households in some of the municipalities started to receive payments for longer than 6 months before the baseline interview, but for most of them it was just six months before the interview. The little time that the program has been operating should be taken into account when analyzing this variable, especially when the dependent variable is height for age or leg length as they.
