Notes: Samples include balanced panels of children with valid anthropometric measurements in each age group. Age controls are binary indicators for agein-months at measurement; cluster level time trends are binary indicators for each cluster in 2012. Migrant household is defined as a household with at least one migrant in the U.S. in three of the four years 2005-08 for children under three years old in 2008 and three of the four years when children three to six years old in 2008. All observations weighted for attrition using inverse probability weights constructed from models predicting re-survey as described in Appendix Note. Standard errors estimated allowing for clustering at the community level in parentheses. *** indicates significance at p<0.01, ** at p<0.05, and * at p<0.10.
