^aAsset data can be missing due to one of the following: non-response (all waves), migrated outside study villages in Department of El Progreso (1987, 2002), migrated outside Guatemala (all waves); ^bAvailable for 2041 cohort members; ^cAvailable for 2169 cohort members; ^d from harmonized wealth index closest to birth; e Attained schooling for alive and not included in study wave from latest wave of availability (N; 2015–16: 232, 2017–18: 122) and for those dead between 2015 and 16 and 2017–18 (N = 15); Continuous variables are displayed as mean ± standard deviation (if normally distributed) or median [25th percentile, 75th percentile]. Categorical variables are displayed as percentage (%). Number of households with cohort members who were alive and for whom asset data were available: 617 (in 1987), 820 (in 2002), 1075 (in 2015-16) and 1145 (in 2017-18)
