Table 3.

Models of change in desired family size (Coombs Scale) from baseline to follow-up predicted by change in time to collect firewood (hours to travel, gather, and return home). Effect estimates with t-statistics in parentheses from regression models with individual level fixed effects. Women aged 15–33 in Chitwan, Nepal at baseline.

Control measures are wave specific and should therefore be interpreted as change measures.
