The estimation sample includes Waves 2 and 3 (interviews 2012–2014) for children born between March 2011 and December 2012.
Notes: DiD estimate shows the DiD coefficient from regressions of the given variable according to Equation 1. Robust standard errors in parentheses. Significance levels: *p < 0.10, **p < 0.05, ***p < 0.01.
