Guide to Replication files for "The role of childlessness in changes in cohort fertility: Cross-national comparisons of countries in Europe, East Asia, and North America" by John Ermisch (DemRes 55(15): 451-464. doi::10.4054/DemRes.2026.55.15) The excel worksheet 7434 Replication Table 1 provides the data for the Figures and the calculation of the decomposition of cohort completed fertility (CCF) change for each country in Table 1. Decom_countries_replication.dta is a STATA file which contains the country data in Table 1 and the weights for computation of weighted means. decomp_means.do is a STATA do file which calculates key correlations and the weighted means and robust standard errors for them using Decom_countries_replication.dta. Decomp_means-corr.log is the output file from running decomp_means.do.
