A strong relationship was found between the proportion of childless women and the gross reproduction rate with a time-lag of 10 years. The respective regression equation seems, however not to be stable in time. The proportion of married women aged 30 - 34 having no children below age 16 might also serve to estimate the proportion of childless women.polinfo:eu-repo/semantics/openAccessArtykuł
