Age at menarche in rural France.
Data upon age at menarche have been collected among 254 schoolgirls of a relatively endogamous rural population in central France. The median age at menarche estimated by probits was 13.05+/-0.18, SD1.42. This accords well with results obtained from urban samples in the years 1965-68. Both rural and urban samples give a median age 0.5 year earlier than date from a national survey performed in 1950.
