Abstract The geographical distribution of age at menarche in great Britain is analysed in two successive generations. It appears that the variances for age at menarche are equal throughout the country. The means, however, show significant and complicated patterns of regional variation. In the southern and eastern parts of the country, menarche was earlier than in the northern parts in both generations. This patterning is not due to social class differentiation. Except for the sparsely populated areas in northern and western Scotland and for the extreme south-western parts of England and Wales all areas show evidence of a decline in age at menarche from the mothers' to the daughters' generation.
