A multiple regression analysis was undertaken of menarcheal age in girls admitted to the University College of Swansea between 1959 and 1965. The estimates of mean menarcheal age are concordant with data from other parts of Britain for girls of corresponding birth years. A significant secular trend to diminishing menarcheal age is shown, at a rate that is concordant with, or possibly slightly higher than, the rate over the last century.
