The data used in this work have been collected from clinical histories of women who have been examined at the Ginecology and Obstetritian Service of the Santa cruz y San Pablo Hospital of Barcelona. The sample consisted of 12,803 Spanish women, born between 1909 and 1965, by regions of birth. The method used is retrospective. The maximum menarcheal age in Spain (13.91±0.049 years) is found among those women born between 1925 and 1929 and the minimum menarcheal age (12.92±0.036 years) among women born between 1955 and 1959; so in an interval of 30 years, a reduction of almost a year (11.88 months) has taken place in age at first menstruation. This means a reduction of almost four months per decade. These differences are significant (p=.0000). The higher menarcheal age appears in the Northern Zone, due to the influence of Galicia in the sample (Galicia being a depressed zone with a great emigration rate). The earliest menarcheal age appears in the Mediterranean Zone due to the great percentage of catalan women (Catalonia being a region with a higher socioeconomical level). It is also to be observed that although the menarcheal age has decreased in all the zones, it has done so more dramatically in those zones which had higher values at the beginning. Although the secular trend of reduction in the age at menarche varies greatly from region to region, it may be considered that, in general, the socieconomic conditions have been the decisive factor in the change in physical maturation of Spanish women
