From marriage records of a Northern Portuguese parish for 1900–80, endogamy and exogamy rates were calculated for birthplace and residence in order to analyse the effect of industrialisation on the population structure after 1940. Marriages that were endogamous relative to birthplace decreased between 1940–49 (58·9%) and 1988 (20·5%), while exogamy increased. Exogamous marriages in which people came from outside the municipality (51·92%) were greater than those of the surrounding region (42·04%). After industrialisation, the pattern of marriages changed for residence, with an increase in the number of individuals who came from the district to work in the factories and married. Industrialisation advanced the start of exogamy which, for most Portuguese populations, began later, in the 1960s.
