The Hajnal line links
Saint Petersburg,
Russia and
Trieste,
Italy. In
1965,
John Hajnal discovered it divides
Europe into two areas characterized by a different levels of nuptiality.West of this line, the average age of women at first marriage was 24 or more, men 26, spouses were relatively close in age, and 10% or more of adults never married. East of the line, the mean age of both sexes at marriage was earlier, spousal age disparity was greater and marriage more nearly universal. Subsequent research has amply confirmed Hajnal's continental divide, and what has come to be known as the 'Western European marriage pattern', although historical demographers have also noted that there are significant variations within the region.
