John Hajnal[needs IPA] FBA (born Hajnal-Kónyi, [ˈhɒjnɒl ˈkoːɲi]; 26 November 1924 – 30 November 2008), was a Hungarian-British academic in the fields of mathematics and economics (statistics).
Hajnal is best known for identifying, in a landmark 1965 paper,[1] the historical pattern of marriage of northwest Europe in which people married late and many adults remained single. The geographical boundary of this unusual marriage pattern is now known as the Hajnal line.
