John Hajnal (original) (raw)
- John Hajnal 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, 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. (en)
- John Hajnal (26 november 1924 - 30 november 2008) is een Brits wiskundige. Hajnal ontdekte in 1965 dat er door Europa een fictieve lijn loopt (tussen Triëst en Sint-Petersburg), die Europa verdeelt in een gebied waar de huwelijksleeftijd relatief laag ligt (ten oosten van de lijn) en een gebied waar de huwelijksleeftijd extreem hoog ligt (ten westen van de lijn). De hoge huwelijksleeftijd ten westen van de Hajnallijn staat waarschijnlijk in verband met het . Een andere bevinding was dat de lijn ook een scheiding vormt tussen verschillende samenlevingsverbanden. Ten westen van de lijn is het de gewoonte in samen te leven, terwijl men aan de oostelijke zijde in samenleeft. (nl)
