It’s been long recognised that families are more willing to move when his job dictates than hers. Traditionally, theories as to why this happens include gender roles which dictate that a man’s job is more important than his female partners or the fact that men on average have had greater earning potential – so families simply follow the money. However, a new University of Minnesota study by Alan Benson published in Demography suggests a 3rd reason may be the root cause – men are more likely to pick jobs that require presence in a sector-relevant location; women pick jobs that are less ‘geographically clustered’. Male dominated sectors such as engineering or oil and gas are based in certain hubs whereas teachers, administrators and healthcare workers are in demand everywhere. But why are women drawn to ‘geographically dispersed’ jobs? Early expectations may play a big part. If people assume that families will put a male breadwinner’s job first, it makes sense for women to be drawn towards fields that give them mobility.
