There is not that much Family Diversity:
> Chester - the extent and importance of family diversity has been exaggerated - the nuclear family has changed to the neo-conventional family, in which both spouses work and the division of labour is more equal and shared - most people still marry, have children and live in a neo-conventional family
> more people cohabit, but this is a stepping stone
> single-person households are either elderly widows or young or divorced people that aspire to live in a nuclear family
