　　The greatest recent social changes have been in the lives of women.During the twentieth century there has been a remarkable shortening of the proportion of a woman’s life spent in caring for the children.A woman marrying at the end of the nineteenth century would probably have been in her middle twenties，and would be likely to have seven or eight children，four or five of whom lived till they were five years old.By the time the youngest was fifteen，the mother would have been in her early fifties and would expect to live a further twenty years，during which health made it unusual for her to get paid work.Today women marry younger and have fewer children.Usually a woman’s youngest child will be fifteen when she is fortyfive years and can expect to live another thirtyfive years and is likely to take paid work until retirement at sixty.Even while she has to take care of children，her work is lightened by modern living conditions.
