      During the twentieth century there has been a great change in the lives of women. 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, of whom four or five 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 chance and 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 and can be expected to live another thirtyfive years and is likely to take paid work until sixty.

     This important change in women's life has only recently begun to have its full effect on women's

economic position. Even a few years ago most girls left school and took a fulltime job. However, when

they married, they usually left work at once and never returned to it. Today the schoolleaving age is

sixteen, many girls stay at school after that age, and though women marry younger, more married women

stay at work at least until shortly before their first child is born. Very many more afterwards return to full

or parttime work. Such changes have led to a new relationship in marriage, with the husband accepting a

greater share of the duties and satisfactions of family life.
