During the 20th century there has been a great change in the lives of women.A woman marrying at the end of the 19th century probably has been in her middle 20's and would be likely to have seven or eight children.By the time the youngest was 15,the mother would have been in her early 50's and would expect to live a further 20 years,during which chance and health made it hard for her to get paid work. Today women marry younger and have fewer children.Usually a woman's youngest child will be 15 when she is 45 and she can be expected to live another 35 years and is likely to get paid work until 60.

However,when they married they usually left work at once and never returned to it.Today the school-leaving age is 16,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.Many more return to work later.Such changes have led to a new relationship in marriage,with the husband accepting a greater share of the duties of family life.
