It is confirmation of what many weary commuters have secretly suspected.
Research has found that stay-at-home mothers are happier than those who go out to work.
The survey said that if staying at home with the children were counted as a job, it would rank as having happier workers than any other trade or profession.
Only one in seven stay-at-home parents say they are dissatisified with their role, a level of unhappiness that is less than half that found among civil servants or salesmen and women.
The survey, carried out for UK insurance group LV=, asked more than 3,000 to say whether or not they were satisfied with their lives. The ratings recorded are the percentage who indicated they were not unhappy with their lot.
