The UK's two million stay-at-home parents - the great majority of them mothers - were recorded in the report as "homemakers". They scored 87.2 per cent in the happiness ratings. The others in the top five were those working in: hospitality and events management - 86.3 per cent; creative arts and design - 84.4 per cent; the charity sector - 83.9 per cent; leisure, sport and tourism - 83.7 per cent.
The least satisfied were working in marketing, advertising and public relations, with a happiness rating of 53.8 per cent. The others in the bottom five were: police and security officers - 59.4; salesmen and women - 67.4 per cent; civil servants - 70 per cent; shop workers - 70.8 per cent.
The report said: "Homemakers are happier than people working in any other occupation, but they work double the hours most people think." The findings reinforce the results of large-scale research on well-being carried out by the Office for National Statistics, which has shown that stay-at-home mothers believe their lives are more worthwhile than their counterparts in work.
Government surveys have also shown that more than a third of mothers who go out to work would like to give up their jobs and stay at home with their children.
Laura Perrins, co-editor of the Conservative Woman website, said: "What this survey confirms is how satisfying the vocation of raising children at home, and all the work that this entails, is. Mothers who do this know what a responsible job raising children is. It is a shame our [British] Government does not share this view."
