Analysis of data from the Family Financial Survey, included in the Spanish Statistical Plan, shows that parents aged 50-75 living together with children over 30 in the family home has an adverse effect on the well-being of mothers, especially if they are adult male sons.
In Southern European countries, more than 40% of adults aged 25-34 live at home with their parents and the average age of leaving the family home is 29.8 years. Apart from economic aspects, the cultural contexts of Mediterranean countries seem to explain these results, as they are traditionally characterised by stronger family ties and a less equal division of household labour.
