Estimates recently published in the ONS’ survey on ‘Families and Households: 2017’ show that the number of families in the UK have increased by 8.1% over the last ten years to 18,997,000.
14 million dependent children are currently estimated to be living in families in the UK. It is, however, families with no children or no dependent children that were more common.
Married couples and those living in civil partnerships are the most dominant group, with civil partnerships driving the growth of this group, increasing by 66.7% (versus 4.8% for married couples) particularly at younger age groups.
Some 6.6 million (40%) 15-34 year olds live with their parents. The ONS suggests that the larger numbers of young adults tending to stay at home for longer may be explained by staying in education and training for longer, formalising relationships and having children at older ages, and increased costs in renting or buying a home.
