The percentage of UK residents in one family married households dropped from 50 per (25.3 million) to 44 per cent (24.4 million) in the decade between 2001 and 2011. Meanwhile the percentage of people cohabiting increased by two per cent, from ten per cent (5.4 million) to 12 per cent or 6.5 million.
Single parent households rose by just one per cent in the same time period – from 11 to 12 per cent, or 6.5 million, in 2011.
The percentage of people living in single person households did not change over the ten years, staying at 13 per cent (6.5 million).
All the figures are derived from the 2011 UK census and refer to households in which at least one member is under 65 years of age.
