Married couples are less likely to split up than those who live together, according to the Office for National Statistics.
Analysis of Census results found that four-fifths of spouses who were married in 1991 were still together a decade later, compared with three-fifths of cohabiting couples.
Older couples and those with children were more likely to stay in the same relationships, the independent statistics body said.

No surprise really. Living together: all the disadvantages of marriage and none of the advantages.
