A total of 42,778 same-sex couples in England have entered civil partnerships; only 1,007 of those have sought dissolutions. Of late, however, there has been an upward trend for termination of both same-sex and different-sex couple relationships. From SoSoGay:
A new report released by the [British] Office of National Statistics this week has shown that divorce figures in 2010 have risen. It is thought that the current economic climate is putting financial pressure on couples, leading to breakdowns in relationships and a rising number of couples getting divorced. The divorce statistics for married couples have been reflected in those of same sex Civil Partnerships; there has also been a rise in the number of dissolutions...
[Civil partnerships became available for same-sex couples in late 2005.] [F]emale partnerships [are] more likely to end than male ones despite the fact that up until 2010, more men formed civil partnerships than women. Thomas Duggins is Solicitor in the family team at Charles Russell LLP. ‘Up to the end of 2010, 62% of dissolutions have been to female couples, despite the fact that only 44% of formations were to female couples,’ he told So So Gay. ‘The evidence suggests therefore, that female civil partners are more likely to dissolve their partnerships.’ This trend has also been seen in other countries where same sex unions are possible.
Duggins attributes this variation to the age difference between male and female partnerships. ‘Statistically, male civil partners are on average older than females when they form a civil partnership, and this may explain the difference in dissolution rates. It could be that entering the civil partnership when older means that it is less likely to fail, because the parties have known each other for longer. Certainly, the statistics show that the mean age at dissolution is similar or lower than the mean age at formation, which suggests that younger couples are more likely than older couples to dissolve their partnerships.’ Which may indeed mean that age is a more important factor than gender, in the stability of civil partnerships.
