The number of same-sex civil partnerships taking place in the United Kingdom dropped 55 percent in 2007 from 2006 – likely reflecting a decline in pent-up demand since the law took effect in December 2005.
The figures were gathered by the Local Government Association from officials in 40 localities.
The Office of National Statistics has recorded a similar drop-off.
More than 16,000 couples formed a civil partnership in 2006 but only 4,060 did so in the first half of 2007, agency records show.
However, the total number of civil partnerships to date exceeds government estimates issued when the law took effect. Officials had expected to see a maximum of 22,000 partnerships by 2010.
