Gay and lesbian couples have tied the knot 48 times in Birmingham since civil partnerships began last December.
But the number of gay marriages is far fewer than in other parts of the country, even though Birmingham is the largest local authority.
The Civil Partnership Act, which formally recognises gay and lesbian relationships, came into force on December 5.
There were already 3,648 civil partnerships in England and Wales by the end of January, according to the Office of National Statistics - 2,510 involving men and 1,138 involving women.
They included 48 in Birmingham, 36 in Staffordshire and 31 in Warwickshire.
The largest number of partnerships was in Brighton and Hove, where 126 couples were took part in the ceremony.
There were 121 civil part-nerships in Westminster, 76 in Hampshire and 75 in Kent.
Birmingham also had fewer ceremonies than cities such as Leeds, which had 51, and Manchester, which also had 51.
The Act created a new legal relationship of civil partnership, which two people of the same gender can form by signing a registration document.
A partnership gives partners a legal right to employment and pension benefits and recognition for immigration and nationality purposes, in a similar way to a marriage. ..SUPL:
