The proportion of children adopted by gay couples in Nottinghamshire is well above the national average, according to new figures.
Last year, one in nine children was placed in a same-sex household, the county council said.
Government figures show the national average is one in 15 and in Derbyshire it is one in 20.
Both the authority and gay couples said it was important to dispel old myths about who could adopt.
There are more than 800 children in care in Nottinghamshire. Last year, 92 adoption orders were granted, compared with 40 in the previous year.
