Great article from the Baltimore Sun
Maryland's appeal is bolstered by the reputation of the Baltimore City Circuit Court, which was the first in the state to grant a second-parent adoption to a gay partner. It is well-known in certain circles as a friendly and efficient place for gay couples to complete adoptions and has, as a result, become a popular jurisdiction for such proceedings. Gay families also say they are drawn to Maryland because of the climate of acceptance they've found in the state.
Almost 4,400 children were adopted in Maryland in 2001, the most recent year that complete figures were available, according to the U.S. Children's Bureau. There are no figures for how many of them were adopted by gay parents. But a recent study found that Maryland is a leader in the total number of adopted children living in gay or lesbian households, ranking eighth among the states.
Using the 2000 Census, researchers from the Williams Institute on Sexual Orientation Law and Public Policy, a UCLA think tank, and the Urban Institute, a nonpartisan research organization, determined that 2,142 of the 32,269 adopted children in Maryland were living with gay couples.
