Earlier this month, the Mayor’s Office of GLBT Affairs released a comprehensive report [PDF] on lesbian, gay, and bisexual health in the District of Columbia.

No, you aren’t missing something in the title of that report: where’s the ‘T’?

The report’s weaknesses have been picked apart — poor methodology, lumped together demographics and an underrepresentation of African-American men and women — but there isn’t a problem so startling as the report’s complete lack of transgender data. After the release of the report, the DC Trans Coalition sent a letter to the Mayor to register its disappointment with the “continued invisiblization of our communities” which “contributes to the widespread ignorance about trans people.” Gathering data on the transgender community can’t be the easiest job in the world. But for an agency who has the job of bridging the gap between the government and the transgender community, the report represents a real failing.

Metro Weekly reported that Christopher Dyer, director of the Mayor’s Office of GLBT Affairs, couldn’t comment on the omission of transgender data, but that such data is “certainly something that we can look into possibly including in 2010.”
