Yes. That figure is actually based on a US Census count.
Yea I figured that BUT the "report" referred to was related to Texas not the US.
Not to mention Prop. 2 is about Texas only.
This sounds like an alarmingly high number, but consider that there are 60 million coupled households in the US, so only 1% of coupled households are homosexual. About what you would expect for under 2% of the population.
