The study finds that .35% of adults identify as transgender. While this rate is much higher than in the past, the only reason why so much public concern is devoted to such a small group of people is that liberals always need a fresh crusade.
Demographically, transgenderism is largely a white thing. While the percentages of transgenders that are black or Asian are about what you'd expect from the racial composition of California, the white rate is much higher, and the rate for Hispanics is much lower. To be specific, whites are 4.8 times more likely to be transgender than Latinos. You tell me why the gap is so big.
Slightly more than half of transgenders start out as life as males. The plurality (46%) now say their gender identity is transgender. The next largest group (32%) identify as female, so this shows a tendency for male-to-females (MtF) to be the clearest about who they are.
Compared to cisgenders, transgenders have much higher numbers of gays and lesbians (20%) and bisexuals (45%), so in terms of sexual orientation, transgenders are a very messy group.
Other stats not specified here indicate that transgenders are more likely to be: poor, less educated, and psychologically and physically unhealthy. They suffer from high rates of emotional disturbance, depression, disability, and positive HIV status.
This reminds me of the recent study of homosexuals which showed genetic correlations with psychological difficulties and substance use.
The picture that emerges is of people who perhaps have a high number of mutations that disrupt the type of development that aligns one's anatomical sex with his gender identity and his sexual orientation--an alignment which makes an individual likely to be reproductively successful. In addition to this, other brain systems responsible for psychological health are also disrupted.
