Unique observation from the data of Electrol Roll in Tamil Nadu

Very interesting data. I just noticed the unique demographics of the electoral roll of the Tamil Nadu state in south.

Total electorate 45.9 million .

men 23.0 million .

women 22.8..Million.

Transgender 844.

I have seen some very interesting data at different times but have never seen the count for transgender separately listed . I wonder where is the count of transgender in USA.
