Methodology is different, but according to the last National Health Survey published by Brazilian Statistical Office in 2022 bringing 2019 data, 2.9 million Brazilian adults (1.8%) declared they were homosexual or bisexual.

Amongst those between 18-29 y/o, the number is considerably higher, at 4.8%. Same for people with a college degree (3.2%) and with the highest income bracket (3.5%). The highest rate was in Southeast (2.1%) and the lowest in Northeast (1.5%). Amongst women, 0.9% declared they were lesbian and 0.8% bisexual; amongst men, 1.4% gay and 0.5% bisexual.

It was the first survey they conducted on that matter and it was very comprehensive (a sample of 108,525 households). They're studying already some modifications, such as the use of words "gay" and "lesbian" instead of "homosexual" and there's a project to collect data on trans people on the next editions.
