“More than one in five young Americans (18-29 years) identify as LGBTQ (22%). One in ten people ages 30-49 (10%), 6% of people between 50 and 64 years, and 3% of people 65 years or older identify as LGBTQ. Twenty-four percent of Gen Z Americans (aged 18 to 25) identify as LGBTQ.”

Strangely percentages are a bit off though.

Ah yes, you’re right. I read it as “% ot total population of that specific age group” and I guess that is what is meant, but it is not very well phrased indeed.

What makes you think 50%? The highest percentage in one particular age group is about 28% meaning the average of the whole population is of course much lower.
