These statistics are difficult to put in to terms of "identify as LGBTQ+". The 3.2% of individuals who identify as gay or lesbian and the 11.9% who identify as bisexual would be considered identifying as LGBTQ+, however that only accounts for 15.1%. It is unclear to say that the 9.0% of individuals who responded as other or questioning would identify as LGBTQ+, therefore you cannot conclude that they are also in the final statistic. This would mean that according to your statistics, 1 in 4 students do not identify as LGBTQ+, and rather it is only certain that 15.1% do. Thanks!
