I wrote most of this post in another thread, but it may be useful here:
Note that there are various angles of this that may not be fully covered by “LGBTQ+ friendly” or not. In particular, the friendliness to various letters of the acronym tends to vary (usually LBf > GBm > Tm >> Tf). But also consider that the following aspects can vary:
- Social scene and acceptance on campus. Most ratings here will be at least somewhat subjective. This includes survey ratings like LGBTQ-Friendly Colleges | The Princeton Review and LGBTQ-Unfriendly Colleges | The Princeton Review that aggregate subjective opinions of respondents.
- Social scene and acceptance nearby off campus. Most ratings here will be at least somewhat subjective.
- Campus policies (this is what https://www.campusprideindex.org/ mostly measures).
- State laws and policies on the subject (look at state level politics, such as the state legislature and governor, rather than national politics like US senate and presidential elector election results). Movement Advancement Project | Snapshot: LGBTQ Equality by State can be a useful list, although changes in the state level politics over the next few years can change the laws and policies while a student is in college.
