The Human Rights Campaign examined 137 municipalities, grading each area's laws and policies for LGBT individuals.
Green municipalities shown on the map scored a higher "municipal equality index" out of 100 possible points.
HRC used a rating system based on 47 criteria in six categories: non-discrimination laws, relationship recognition, municipal employment practices, city services, law enforcement and municipal leadership. Localities could also earn up to 20 bonus points for programs not applicable to other areas.
Each area's final score assesses laws and practices of the locality, not necessarily the quality of life.
