Forty-seven cities scored 100 on the Human Rights Campaign's (HRC) fourth annual Municipal Equality Index (MEI), which measures a city's support for LGBT rights.

"While this has been an historic year for equality, we are constantly reminded of just how far we still have to go,” said HRC President Chad Griffin.. “In too many communities, LGBT Americans continue to face barriers to equality, overt discrimination, and even violence. We believe those challenges make full equality and strong legal protections all the more important, and today's report makes clear that hundreds of local communities throughout all 50 states wholeheartedly agree.”

Cities scoring perfect marks have increased steadily, starting with only 11 in 2012 and increasing to 38 in 2014.

“Across the nation, cities and towns are leading the way on equality for millions of LGBT Americans,” Griffin said. “This year, a record number of communities have earned top scores in our Municipal Equality Index because they’ve extended fully-inclusive benefits and protections to LGBT people and their families. What makes this progress especially remarkable is that these cities and towns are often going above and beyond state and federal laws to ensure LGBT residents and visitors are protected and treated equally.”

Detroit and Las Vegas were among the cities earning a perfect score for the first time.

Other cities with a perfect score include Phoenix, Tempe, Tucson, Cathedral City, Long Beach, Los Angeles, Palm Springs, San Diego, San Francisco, San Jose, West Hollywood, Orlando, St. Petersburg, Wilton Manors, Atlanta, Chicago, Bloomington, Davenport, Iowa City, Louisville, Baltimore, Boston, Cambridge, Worcester, East Lansing, Minneapolis, Saint Paul, Kansas City, St. Louis, Missoula, Jersey City, New York City, Rochester, Yonkers, Cincinnati, Columbus, Portland, Philadelphia, Providence, Austin, Dallas, Bellevue, Olympia, Seattle and Madison.
