LGBTQI+ scene
San Francisco has the highest proportion of LGBT population in the US (~15% city, ~6.2% metro per Gallup 2015). Scene split in three poles: Castro (classic, social), SoMa (leather, circuit) and Mission (queer Latino, alternative). Total offer dropped from peak 118 gay bars in 1973 to 33 in 2011. Still one of the world's densest LGBTQI+ ecosystems.
