Mapping City Gayborhoods


The Pudding has mapped out gay neighborhoods in 15 different cities. The map plots businesses tagged 'gay bar' and data on where same-sex unmarried partner households and same-sex married joint tax filers live, in order to determine the gay neighborhoods in each city. The Pudding has also mapped out the differences in where same-sex female couples live and where same-sex male couples live.

Men are from Chelsea, Women are from Park Slope includes three maps for each of 15 of the USA's largest cities. For each city one of the maps provides a choropleth view of where same-sex couples are more likely to live. The other two maps shows where same-sex female couples are more likely to live and where same-sex male couples live.

The Pudding has also provided a descriptive overview of the gayborhoods in each of the 15 cities. This includes information on such things as where Pride parades have been routed and where gay bars have tended to be sited. It also includes the first hand accounts of local residents about local gay friendly and gay unfriendly neighborhoods in the featured cities.


Another way to determine a city's gay friendly neighborhoods might be to see where people go after Pride. Last year Carto undertook an interesting geo-data investigation into where people go after taking part in New York's Pride parade. A Map of Where People Went After the NYC Pride Parade uses pick-up and drop-off data from New York's yellow taxis to determine what people did after New York's 2018 Pride parade.

Using data from Sunday June 26th, 2016 (the date of last year's Pride in New York) Carto isolated all the taxi pick-ups in the Pride parade area between 4-8pm (when the parade was winding down). They then created a map of all the drop-off points from these pick-ups, to see where people were going after Pride. Carto used a DBSCAN clustering algorithm to identify locations with a high density of drop-offs.

Major transit hubs feature quite prominently, presumably for people heading home, Areas with popular gay bars also appeared to be popular destinations. Locations around hotels is another take out from the mapped data.
