Geography of Hate: Geotagged Hateful Tweets in the USA.
While the US population is heavier on the right side of the map, it is still surprising to see the density of hatred - as expressed in tweets.
The map is interactive, and that is where the interesting bits of data are. For homo phobia... Two of the darkest area of red: Iowa City, Green Bay. That seems a bit surprising.
On the west coast, county near Reno and Portland are darker (though Portland a lot more, and that is surprising).
You can also switch the category. For racist content, Indianapolis, Iowa City (again) and the area around Minneapolis stand out.
The data is biased in that it is just tweets and people on twitter are not a uniform reflection of the populations in that area. It is interesting to look at this data and reflect.
