When it comes to maps of the results of Australia’s same-sex marriage referendum (or, to be more precise, postal survey), it’s a mixed bag. At the official end, the Australian Bureau of Statistics provides infographics, but no maps. The Sydney Morning Herald provides a map of the results by district (see screenshot above), but it’s boolean (yes/no) rather than a choropleth or heat map. For that, you’ll want to look at The Australian’s interactive map (they also have a map showing yes/no by constituency, centred on Sydney, whose western districts voted against the most).

Finally, this map by “lunatic map maker” Matthew Isbell is making the rounds; I want to make sure he’s correctly attributed.

The number of same-sex marriages in the United States is not directly tracked. But a new Treasury Department research paper has been able to come up with a count of same-sex marriages by looking at jointly filed tax returns; the New York Times story is accompanied by a nice interactive map of such marriages by zip code.
