Ireland 2020 General Election HEX Maps

Ireland has a great single transferable election system. It means that every vote is meaningful even for smaller parties and candidates. It also means mapping the results is difficult. As each constituency has more than one seat, ranging from three to five.

One way to map the results is to have the constituencies split up. Either geographically, so split into parts based on how many seats it has. Or into equal sized pieces, like hexes.

Since I had not seen an election hex map for Ireland yet. I thought I would attempt to make one for the February 2020 General Election.

Constituencies split into equal sized parts based on number of seats.

The hexes and split files can be found on GitHub:

Geometries were split using the tutorial from Paul Ramsey:

John Snow Pub

I was once at an OpenStreetMap conference where 6 out of the 8 talks in one day had an image of the John Snow Cholera Map. And no surprise, it is an excellent, relatable, and interesting early example of GIS. The spatial relationship is unmistakable.

The site of the Broad Pump is now the location of a pub called the “John Snow”, which is well worth a visit if you are in London.
