Help us find the world’s electoral boundaries!

We're looking for the digital files which show the boundaries of electoral districts — and we'd like to find them for everywhere in the world.
Do you know where to look online for the files showing your country's electoral boundaries?

Why we're collecting boundaries

When people make online tools to help citizens contact their local politicians, they need to be able to match users to the right representative. The boundaries of electoral districts are an essential piece of the data needed to do this. However, there is a great variety of organisations responsible for maintaining electoral boundary files across different countries. This means there is little standardisation in where they are published. As part of mySociety's commitment to the Democratic Commons project, we'd like to be able to provide a single place where anyone can find these boundary files easily.

How you can help

This Every Boundary survey asks you for the URLs where we can find electoral boundary files online. Search online to locate a source for your country's electoral boundaries. We're interested in boundaries of any level from national to local. If you need more help with this step, see the FAQ section.

1. Find your country in the survey list, below. You can use the search box or scroll to find it. 2. Click one of the boxes marked ‘add' (the columns relate to national, regional or city-level boundaries, in that order). 3. You'll be asked to log in via Google or Facebook. 4. Once logged in, you'll be taken to the survey page for your chosen country. From the dropdown at the top of the page, you can change the level of legislature or the country, if required. 5. The survey asks for the URL where the boundary data can be found, and some further questions to help us understand more about them, their format and license information. Please do not worry if you cannot answer the questions with total confidence, but do answer them as best as you can.
