Lavapiés, Usera, Carabanchel, Vallecas, Orcasitas and Villaverde have a high percentage of immigrant residents but also some of the lowest percentages of people with the right to vote. In Lavapiés, the most multicultural neighbourhood in Spain, up to a third of residents hold a foreign passport and, even if they're registered here and pay their taxes, they still don't have the right to vote in regional and national elections.
