There are a large number of foreigners in Quintana Roo (a state in the Yucatan Peninsula that has Cancun, Playa del Carmen, and Tulum; generally called the Riviera Maya).
In Merida (a city of over a million inhabitants in the state of Yucatan), there is also a substantial number of expats. The Progreso area, which is east of Merida all the way up to the coast has thousands of expats as well. In Celestún, a village of about 7,500 where I live, about an hour west of Merida, we probably have twelve to fourteen non-Mexican residents who live here year round. In the winter, that number rises to about thirty to thirty-five foreigners. There are very few expats living here in Celestún but there are going to be more because of the condo projects that are planned for this area. We will end up with about one hundred more buildings, which will bring more people, more employment, and more exciting things to do.
