If I were to guess, my estimate would be that there are over a thousand Americans, Canadian, and other expats living in the Cayo District, Belize. You see them all the time.
If you walk the streets, if you go to restaurants, you go to the bank and to the post office, you will definitely run into some type of expat, whether they’re Canadian, from the US or European--you'll definitely see that. And these are the ones who actually live here. In addition to that, there are all the tourists.
A lot of the people visit here who are astounded by how many foreigners actually see here. This is not common in other countries in Central America. I've been to Panama, Honduras, El Salvador, Guatemala, and you only see foreigners if the area is touristy. If you went to Tikal, of course, in Guatemala, you will see foreigners there. But here in Cayo, it's different; you'll expats and tourists practically everywhere. You’ll see them in Belmopan, San Ignacio, Santa Elena, Spanish Lookout, and along Hummingbird Highway.
Most of the expats don't live in towns. Rather, they live in areas around the towns of San Ignacio and Santa Elena, in places like Bullet Tree, Santa Familia, Billy White, Cristo Rey, along Hummingbird Highway, United Ville; anywhere along the highway between San Ignacio and Belmopan, you'll find them.
