List of communities in Puerto Rico

In Puerto Rico, there are 78 municipalities and 902 municipio subdivisions made up of 827 barrios and 75 barrios-pueblo.

[a] There are also a number of subbarrios and communities.

The following is a list of the 902 barrios, some of the subbarrios, including the 40 subbarrios of Santurce, which is a barrio of San Juan and a few communities (comunidad, on the U.S. Census) arranged in alphabetical order.

[1] Barrios (which for US census purposes, are roughly comparable to minor civil divisions)[2] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).

The types of sectores may vary, from normally sector to urbanización to reparto to barriada to residencial, among others.
