[3][4][5] Barrios (which are, in contemporary times, roughly comparable to minor civil divisions)[6] in turn are further subdivided into smaller local populated place areas/units called sectores (sectors in English).

Salto was in Spain's gazetteers[11] until Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became an unincorporated territory of the United States.

In late May 2019, Saltos and many other areas in various municipalities suffered flooding, felled trees, landslides and closed highways when Río Culebrinas flooded.
