The population is distributed in the island group of Romblon just south of Luzon with concentrations in Romblon (20,510), San Agustin (19,660), Cajiodiongan (13,800), and Look (13,420). The total population ranges to about 147,000 (NSO 1980).

       The island is well-known for mountainous topography; most of the population are concentrated along the peripheries of the island, with the mountainous interiors practically devoid of inhabitants. There is a general absence of large productive agriculture, and urban centers. Romblon is the port of call and collection point for copra which is the only significant production of the people. There is a modest production of marble which is the richest mineral resource of the island. There are some livestock which are supplied to Manila. Domestic fishing is prevalent.
