The economy is mainly based on farming and fishing, but tourism — especially for diving — is gradually becoming more important.
Nearby islands are Mindoro to the west, Marinduque to the north, Masbate to the east, Panay and Boracay to the south. Mindoro, Marinduque and Romblon are all in the administrative region of Mimaropa, which in turn is part of the Luzon region.
Carabao Island, also known as the municipality of San Jose, or locally as Hambil, is off the southern tip of Tablas and is close to the highly-developed resort island Boracay. It has fine beaches and is being developed for tourism.
The capital, Romblon Town, is on the north coast of Romblon Island. Alacantra, on the east coast of Tablas Island, has the airport.
If you are wondering why locals in each town in Romblon have last names beginning with the same letter (e.g. R in Romblon town, thus there are the Romeros, Ramoses, Reyeses, etc.), this is a result of a colonial decree that mandated Filipinos to adopt a surname. Historically, the people in Romblon do not have surnames, and in 1849, they were required to adopt one from an official catalog for taxation and record-keeping purposes; the decree also states the inhabitants of each town must have a surname beginning with the letter assigned to each settlement by the colonial administrators. In Romblon, it was strictly enforced. You might know where someone in the province came from by just taking the first letter of their last name.
Romblon's name derive from a corruption of the Romblomanon word nagalumyom, referring to the act of how a hen sits over its eggs, but local historians argue it is from Spanish ronblon (screw) or doubloons.
While administratively part of the Tagalog-majority Mimaropa region, the people of Romblon are more closely related to those in the Visayas than to the Tagalog. People of Romblon belong to the Romblomanon, Inonhan and Asi ethnic groups and have their own languages, that are part of the Visayan subgroup.
The archipelago's economy is mostly dependent on agriculture and fishing. Also, another source of local income is Italian-quality marble extracted from the islands' mountainous interior. Ecotourism is an emerging industry, but tourists are few and far in between. Most items sold on the island has to be shipped from Luzon or Mindoro, and can be expensive.
