The majority of the inhabitants of the province are Visayan; some Negritos are found on the interior of Tablas and Carabao and Manguianes or May-as in Sibuyan mountains.
Although part of Southern Tagalog, there are three distinct languages spoken as a native language by Romblon's inhabitants; they are Romblomanon or Ini, Bantoanon or Asi, and Inunhan or Onhan, which are classified as Visayan. Tagalog is widely understood, and English language stands as the medium of communication in business and trade.
The people of the province are mostly Christians: 75% of the population are Roman Catholic, while 25% belong to other Christian denominations such as the Philippine Independent Church, Iglesia ni Cristo, Seventh-day Adventist Church, Baptist churches, and Church of the Foursquare Gospel in the Philippines.
