The Dinagat Islands, located in the Caraga region of northeastern Mindanao, Philippines, presents a distinctive demographic profile shaped by its geography, cultural history, and development over time. The province is made up of the main Dinagat Island and various smaller islands, covering an area of approximately 817.47 square kilometers (315.63 square miles). Its position between the Philippine Sea and Surigao Strait has influenced the settlement patterns and the intermingling of cultures in the region.

As of the 2020 census, the population of Dinagat Islands stands at 128,117, which makes up a small portion of both the Caraga region and Mindanao’s overall population. The population density is about 157 people per square kilometer (406 per square mile), reflecting a relatively low-density settlement compared to more urbanized areas.

The primary language spoken in the province is Cebuano, spoken by most of the population. In some municipalities, such as Dinagat and Cagdianao, Surigaonon is commonly used due to the proximity to Surigao del Norte. There is also a presence of Waray-Waray speakers in certain areas, particularly in Loreto’s Panamaon and Hibuson Island.

Religiously, the people of Dinagat Islands are predominantly Roman Catholic, with Christianity being the primary faith in the province. There are also notable communities that follow other Christian denominations, particularly the Philippine Benevolent Missionaries Association (PBMA). Despite the differences in religious beliefs, the province is known for its peaceful religious coexistence.

The province’s population is a blend of ethnic groups, with the original inhabitants being the Lumad people. Over time, settlers from various Visayan islands, including Cebu and Bohol, have moved to the area, creating a diverse ethnic landscape that combines indigenous and Visayan cultural influences.

Economically, the province relies heavily on agriculture, fishing, and mining. It has abundant mineral resources such as chromite, gold, and nickel, which contribute significantly to the local economy. Agriculture and fishing remain critical sectors for livelihood, as the people of Dinagat Islands depend on the rich natural resources of the region.

The average household size in Dinagat Islands is about 4.79 members, based on the most recent census data. This indicates that family units are typically smaller compared to other regions, which might influence social structures and relationships within communities.

Over the years, the province has seen steady population growth, driven by both natural increases and migration from other regions. This growth has implications for local infrastructure, public services, and resource management, all of which will need to adapt to support the growing population.

Overall, Dinagat Islands is a province with a rich cultural blend, a thriving agricultural and mining economy, and a steadily growing population that reflects the dynamic interplay of historical, economic, and social factors.
