The Ilonggo community, originating from the Panay Island region, also represents a significant settler group in Lake Sebu. These migrant populations have integrated into the local social fabric, contributing to the economic and cultural dynamics of the municipality. The interplay between the long-standing indigenous groups and these settler communities shapes the contemporary social structure of Lake Sebu.

The 2024 census recorded a total population of 84,252 people for the municipality, reflecting the cumulative growth of these diverse ethnic groups (Philippine Statistics Authority). This demographic makeup underscores Lake Sebu's role as a multi-ethnic hub in South Cotabato, where indigenous heritage and migrant settlement patterns coexist. The presence of the T'boli, Tiruray, Ubos, Manobo, Maguindanao, and Ilonggo communities highlights the region's complex social history and ongoing cultural interactions.

Economy and Infrastructure

The economy of the Municipality of Lake Sebu is anchored in three primary sectors: aquaculture, agriculture, and ecotourism. These industries form the backbone of local livelihoods, leveraging the municipality’s natural resources and geographical advantages within the province of South Cotabato. The integration of these sectors has created a diversified economic profile that supports the growing population, which reached 84,252 people according to the 2024 census.

Aquaculture and Tilapia Production

Aquaculture, particularly the farming of Tilapia, is a dominant economic driver in Lake Sebu. The municipality is widely recognized for its high-quality Tilapia production, which benefits from the mineral-rich waters of the local lake.
