This document summarizes a study about the migration of Ilonggos people from Western Visayas to Tacurong, Cotabato (now Sultan Kudarat province) between 1930-1960s. It provides background on the massive migration of Ilonggos to Mindanao during this time period due to overpopulation and lack of opportunity in Iloilo province. The study aims to map this migration based on oral histories, including the routes taken, how it changed the landscape of Tacurong, and their settlement and adaptation in the new area. It outlines the methodology used, which includes interviews and archival research, and reviews related literature on internal migration in the Philippines.
