An OCTA Research survey conducted in December 2023 found that more than half of Filipinos are in favor of the government working with the International Criminal Court (ICC) to investigate drug-related killings that occurred under the Duterte administration.

The survey results released on Sunday, Feb. 18 showed that 55 percent of adult Filipinos agree that the Philippine government should cooperate with the ICC's investigation into drug-related deaths, while 45 percent disagree.

Across major areas, OCTA said the percentage of adult Filipinos who support the government’s collaboration with the ICC ranged from 42 to 65 percent: 65 percent in Balance Luzon, 52 percent in Metro Manila, 50 percent in Visayas, and 42 percent in Mindanao.

In contrast, Mindanao has the highest percentage of adult Filipinos who "do not favor" the government cooperating with the ICC in its investigation (58 percent), while Balance Luzon has the lowest (35 percent).

OCTA also said that the proportion of adult Filipinos who agree with the Philippines working with the ICC varied between 55 and 57 percent, based on socioeconomic classes.

It pointed out that there were no major differences among socioeconomic classes, with most adult Filipinos agreeing to the government cooperating with the ICC in its investigation.

In terms of age groups, OCTA said adult Filipinos who support the Philippine government-ICC cooperation ranged from 50 to 67 percent.

Those who are 75 years of age and older had the highest support (67 percent), while those who are 35 to 44 years old had the lowest support (50 percent), it pointed out.

Meanwhile, Filipinos who are 35 to 44 years old are the most likely to oppose cooperation with the ICC investigation (50 percent), while those who are 75 years old or older (33 percent) are the least likely to do so.

Moreover, OCTA observed that adult Filipinos living in rural areas (57 percent) expressed marginally greater support than adult Filipinos living in urban areas (54 percent) for the government's cooperation with the ICC in its inquiry.

The proportion of adult Filipinos who support this idea varied depending on gender—56 percent of males and 55 percent of females expressed their agreement.

In terms of educational attainment, OCTA said support for the government's cooperation with ICC varied from 53 to 62 percent.

Adult Filipinos with college or postgraduate education showed the highest percentage of support (62 percent), while those with high school education showed the lowest percentage (53 percent).

The Fourth Quarter 2023 Tugon ng Masa survey was fielded from Dec. 10 to 14 through face-to-face interviews of 1,200 adult respondents nationwide.

It has a ±3 percent margin of error at a 95 percent confidence level, with subnational estimates for Metro Manila, Balance Luzon, Visayas, and Mindanao at a ±6 percent margin of error.
