About this program
The Department of Health and Human Services Indian Health Service (IHS) funds cooperative agreements and grants to Tribes, Tribal organizations, urban Indian organizations, and intertribal consortia to provide epidemiological support for American Indian and Alaska Native populations through Tribal Epidemiology Centers and related public health resilience initiatives under Assistance Listing 93.231, with the most recent grant award issued on October 1, 2025.
The program supports epidemiological capacity building across all 12 IHS Administrative Areas. Core activities funded include disease surveillance and monitoring, health status data collection, evaluating delivery systems, identifying health priorities based on epidemiological evidence, and providing technical assistance to Tribes and urban Indian organizations. The funded activities have expanded significantly beyond traditional epidemiology to encompass broader public health services aligned with the 10 Essential Public Health Services—including substance abuse prevention and treatment, suicide prevention and intervention, domestic violence prevention, maternal and child health, chronic disease management, environmental health, and workforce development. Recent awards reflect substantial investment in behavioral health infrastructure, care coordination systems, community health assessment, and culturally appropriate service delivery.
The portfolio comprises 172 awards totaling $509.6 million in federal dollars obligated (with $525.1 million combined federal and non-federal share) spanning from 1996 to 2025. Awards are predominantly Project Grants (80 percent of awards, 137 total), with smaller shares of Block Grants (19 percent, 32 awards) and Cooperative Agreements (2 percent, 3 awards). The IHS dominates funding across the program, accounting for all 172 awards. Award activity surged in 2022 (112 awards), followed by a normalized cadence of 23 awards in 2024 and 1 award through October 2025. Recent awards range from approximately $400 thousand to $7.57 million, with typical implementation periods of three to five years.
Representative recent awards include the Chickasaw Nation's Native Public Health Resilience project ($1.6 million, July 2024) to expand health education and workforce development; the Rosebud Sioux Tribe's project ($3.2 million, July 2024) to expand public health resources addressing communicable and chronic disease; and the Connecting with Our Youth Suicide Prevention program in Rapid City, South Dakota ($6 million, May 2022) to expand behavioral health services and early intervention for youth and families.
