Tribal Data Supporting Community Strengths

The Epidemiology and Surveillance Unit maintains and expands the Northwest Tribal Epidemiology Center’s (NWTEC) capacity to collect and share accurate, timely data on Tribal health priorities and issues affecting American Indians and Alaska Natives (AI/AN) in Idaho, Oregon, and Washington.

How we work for our Tribes

  • Develop community health profiles, topic-specific fact sheets and dashboards, presentations, and other data products
  • Provide epidemiology-related training and capacity building
  • Share subject-specific epidemiology knowledge (including in the areas of substance use, chronic disease, cancer, and other conditions)

About Data Requests

Types of assistance that we can provide:

  • Data analysis and interpretation
  • Survey development
  • Health data literacy trainings
  • Community health assessment and improvement planning

For most requests, we estimate Tribal regions and Tribal data using data for the counties in the Tribe’s Indian Health Services (IHS) Purchased/Referred Care Delivery Area (PRCDA). The PRCDA region is generally the best approximation available, because we do not have access to Tribal-specific data or Tribal enrollment data (unless provided to us by the Tribe).

NOTE: we only provide data and technical assistance to Tribes and Tribal partners. If you are not affiliated with a Tribe or Tribal organization, please reach out to your state’s health department for data assistance.

Requests that involve data analysis and interpretation can take 1-3 months to complete, depending on the volume of requests. We appreciate your patience.

Helpful Links

For requests that involve data analysis and interpretation, the datasets below are available. The years available vary for the 3 states of Idaho, Oregon, and Washington State. If you are looking for data that is not listed below (https://www.npaihb.org/wp-content/uploads/2026/05/NWTEC-Data-Catalog.pdf), please fill out the DRTA form above and we can set up a meeting to discuss it.
