CHNA data & reporting
Timely, geographically detailed condition estimates for community health needs assessments — including populations standard survey data often misses.
Public health data infrastructure · Minneapolis, Minnesota
Data infrastructure and analysis for the questions public health partners actually have.
County health departments, state agencies, academic researchers, and community organizations come to us with messy, sensitive, or fragmented data — and need something they can report on, map, link across systems, or put in front of a board.
We build the pipelines, analyses, and visualizations to get there — whatever the data challenge requires.
What we help with
The kinds of data problems public health partners bring us
Health equity & disparities
Small-area mapping and stratified analysis to show where burden concentrates and for whom.
Cross-system data linkage
Connect clinical, administrative, and program data without moving identifiable records between organizations.
Dashboards & visualization
Interactive maps, charts, and exports designed for program staff and policymakers — not just analysts.
Grant technical assistance
Data plans, evaluation design, and infrastructure language for CDC, NIH, HRSA, and state RFPs.
Historical & structural determinants
Join historical policy boundaries — housing, zoning, investment — with present-day health outcomes.
How partnerships typically evolve
Infrastructure first — AI when the foundation is ready
Most counties and public health agencies do not start with AI. They start with linked data, governance, and reporting — then equity analysis, then assisted workflows built on top. We do not lead with AI because there is rarely a foundation to automate yet.

Case studies
Each project shows the problem a partner faced, how we approached it, and what they could use at the end.
Cross-system linkage
Linking health records across systems
- Problem:
- A consortium needed prevalence estimates without pooling patient-level data at a central site.
- Approach:
- Common clinical data standard, privacy-preserving linkage, and governed aggregate outputs.
- Result:
- A working pipeline demo you can walk through step by step.
Population estimation
Health burden among people experiencing homelessness
- Problem:
- Agencies know PIT counts but lack condition burden estimates standard surveillance does not provide.
- Approach:
- HUD denominators plus literature prevalence rates, service geography, and explicit confidence ranges.
- Result:
- Reusable county/CoC methodology with map and service-desert layer.
Health equity geography
Measuring redlining's present-day health impact
- Problem:
- Partners needed to show how 1930s housing policy still correlates with health today.
- Approach:
- Historical boundaries joined to census-tract health estimates and an interactive public map.
- Result:
- Tract-level comparison across diabetes, asthma, and mental distress in the Twin Cities metro.
Who we work with
Public health agencies
State and local departments building surveillance, CHNA reporting, or program evaluation data systems.

Multi-site collaborations that need shared standards, linkage, and governed outputs across partners.
Researchers & community orgs
Teams studying population health who need linked data, geospatial analysis, or public-facing tools.
Grant applicants
Organizations preparing proposals that need credible data infrastructure and evaluation components.
