CHA 101: A Beginners Guide to Community Health Assessments
If everyone around you is sprinting on your department’s CHA and you're afraid to ask the big questions, this guide is for you!
If you're new to public health, community benefit, or just your role, CHA is one of the first acronyms you'll run into. It's also one of the most important. A Community Health Assessment (CHA) is the foundation that most local health department and hospital community benefit work gets built on. Grants, accreditation, board reporting, cross-sector partnerships, and so much more all frequently trace back to this one process.
To get you up to speed, here's what the CHA actually is, how it differs from a few terms that get used interchangeably, and what the process really looks like from the inside. We hope it helps!
What Is a Community Health Assessment?
A CHA is the systematic process of collecting, analyzing, and reporting information about the health of your community, then using it to identify the community's most pressing needs. They typically look at chronic disease rates, access to care, behavioral health, housing, food security, and other social determinants of health.
Most CHAs combine two kinds of information:
Quantitative data — statistics pulled from sources like the CDC, county health rankings, hospital discharge records, and the census
Qualitative data — input gathered directly from the community through surveys, focus groups, or key informant interviews
Every dataset represents real lives, real communities, and real opportunities to drive meaningful change.
The numbers show you what's happening while the community input helps explain what matters most to the real people involved. Skip either half, and you’ll end up with a partial picture.
Why This Matters
A CHA isn't paperwork for its own sake. It's usually the thing driving:
Accreditation — a current CHA is a requirement for national Public Health Accreditation Board (PHAB) accreditation
Funding — grant applications and budget requests almost always need to point back to documented community needs
Hospital compliance — nonprofit hospitals will need an assessment on file to maintain tax-exempt status under IRS 501(r)
Partnership alignment — a shared assessment gives hospitals, health departments, and community organizations a common set of priorities to organize efforts around
In other words, a lot of the work that follows (where staff time goes, where grant dollars get targeted, which board conversations happen) traces back to this one document.
So Here’s The Basic CHA Process, Step by Step
Assemble a planning team. Bring in health department staff, hospital partners, and community organizations early. CHAs done in isolation tend to miss context that partners already have sitting in a filing cabinet somewhere.
Collect quantitative data. Pull data on demographics, chronic disease, mental health, maternal health, access to care, social determinants of health, and more from public and local sources.
Gather community input. Run surveys, focus groups, and key informant interviews to hear directly from residents, especially those in underserved populations who don't always show up in administrative data.
Identify priority health needs. Combine the data and the community input to land on a manageable list of priorities. Most CHAs settle somewhere between three and eight.
Write and publish the assessment. Turn the findings into a report (something more accessible than a PDF, like a public-facing health atlas or dashboard). Hint: Metopio can automate the first draft of your assessment and help you disseminate findings to your community.
Next, you’ll build your CHIP by developing an action plan with specific strategies, owners, and measures of success for each priority need identified in the CHA.
Where Sub-County Data Fits Into the Process
One mistake worth flagging early: county-level data alone can hide the exact disparities a CHA is designed to surface. A county's average life expectancy can look perfectly fine while masking a 20-year gap between neighborhoods just a few miles apart. If your assessment stops at the county line, you risk missing the populations who need attention most.
Building in census tract or ZIP code-level analysis from the start (not as an afterthought) is what turns a broad priority like "housing" or "access to care" into something specific enough to act on.
Common First-Timer Mistakes
Treating the CHA as a one-department project. The strongest CHAs pull in hospital, government, and community partners from day one, not just at the end for sign-off.
Collecting data without a plan for what to do with it. It's easy to end up with a pile of statistics and no clear priorities. Decide early on what questions the data actually needs to answer.
Publishing a static report and moving on. A CHA that only exists as a PDF from two years ago isn't useful to anyone trying to make a decision today.
Here We Go... Hands In!
A CHA can feel intimidating from the outside, but underneath the acronyms, it’s meant to be a structured, helpful way of answering the question every health department and hospital needs to answer anyway: what does our community need?
But if it all sounds like a lot to manage, you're not wrong — the good news is that you don't have to do it alone! We know that, between funding pressures, shrinking headcounts, and mounting community obligations, public health teams are being asked to do more faster than ever. That's why Metopio was built to handle the entire community health improvement cycle in one visible platform:
Collect data from national, state, and local sources instantly (plus your own surveys and qualitative inputs)
Organize everything in one place with your full team
Analyze trends and flag disparities with AI-powered tools that don't require an engineering degree
Disseminate findings through interactive health atlases and exportable reports your board and community will actually use.
CHA, CHIP, Atlas, Surveys, Program Management — one platform, every step of the workflow. If you want to see how we’re helping hundreds of teams nationwide move through the process faster, request a demo and we'll walk you through it.
