Every county, on one line
Each dot is one county, placed by its latest CDC PLACES estimate. Choose a measure and the state rearranges; the table lists the ten highest and lowest with their 95% confidence intervals.

Reading the numbers
- Confidence intervals
- The range after a value (for example, 95% CI 8.1 – 9.9) shows the uncertainty in the estimate, as published by its source. Wider ranges mean less certainty. Poverty uses the Census Bureau’s 90% margin of error instead. Overlapping or non-overlapping ranges alone do not establish whether a difference between counties is meaningful.
- Percentage points
- The gap between two percentages is measured in percentage points. A change from 9% to 12% is 3 percentage points, which is a 33% relative increase. Vellora labels which of the two it shows.
- Modelled estimates
- CDC PLACES values are model-based small-area estimates: CDC combines national BRFSS survey responses with county population data in a statistical model rather than counting every resident. They describe likely county levels, and CDC states the model does not support tracking change over time.

Our mission
Vellora exists to make health in every one of Texas’s 254 counties easier to understand — so that where someone lives is never a reason they can’t learn about the conditions that shape their community.
We pair plain-language health education with honest, carefully sourced county data, so students, families, educators and researchers can ask better questions about health across Texas — and see clearly what the evidence can and cannot tell them.

Plain-language articles written from cited CDC, NIH and MedlinePlus sources, with every fact linked to its reference.
- Understanding Cardiovascular Disease
An introduction to the major types of heart and blood-vessel disease and how they are measured in population health.
