Visual form
Year-tabbed US county choropleth map.
Layout / body structure
The chart is a county-level map of the United States with year tabs for 2018 and 2022. A legend beneath the map explains the insurer-count color scale and no-data areas.
What is being compared
It compares exchange participation by county, measured as the number of participating health insurers in each county, across 2018 and 2022.
Measurement system
The color scale encodes the count of participating insurers: 1, 2, 3 or 4, at least 5, plus a gray no-data category.
Visible structure inside the graphic
The visible 2018 tab uses light-to-dark blues across counties, with many light counties in the central and eastern United States and darker clusters in parts of the West, Northeast, and selected metro regions.
Main takeaway from the visual
The map shows that county-level insurer choice expanded over the period, with the darker multi-insurer categories becoming more widespread by the later view.
Key standout values or extremes
The legend makes the main extreme explicit: counties with at least five participating insurers are the darkest category, while one-insurer counties are the lightest blue category.
Controls / sequence, when applicable
The year tabs switch the same county map between 2018 and 2022 inside the chart.
Companion media, when applicable
The chart is the full visual on this page. There is no separate companion audio or video outside the visual.
