One country.
Different price levels.
Explore how prices vary across states in 2D or 3D. Raise the depth, amplify the differences, and follow price levels over time.
An index of 110 means prices are 10% above the national average for that year.

Amplified relief makes state differences easier to see.
The same color represents the same index value in every year.
Read changes relative to the country.
The national average equals 100 in each year. A rising RPP means a state's prices increased relative to the U.S. average. RPP changes alone do not measure inflation. “Within year” stretches the colors to that year's lowest and highest values; use “Across years” for consistent comparisons.
How the 3D heights work
Height is a visual comparison, not a zero-based RPP axis or physical terrain. For each measure and geographic scope, the baseline is the lowest RPP across 2008–2024, rounded down to 0.1. Height = depth × [8 + 75 × difference boost × (RPP − baseline) / (historical maximum − baseline)]. The baseline and height scale stay fixed when the year changes. Increasing depth scales the relief; increasing difference boost multiplies every pairwise height difference equally. Colors, rankings, tooltips and downloads use the original RPP values. The color-scale selector affects color only. Use Reset view to fit tall states, or 2D flat for an unobstructed comparison.
