The map is a visual summary; every value is in the table below, which is the keyboard and screen-reader path. Groups are quintiles of the values shown (a derived grouping). Boundaries: Natural Earth (public domain), simplified. Alaska and Hawaii are shown as insets, not to scale.

Rank is derived by Quadranac: 1 = highest value; ties share a rank. The ranked value is itself derived; see the source table for the method. Values are as published in the source table.

Note: Travel and fuel are counted where they happen, so states with heavy through traffic score high per resident.
