Read the differences behind ranks 1001–1100

The median water share among these 100 entries is 2.261 %. The first and last entries span 0.337 percentage points. This median describes the entries on this page, not the full national dataset. Pagination is a browsing boundary, not a distinct geographic region.

A percentage-point gap is the subtraction of two shares. It differs from a relative percentage change, and it does not tell you the difference in water square miles. Check each profile’s original water measurement if absolute water extent is your question.
