The median water share among these 100 entries is 0.919 %. The first and last entries span 0.093 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.
