The 10 smallest US states

Small area does not mean few residents

A state can have a small geographic footprint and a relatively large population. Population density combines those two measurements, while this question uses area alone. Rhode Island and New Jersey illustrate why the most densely settled states can also be geographically small. A population ranking would put different states at the bottom, so an answer that is familiar from a least-populous-states list should not be assumed to qualify here. The number of residents is simply outside this metric.

Hawaii shows why water coverage matters

The water assigned to a state is included in its total. Hawaii’s islands and surrounding Census-defined water areas make the land-only comparison especially different from the total-area one. Treating an archipelago’s dry land as its entire area would use a different column. The same issue affects coastal and inland-water states in less obvious ways. A consistent table is preferable to assembling values from references that use different coastline or water-boundary conventions.

Read the units and direction together

The Census reference reports multiple area columns and units, so the column heading belongs alongside any reproduced figure. A consistent conversion from square miles to square kilometres cannot reverse an order, but mixing the units across rows can. The words smallest first are also essential: rank one means the minimum, rather than the maximum. Washington, DC may be smaller than many states, but it does not enter a fifty-state list. The archive keeps the 2010 measurement edition so later geographic revisions do not alter replay answers. Before comparing another reference, confirm that it includes water, excludes territories and DC, and sorts in the same ascending direction.
