House seats by state, 1790 to 2020
After every census, the seats in the U.S. House of Representatives are shared out again among the states. This page holds the seats each state had after every census from 1790 to 2020.
Every figure is the U.S. Census Bureau's. Seats are held for the whole period; resident population and people per seat only from 1910, because the Bureau's tables for earlier years give seats alone. A state that did not yet have seats, and the District of Columbia, which has no voting seat, show no figure. Nothing here is estimated.
Every census, with the House size
The 1800 census
For the 1800 census the Census Bureau lists 142 seats in the House.
Seats apportioned and seats listed. The Bureau's Table B gives 141 seats apportioned at this census, by the act of Jan. 14, 1802. Table 3, which this page maps, lists 142, a difference of 1. Table B's footnote says its figure leaves out seats Congress gave to states admitted after the apportionment.
States listed for the first time. Ohio (1 seat, joined the Union in 1803). Where a state joined the Union after the census year, Table 3 lists it in this column anyway, with the seats it was given when it joined.
13 states gained seats and 0 lost seats against the 1790 census; 35 seats moved between states. The largest gain was New York (+7). 1 state is listed for the first time and not counted here.

A dashed grey tile means the table gives no seat: the state was not yet part of the Union, or it is the District of Columbia, which has no voting seat. Select a state to see its seats over time. Each state is one equal square, so a small state is as easy to see as a large one. Shading is in five steps; the value is also written on each tile and in the table.

"New" in the change column means the table gives the state no seat in the column before, so all of its seats are first seats. Seats are those the Census Bureau prints for the census year. The United States row adds the state seats and equals the total the table prints.
