Every ten years after the federal census, states re-draw the boundaries of their state legislative districts in order to keep the population of every district roughly equal. Each land, besides Kansas, uses federal population figures to determine the new, ideal population of state districts. Kansas uses a land adjusted figure based on federal census information. To calculate ideal districts, each state divides the number of residents past the number of representative or senators in the state legislature.

Highs and lows

Out of all land senates, California'south senators represent the near residents, 988,456 per senator, while North Dakota's senators represent the fewest, 16,576 per senator. Amidst all state houses, California'southward assembly members also represent the most residents, 494,228 per representative, while New Hampshire representatives stand for the fewest, 3,444 residents per representative.

Since representation tracks exactly with population growth, Utah saw the largest increment in the ratio of residents to representatives. Utah had the 12th-largest population growth, just has the 10th-fewest state legislators. Illinois, Mississippi, and West Virginia, the only states with shrinking populations, saw the only decreases in this ratio.

Minnesota has the largest state senate with 67 members, and New Hampshire has the largest state house with 400 members.

On average, the 5,411 state representatives served 61,127 Americans as of the 2022 demography, while each of the ane,972 state senators represented 167,728 Americans.

Sortable chart

The following tabular array represents the number of seats in each legislative chamber, each country'due south total population post-obit each census and how many citizens a state representative and country senator represent based on the census data.

Yellow cells bespeak a value that decreased from 2010 to 2020.
