Notes
Districts are filled by the party of the officials on this site who hold them; a hatched district has no one here today or is shared by members of more than one party. “Lines since” is the first general election held on the district’s lines: results before it describe a different place.
Who represents it
2 senators, 4 House members and a governor on this site, and 148 state legislators.
Each name links to the official’s profile: what they say, how they vote, their ideology and money.

About these figures
The figures from the American Community Survey are estimates from a sample, not a count. The ± beside each is its 90 percent margin of error: nine times in ten the true value lies within that range. In small districts the margins are wide, so a gap of a few points from United States may be noise. Shares are of everyone in the district, except education (adults 25 and over), poverty (people whose poverty status is known) and veterans (civilian adults).
These are the Census Bureau’s own estimates for the district; margins on shares are approximated from the counts’ margins.
The rural share counts the people living outside the urban areas the Census Bureau drew from the 2020 Census; it is a count, with no margin of error.
Opinion
What Iowa’s adults think, estimated from the lab’s national survey.
Estimates for each state come from multilevel regression and poststratification (MRP): a model of every respondent’s answers by age, race, education, sex and their state’s 2024 vote, weighted to the state’s population. Rank 1 is the highest of the 51 states. See Public Opinion for the questions and the national trends.

An estimate is uncertain, especially in small states: the 95% interval shows the range. Ranks between states whose intervals overlap mean little. Estimates as of Nov 3, 2026.
What its officials say
3.9% of Iowa’s officials’ statements make personal attacks, against 4.7% nationwide.
An AI model reads each statement (posts on X, press releases, newsletters, floor speeches) and marks the kinds of statement it contains; a rate is the share of statements with that label, in the officials’ current terms. The Iowa dashboard has the trends, topics and leaders.
| Kind of statement | All officials | Members of Congress | Legislators and governor | Nation |
|---|---|---|---|---|
| Personal attacks | 3.9% | 1.5% | 6.5% | 4.7% |
| Policy criticism | 13% | 18% | 8.0% | 16% |
| Policy discussion | 52% | 81% | 22% | 50% |
| Bipartisanship | 8.9% | 16% | 1.5% | 5.5% |

Ideology and lawmaking
15,359 bills in the Iowa legislature since 2019, 1,342 of them law (8.7%).
CSIP is the lab’s ideology score from roll calls, donations and text, on one scale for every official (0 is the centre of the scale, not “moderate” by definition). The legislature’s party gap is measured within each chamber from its own roll calls, in standard deviations of its members’ positions. See Bills for every legislature.

Threats and violence
8 federal prosecutions for threatening officials in Iowa, 21 threats or harassment of local officials since 2022, and 10 political violence events in the lab’s record.
Separate records, never added together: prosecutions the Justice Department announced (not every threat), the Bridging Divides Initiative’s record of threats and harassment against local officials, the lab’s record of political violence, the FBI’s hate crime statistics and the Crowd Counting Consortium’s protests. The Political Violence page has each record in full.

Notes
Reporting is voluntary: a year’s count rises and falls with the number of police agencies that took part, not only with crime. Few agencies reported in the early 1990s, and in 2021 the FBI took reports only through its incident-based system (NIBRS), which many agencies had not yet joined. The Political Violence page has each year’s coverage.
