Every district, and who holds it
Each district is colored by the party of the member who represents it. Switch between the two chambers, zoom in where the districts are small, and tap a district for its member.
District lines: 2024 Census Bureau cartographic boundary files. When zoomed in, drag the map to move around.
Your legislators
Every sitting member of the California State Legislature. Search by name or district, sort any column, and open a member to get to know them: their service, their committees and who funds their campaigns.
Statewide offices
The legislature
Loading the members…
"In office since" is the start of the member's unbroken service in the chamber they sit in now, from the Open States roster. For some of the longest-serving members the roster does not record when that service began; those say only what it does record, such as "before 2023".
The shape of every district
Every Senate and Assembly district in California, measured the same way from the Census Bureau's own boundary files. A score describes a shape. It does not say why the shape is what it is: rivers, county and city lines, the state's borders and the Voting Rights Act all shape districts. This page measures, and leaves the judging to you.
Analysis Every district, every measure
In district order, not ranked. Sort any column; hold Shift for a second one. Download the whole table to check it yourself, or compare California's congressional districts on the federal side.
Who lives in each district
Every Senate and Assembly district in California: how many people each holds and who they are, from the Census Bureau's 2020 count and its American Community Survey. The figures describe residents. They do not say why the lines run where they run, and a district's residents are not its voters.
Fact Every district, every figure
In district order, not ranked. Sort any column; hold Shift for a second one. A small \u00b1 is the Bureau's margin of error at 90 percent confidence. Download the whole table to check it yourself, or compare California's congressional districts on the federal side.
Where this comes from
Everything factual on these pages comes from public records, and each part says which. Nothing is edited by hand, and nobody is characterized: the pages show the record and leave the judging to you.
Members, service and committees
The Open States people project (public domain), which follows the California State Legislature's own member pages. Portraits are the official ones the chambers publish.
District lines
The U.S. Census Bureau's cartographic boundary files for the upper and lower chamber (2024 Census Bureau cartographic boundary files), drawn on the same map projection as the federal pages. "Use my location" is worked out against these lines on your own device.
Campaign money
the California Secretary of State's public downloads: gifts to candidates' committees, and independent spending for or against candidates. Organizations are named; people who gave, lobbyists included, are only ever counted in totals. Outside spending is always shown apart from donations, because the campaign never received it.
The shape of each district
Three published measures of compactness, computed from the same Census Bureau boundary files. The files and their fingerprints, the formulas, the checks and what a score cannot tell you are under Shapes, "Sources and methods".
Who lives in each district
The Census Bureau's 2020 count by district and its 2020-2024 American Community Survey estimates, with the Bureau's margins of error. The files and their fingerprints, the formulas for derived margins, the checks against the Bureau's own totals and what the figures cannot tell you are under People, "Sources and methods".
Life before the legislature
One paragraph, the opening of the member's Wikipedia article, fenced off and labelled wherever it appears. It is not an official record, anyone can edit it, and it is credited and linked every time (CC BY-SA 4.0).
Bills and recorded votes
Being added next, from LegiScan's weekly public datasets, which carry every bill and every roll call with each member's vote. When they arrive, each page will credit LegiScan as its terms ask.
