Coverage by jurisdiction
How many bills CapitolMath holds for each state and Congress, which sessions, how recent, and whose calendar it carries.
Every state legislature and the U.S. Congress publishes its record differently, so what CapitolMath holds varies from one jurisdiction to the next. This table is read from the data itself, every few hours, so it shows what's actually there today.
By jurisdiction#
This table couldn't be loaded just now.
- Bills — every bill and resolution held for the jurisdiction, across all its sessions.
- Sessions — the first and last session years held.
- Latest action — the most recent action recorded on any of its bills: the date the bill list's Last updated filter reads. A dash means the jurisdiction's bills don't carry that date yet, so that filter can't select them — use Session instead. An older date usually means the legislature isn't sitting.
- Calendar meetings — hearings, markups and floor sessions on the calendar. A dash means its calendar isn't carried yet.
How current it is#
The status page shows, for every jurisdiction, when its bills were last refreshed from the legislature and how often that happens. The front page's coverage table shows the same date as Last updated. A jurisdiction on the automatic schedule is refreshed daily while its legislature is in session and weekly when it isn't. Each one has one of four statuses:
- Up to date — refreshed within its target: 36 hours in session, 8 days out of it.
- Delayed — the last refresh is older than that, or the latest one failed and is being retried.
- Being checked — the latest refresh looked incomplete, or the data failed one of the consistency checks run after every refresh, and it's being looked into.
- Updated periodically — not on the automatic schedule yet; refreshed by hand.
The consistency checks compare a refresh with the legislature's own rhythm. Has a sitting legislature recorded any action lately, and does its calendar hold meetings at a time of year when it usually does? Do passed bills have their text? Do the seated members, plus recorded vacancies, fill each chamber? Has a session past its scheduled end been given an adjournment date? The two about activity are measured against the same point in the legislative cycle two years earlier, so a recess or an interim doesn't count as a problem; the others allow for a few ordinary gaps, like a seat left vacant.
Widgets show the same date in their footer, beside how often the data is refreshed.
What isn't everywhere#
Some parts of the record exist only where a legislature publishes them:
- Committee roll calls. Not every chamber publishes how each member voted in committee. In the U.S. Senate, committees largely report by voice vote, so for much of the chamber there is no per-member record at all. Alabama's and Arkansas's committees report by voice in both chambers, and Georgia's report without publishing a roll call, so their member votes are floor votes only. In Alaska, a committee's record is each member's recommendation on its report: do pass counts as yes, do not pass as no, and no recommendation or amend as neither. Delaware's committee reports count how many members signed favorable, on its merits or unfavorable, without naming them, so Delaware's member votes are floor votes only. Connecticut's committees are joint: representatives and senators sit and vote together, and each member's committee vote is recorded in their own chamber.
- Idaho's committees and substitutes. Idaho's committees vote by voice unless a member asks for a roll call, so Idaho's committee votes are the roll calls its committee minutes record. When a legislator is away, an acting substitute can sit and vote in their place; those votes count toward each roll call's total but aren't credited to the member, who didn't cast them.
- Illinois's 2023–24 committee votes. For the 103rd General Assembly (2023–24), Illinois no longer publishes each bill's vote history, so its floor votes come from the Assembly's own roll-call record and its committee votes from the roll-call documents that survive, about two in five of them. A committee vote with no surviving document keeps its outcome and tally without each member's vote. Committee meetings for those two years are the days each committee acted on a bill, since the hearing notices are no longer published. The 2025–26 Assembly has every vote and every hearing.
- Indiana's committee votes by consent. An Indiana committee takes some motions by consent rather than by roll call (an amendment, or the report itself). Those votes keep their outcome without each member's vote; every committee vote taken by roll call is there member by member, from the committee's own vote sheet.
- Iowa's 2023–24 House committees. In the 90th General Assembly (2023–24), the Iowa House journal printed each committee's recommendation without its vote, so Iowa's House committee votes begin in 2025; its Senate committee votes are there for both Assemblies, each member's vote from the committee's report.
- Kansas's committees and some floor votes. Kansas's committees report without a roll call, and the Committee of the Whole decides by voice, so Kansas's member votes are the chamber's recorded floor votes. A few recorded votes have no roll call published: the consent calendar, a resolution's final action and a line-item veto's override among them. Those keep their outcome and tally without each member's vote.
- Kentucky's committee votes. Kentucky publishes its committee votes only as scanned report forms, so Kentucky's member votes are the chamber's recorded floor votes, every roll call member by member. A committee's report still shows on each measure's history.
- Floor votes named by exception. Hawaii's floor records name only the members voting aye with reservations, no, or excused; every other member present voted aye. Those ayes are filled in from who held each seat that day, taken from the House and Senate journals, with resignations and appointments dated. Where a record gives too little to tell (a Senate resolution's adoption that names only its noes), the vote is shown without members.
- Vetoes. Only a handful of states write a veto into the bill's record, so the Vetoed outcome under-reports elsewhere.
- Calendars. Hearings and agendas are carried for the jurisdictions listed with meetings above; elsewhere the calendar shows session dates at most.
Where a gap matters, the app says so — a scorecard checks a session's roll calls before scoring it, and a webhook can tell you when a jurisdiction's updates start, stop or fail. See Data sources for where it comes from.
