Reference & methodology

Understand the data behind Legislation Lemur

Legislation Lemur is designed to make congressional information easier to explore without hiding where the information came from, how often it changes, or when a number is calculated rather than reported directly by an official source.

You do not need the technical details to browse the site. For reporting, research, or closer analysis, the sections below explain how updates, data quality, derived metrics, summaries, and Bill Signals are handled.

Source-traceable

Official source links and provenance are preserved where the underlying record supports them.

Regularly updated

Scheduled updates run throughout the week, with page-level freshness preferred when available.

Quality-checked

Duplicates, missing identifiers, relationships, coverage, and stale data are checked separately from ingestion success.

Calculation-validated

Important derived metrics are independently recomputed from canonical source data before sign-off.

Sources & provenance

Data sources & attribution

Legislation Lemur combines information from official congressional sources and organizes it into consistent bill, member, vote, committee, and search experiences. Where possible, records retain source information that lets you trace what you are seeing back to the underlying official record.

Official, derived, or generated?
  • Official source data — information published by congressional sources.
  • Normalized data — official information organized into consistent labels, relationships, or application-friendly formats.
  • Derived data — counts, percentages, rollups, rankings, and signals calculated from source data.
  • AI-assisted summaries — generated explanatory text, identified separately from official summaries.
Read more about provenance

For research-oriented use, provenance matters as much as the displayed value. Useful questions include:

  • Can the record be traced to a stable source identifier?
  • Is an official source link available where expected?
  • Is a summary official or generated?
  • Is a value current, historical, normalized, or derived?
  • Is missing information absent from the source, or did it fail to reach the application?

Freshness

How often is data updated?

Legislation Lemur follows a regular production update schedule. Times below are in Mountain Time. Updates are not instantaneous: an official source may publish new information before the next scheduled update, and larger runs can take time to complete.

Data areaNormal update schedule
Core bills, votes, and official-summary dataSunday–Thursday beginning around 6:00 p.m., plus Saturday beginning around 4:00 a.m.
Members and committeesWednesday around 2:00 a.m. and Saturday around 12:30 a.m.
Additional bill-summary processingSaturday around 11:00 a.m.

A page-level “last updated” or “last verified” timestamp is a better guide to the specific data you are viewing than the schedule alone. Scheduled start times do not mean every affected page changes at that exact minute.

Integrity

How we check data quality

A successful import is not enough by itself. Legislation Lemur also checks whether the resulting data makes sense and whether it reached the application correctly.

Identity & duplicates

We check whether records appear at their expected level and flag unexpected duplicates that could inflate counts or results.

Required information

Important identifiers and required fields are checked for completeness without treating legitimate optional-source omissions as errors.

Relationships

Connected bill, member, vote, committee, subject, and search records are checked for broken or orphaned relationships.

Coverage

Source data is reconciled with application-facing views so eligible records do not silently disappear, duplicate, or miss search and display layers.

Freshness

We distinguish a source update from the downstream refreshes required to make that update visible in the application.

User-facing consistency

Important public behaviors such as summaries, status mappings, search coverage, scores, and chart-ready data are checked against documented rules.

What a quality check does not mean

Passing validation does not mean every official record contains every possible field. Legitimate omissions, delayed publication, reserved records, and source-specific differences can all exist. Legislation Lemur should not manufacture values simply to make a record look complete.

Read the deeper data-quality method

Important datasets have an expected grain: what one row represents. Checks cover duplicate keys, required identifiers, referential integrity, source-to-application coverage, freshness, and operational consistency.

A later successful update can demonstrate recovery, but it does not rewrite an earlier incomplete run as successful. “The import ran” and “the displayed data is healthy” are treated as separate questions.

Derived metrics

How calculations are verified

Some numbers on Legislation Lemur are calculated rather than copied directly from an official source. For important derived metrics, a query running successfully is not treated as proof that the number is correct. The published result is independently recomputed from canonical source data and compared with the application value.

Canonical source rowsIndependent expected calculation
Published application objectPublished value
How we validate calculations

A calculation contract should define:

  • metric name and business meaning;
  • published and source grain;
  • numerator and denominator where applicable;
  • filters and exclusions;
  • current-versus-historical scope;
  • null and zero behavior;
  • date or “as of” basis;
  • rounding and tolerance;
  • expected edge cases.

Counts generally require exact agreement. Percentages, ratios, and other decimals may use a documented tolerance when rounding or numerical behavior makes exact equality inappropriate. Missing rows, unexpected rows, and duplicate keys are also reconciliation failures even when individual values happen to match.

Discovery tools

Bill Signals

Bill Signals help surface legislation with a larger overall footprint or more recent activity. They are relative discovery indicators — not predictions, endorsements, ideological ratings, or measures of policy importance.

Overall legislative footprint

Impact Score

Impact Score summarizes how much observable legislative activity and attention a bill has accumulated in the data available to Legislation Lemur. A higher score means a larger observed footprint; it does not mean the bill is more important or more likely to become law.

High footprintModerate footprintLimited footprint

Recent legislative activity

Momentum

Momentum emphasizes how recently active or changing a bill appears in the available data. A higher score means comparatively fresh activity or updates; it does not necessarily mean the bill advanced toward enactment.

High recent activitySome recent activityLow recent activity
High Impact + low MomentumSubstantial earlier footprint; quieter recently.
Limited Impact + high MomentumSmaller overall record with fresh recent activity.
High Impact + high MomentumEstablished footprint with comparatively fresh activity.
Limited Impact + low MomentumSmaller observable footprint with little recent activity.
Read the Bill Signal methodology

Impact Score and Momentum are calculated bill attributes rather than official congressional ratings. Their formulas are part of the bill-metrics calculation contract and are independently checked against source data.

  • Current, not historical: when a signal appears beside historical member activity, it describes the bill’s current calculated state rather than its score when the relationship began.
  • Relative: scores can change as congressional data is added or updated.
  • Missing is not zero: when a signal cannot be calculated, the interface should show “Signal unavailable” rather than silently treating it as zero.

The exact current formula and weights are intentionally not reproduced here until they are published directly from the current validated metric specification.

Summaries

Official & AI-assisted summaries

Official source text and generated explanatory text are not treated as interchangeable. When an official bill summary is available, the canonical summary experience prefers the official source. AI-assisted summary text is identified separately and should not be mistaken for official congressional language.

Official summary

Summary text supplied by an official congressional source and presented as official source material.

AI-assisted summary

Generated explanatory text used when appropriate and identified separately from official congressional language.

Research use

For journalists & researchers

Legislation Lemur is designed to make source basis, current-versus-historical scope, freshness, missing-data behavior, and derived calculations understandable without requiring knowledge of the project’s internal infrastructure.

Research and interpretation notes
  • Use official source links when you need the authoritative legislative record or legal text.
  • Treat normalized and derived values as Legislation Lemur application data, not as official congressional ratings.
  • Check page-level freshness where available when timing matters.
  • Do not interpret missing optional information as zero unless the metric or field definition explicitly says so.
  • For time-sensitive or legal conclusions, verify the underlying official record directly.

Legislation Lemur uses validation to reduce the risk of silent structural, freshness, coverage, provenance, and calculation errors. Official congressional sources remain the final authority for precise legislative records and legal text.

Congressional reference

Reference library

Plain-language notes for common congressional terms you’ll see in bill listings, committee pages, and legislative timelines.

Bill basics

Bill prefixes

The prefix tells you what kind of legislative item it is and which chamber introduced it.

PrefixMeaningNotes
H.R.House billA bill introduced in the House of Representatives.
S.Senate billA bill introduced in the Senate.
H.Res.House simple resolutionAffects House rules or expresses House sentiment; does not go to the President.
S.Res.Senate simple resolutionAffects Senate rules or expresses Senate sentiment; does not go to the President.
H.Con.Res.House concurrent resolutionInvolves both chambers; generally does not go to the President.
S.Con.Res.Senate concurrent resolutionInvolves both chambers; generally does not go to the President.
H.J.Res.House joint resolutionIf passed by both chambers, typically goes to the President, or can propose constitutional amendments.
S.J.Res.Senate joint resolutionSame idea as H.J.Res., introduced in the Senate.
Committees

Committee types

Committees are usually grouped into a few core categories. These labels explain how a committee is formed and the type of work it handles.

Standing

Permanent committees with legislative jurisdiction, hearings, oversight responsibilities, and bill development work.

Select / Special

Often created to investigate, study, or focus on issues that cross jurisdictions or do not fit neatly into a standing committee.

Joint

Committees made up of Members from both chambers, often focused on studies or administrative and oversight work.

Conference

Temporary committees usually formed to reconcile House and Senate versions of a measure.

Congress basics

Congress numbers and sessions

A Congress number groups time in the federal legislature. Each new Congress begins after a federal election cycle.

Congress number

Example: H.R. 1234 (119th) means the bill was introduced during the 119th Congress.

How long it lasts

A Congress lasts two years and is typically divided into two annual sessions. Bills usually do not carry over after a Congress ends.

Procedure terms

Common bill timeline terms

These are terms you’ll often see in actions, committee updates, and status timelines.

Reported

A committee has finished considering a bill and sent it back to the full chamber with a recommendation.

Markup

A committee session where members debate, amend, and revise legislation before deciding whether to advance it.

Cloture

The Senate process used to end debate and move toward a vote. Bills can stall if cloture cannot be invoked.

Laid on the table

A parliamentary action that sets aside a measure or motion without further debate.

Measures

Resolutions and bill versions

Different measure types have different paths and legal effects.

Simple resolution

Applies to one chamber and does not go to the President. Usually styled H.Res. or S.Res.

Concurrent resolution

Involves both chambers and generally does not go to the President.

Joint resolution

Functions more like a bill and typically goes to the President, or proposes constitutional amendments.

Engrossed vs. enrolled

Engrossed includes amendments passed by one chamber. Enrolled is the final version passed by both chambers and sent to the President.

Final actions

Vetoes and reconciliation

Some process terms matter most near the end of a bill’s path or during budget-related packages.

Pocket veto

Occurs when the President does not sign a bill and Congress adjourns before the bill can automatically become law.

Reconciliation

A special budget-related process often used for major tax and spending legislation with clear budget impacts.
