About this data
Data Source
Legislative effectiveness data comes from Congress.gov, covering full legislative history from the 97th through 119th Congress. Bill status and progression data is accessed through the Congress.gov API.
Bill Stages
Each bill is tracked through four stages: introduced, passed committee, passed chamber, and enacted into law. A bill is assigned its highest achieved stage. For example, a bill that passed the House but not the Senate is recorded as “passed chamber.”
Enactment Rate
Enactment rate is calculated as the number of laws enacted divided by the total number of bills introduced by that member. The vast majority of bills never advance past introduction, so even a low enactment rate can indicate above-average legislative effectiveness compared to peers.
Excluded Members
Members who have not introduced any legislation in the 119th Congress are not shown in this tool. Introducing legislation is the baseline for measuring effectiveness in this context.
What This Does NOT Show
This tool does not capture amendments to other members’ bills, committee-level contributions, bipartisan co-sponsorship counts, or non-legislative work such as oversight hearings. A member with few bills enacted may still be highly effective through committee work, amendments, or other legislative strategies not measured here.
Update Frequency
Updated periodically from Congress.gov as legislation progresses through the current Congress. Data reflects bill status at the time of the last refresh.
