Bills and workload in the Utah Legislature, 2007-2023

The materials below summarize the number of bills (including resolutions) considered by the Utah legislature in recent years. Some clarifications:

• The "day" starts at 1 on the first day of the session and counts up to 46, the last day of the session. (The Legislature does not count President's Day in calculating the 45-day session, but I do.)
• A bill's "age" is the number of days that have passed since the bill was first introduced. (Age is 1, not 0, on introduction day.)
• "Passed" means a bill passed the legislature (it was "enrolled"). I do not record here whether the governor signed or vetoed it.
• "Trend" plots are scaled so that the minimum and maximum values define the range of the vertical axis, which may have the incidental effect of causing some visual exaggeration. Consume wisely.

Key observations:

• Few bills are ready on day 1. Bill introductions got noticeably later beginning in 2009, when the Legislature's start date moved to the 4th Monday in January.
• Many bills never come to a vote. Some get held up in Rules and never get sent to a committee. Some die in committee. Some pass committee but don't make it to the floor before the session ends.
• Very few bills are voted down on the floor. Committees and prioritization, not negative votes, determine which bills fail. If a bill makes it to a final floor vote, it will probably pass. The action is in the committees and floor calendar prioritization.
• Bills introduced later in a session are more likely to fail.
