Bills in the Utah Legislature, 2007-2018

The table below summarizes the number of bills (including resolutions) heard 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 45, the last day of the session
  • A bill's "age" is the number of days that have passed since the bill was first introduced.
  • "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:

  • 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. That's what committees are for. They weed out bills that are unlikely to pass. If a bill makes it to the floor, it will probably pass. The action is in the committees.

Methodological note. References below to "last two weeks" of the session used to refer to its last 14 days. I changed my calculations (in March 2014) so that this refers to the last two calendar weeks (so a "week" always starts on Monday). Likewise for references to the "last week" or "last three weeks."
