While Congress is notorious for moving slow on legislation, some states are hard to keep up with – passing more than half of the bills they introduce each session.
Colorado is arguably the most efficient state at passing legislation. Each session, the legislature introduces about 626 bills and enacts 397 of these, or 63 percent. A close second is North Dakota. The state, on average, passes 553 of the 889 bills it introduces. Idaho has a 62 percent enacted rate, passing about 348 of the 560 bills it introduces.
In terms of volume, New York, by far, introduces the most amount of bills with an average of 12,389 bills per session. However, the state only enacts about 10 percent of them. Illinois and Massachusetts follow with 6,002 and 3,973 bills respectively.
Some states have a large volume of introduced bills, but they aren't the least efficient in passing legislation. Procedural oddities can affect efficiency, as can the nature of a state's legislative cycle.
Connecticut is the least efficient at enacting legislation. On average, the state introduces 2,316 bills and passes about 38 of them – leaving the legislature with only 1.6 percent of its bills enacted. Minnesota and New Jersey also have low enacted percentages. Minnesota passes about 4 percent of its legislation – or 145 of the 3,453 bills it introduces. New Jersey passes 189 bills out of the 3,533 it introduces, leaving it with a 5.3 percent enacted rate.
There are a few factors affecting the amount of legislation states pass and the volume of bills each state has during a session. Session schedule, single-party control and committee deadlines all contribute to how efficient a state is at enacting legislation. However, almost all states enact a higher percentage of bills than Congress, which passed 4.4 percent of the legislation it introduced in 2015.
