Who are the New York City Council’s most prolific lawmakers?

There’s a reason that elected officials in the New York City Council are called lawmakers, but not all of them live up to the label.

In 2019, half a dozen council members had zero bills become law, while four lawmakers – Costa Constantinides, Daniel Dromm and Helen Rosenthal, along with City Council Speaker Corey Johnson – led the way with 11 new laws apiece.

The tally was made as part of City & State’s analysis for its Best & Worst New York City Lawmakers list that was published earlier this week. We ranked each council member based on the number of new laws for which they were the first prime sponsor, from most to least. We counted bill introductions but left out resolutions, which have little impact. We included any bills signed in 2019, regardless of when they were introduced.

While bill signings signal effectiveness, we also wanted to measure effort – so we conducted the same analysis for bills introduced by lawmakers in 2019, regardless of where those measures ended up. (The full methodology is here.)

Here’s how each council member stacked up against the competition.
