There’s a reason they’re called lawmakers.

As we continue our breakdown of the best and worst New York City Council members, one of the most obvious factors in assessing each lawmaker’s performance is the number of bills they’ve had signed into law.

To measure this, we tallied bill introductions but left out resolutions, which have little real weight. Only a lawmaker who was the prime sponsor of a bill qualified in this analysis. To reward effort, one criterion was the number of bills introduced. And to reward effectiveness, the other legislative criterion was the number of bills signed into law. For these criteria, we used data from calendar year 2016.
