Does 24 not sound like a lot? Very few bills are ever enacted — most legislators sponsor only a handful that are signed into law. But there are other legislative activities that we don’t track that are also important, including offering amendments, committee work and oversight of the other branches, and constituent services.

We consider a bill enacted if one of the following is true: a) it is enacted itself, b) it has a companion bill in the other chamber (as identified by Congress) which was enacted, or c) if at least about half of its provisions were incorporated into bills that were enacted (as determined by an automated text analysis, applicable beginning with bills in the 110th Congress).
