Delegate Positions on All Substantive Roll Calls at the United States Constitutional Convention, 1787

This data set contains 5,121 yay or nay positions (including preferences) on 620 substantive motions for 55 delegates who attended the United States Constitutional Convention held in 1787. Since delegate votes were not recorded at the Constitutional Convention -- only the votes of state delegations were recorded -- delegate votes were inferred from statements made by delegates during debate, motions and seconds, and the formal rule that the vote recorded for each state was determined by the majority of its delegation. This data set also contains state positions on each motion as well as category codes for each motion. Each observation includes the roll call number, the vote recorded for the state on the motion, and the vote or preference inferred for each delegate, including information about attendance.
