In the previous election, 6 Pro-Administration and 2 Anti-Administration Representatives had been elected. One representative, George Partridge (P) of the 5th district resigned August 14, 1790. His seat was vacant at the time of the 1790 elections, so that there were 5 Pro-Administration and 2 Anti-Administration incumbents, all of whom ran for re-election.
Three candidates ran in districts with different numbers from the previous election. It is not clear from the source used whether there was redistricting or if the districts had simply been renumbered.
Massachusetts law at the time required a majority for election. This occurred on the first ballot in the 1st, 2nd, 3rd and 4th districts. In the remaining four districts additional elections were required. In the 5th and 7th districts, a majority was achieved on the 2nd ballot. In the 8th district, a majority was achieved on the 4th ballot, while in the 6th district, 9 ballots were required.
