This chapter details apportionment during the 1830s and 1840s and the break with previously established precedent. During the 1830s, the argument for adequate representation was framed in geographic concerns, as population shifted away from many of the northeastern states. It became apparent that Jefferson’s divisor method affected small states more so than larger states, as these small states typically had larger fractions. Without representing fractions, many of these smaller states lost seats. During the 1830 apportionment, an alternative method was proposed by Daniel Webster that ultimately replaced Jefferson’s method in 1840. In addition to adopting a new method of apportionment, the 1842 Apportionment Act deviated from the previously established precedent of continually increasing the size of the House to meet representational demands. This is the only time in history that Congress chose to reduce the number of seats. To compensate for the loss in seats, the Apportionment Act likewise required states adopt single-member districts.
