 APPENDIX A
PART IV
Apportionment Plan for the Maine Senate
The Maine Constitution indicates that the Maine Senate may be composed
of an odd number of districts between 31 and 35. The Commission
recommends no change in the present 35 number of Senate districts. The
Commission plan for the 35 districts divides only 4 municipalities. (Technical
corrections have been made to pp. 154, 156, 157, & 158.)
In apportioning Maine's 35 Senate Districts the Commission utilized the
2020 U.S. Census population figure of 1,362,359 for the State of Maine. The
median or ideal district was determined to have a population of 38,925. A
district population 5% above the median would be 40,871; a district 5% below
the median would be 36,979. The districts recommended by the Commission
range in population size from a low of 37,121 to a high of 40,798. The largest
deviation above the median for the Senate plan is 4.81%, and the largest
deviation below the median is – 4.63%.
The following chart depicts the population and deviation from the
median population for each of the 35 Senate Districts.
