Despite what some New Hampshire legislators say publicly, drawing redistricting maps is NOT just a mathematical exercise.   Fair voting maps are nonpartisan and include communities of interest whenever and wherever possible, so that towns which have important connections like school districts get put together. 

Below is the criteria that the 250+ participants in the NH Map-a-Thon considered and approved.   These include required U.S. and NH Constitutional mandates,  court decisions, but also best practices as recommended by the Brennan Center and National Council of State Legislatures.

To see even more detail on the Map-a-Thon's criteria, visit our Redistricting Criteria work Google Sheet.   We encourage you to ask the NH House Special Committee on Redistricting and the NH Senate Redistricting Committee to disclose their criteria, which they have yet to do as of Oct. 23, 2021.

NH Constitution Part 2 [Art.] 9. ...every ten years thereafter, the legislature shall make an apportionment of representatives according to the last general census of the inhabitants of the state taken by authority of the United States or of this state. In making such apportionment, no town, ward or place shall be divided nor the boundaries thereof altered. Amended 1964 providing for equal representation. [Art.] 11. [Small Towns; Representation by Districts.] When the population of any town or ward, according to the last federal census, is within a reasonable deviation from the ideal population for one or more representative seats, the town or ward shall have its own district of one or more representative seats. The apportionment shall not deny any other town or ward membership in one non-floterial representative district. When any town, ward, or unincorporated place has fewer than the number of inhabitants necessary to entitle it to one representative, the legislature shall form those towns, wards, or unincorporated places into representative districts which contain a sufficient number of inhabitants to entitle each district so formed to one or more representatives for the entire district. In forming the districts, the boundaries of towns, wards, and unincorporated places shall be preserved and contiguous. The excess number of inhabitants of district may be added to the excess number of inhabitants of other districts to form at-large or floterial districts conforming to acceptable deviations. The legislature shall form the representative districts at the regular session following every decennial federal census. Amended November 7, 2006 to enable towns with sufficient population to have their own representative district and permits the use of floterial districts.

[Art.] 26. [Senatorial Districts, How Constituted.] And that the state may be equally represented in the senate, the legislature shall divide the state into single member districts, as nearly equal as may be in population, each consisting of contiguous towns, city wards and unincorporated places, without dividing any town, city ward or unincorporated place. The legislature shall form the single member districts at its next session after approval of this article by the voters of the state and thereafter at the regular session following each decennial federal census. Amended 1964 providing for election of senators on basis of population. [Art.] 26-a. [Division of Town, Ward or Place; Senatorial Districts.] Notwithstanding Article 26 or any other article, a law providing for an apportionment to form senatorial districts under Article 26 of Part Second may divide a town, ward or unincorporated place into two or more senatorial districts if such town, ward or place by referendum requests such division. November 22, 1978

[Art.] 65. [Executive Councilor Districts Provided for.] The legislature may, if the public good shall hereafter require it, divide the state into five districts, as nearly equal as may be, governing themselves by the number of population, each district to elect a councilor: And, in case of such division, the manner of the choice shall be conformable to the present mode of election in counties. Amended 1912

U.S. Constitution, Amendment XIV, section 2 Article One of the United States Constitution, elections to the House of Representatives are held every two years, and districts are apportioned amongst the states according to their respective numbers. Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives. ... Each congressional district is to be as equal in population to all other congressional districts in a state as practicable. The Constitution provides for proportional representation in the U.S. House of Representatives and the seats in the House are apportioned based on state population according to the constitutionally mandated Census.
