California’s Community-of-Interest Criterion

Applies only to geographic communitieso “The geographic integrity of any . . . community of interest shall

be respected . . . .”o “A community of interest is a contiguous population . . . .”

Defines communities in objective termso “A community of interest is a . . . population which shares

common social and economic interests . . . .”o “Examples of such shared interests are those common to an

urban area, a rural area, an industrial area, or an agricultural area, and those common to areas in which the people share similar living standards, use the same transportation facilities, [or] have similar work opportunities . . . .”

Excludes political considerationso “Communities of interest shall not include relationships with

political parties, incumbents, or political candidates.”
