Defining “Communities of Interest”
Under California Elections Code, “community of interest” has a very specific definition in the context of redistricting:
Definitions of “communities of interest” do not include relationships with political parties, incumbents, or political candidates.
A “community of interest” is a population that
shares common social or economic interests that
should be included within a single district for
purposes of its effective and fair representation.

*Ideal District Size: Each district must contain about 13,326 people 8 Population Balance Math
Ideal district size = 13,326
Calculated by dividing City’s the total population by the number of districts
66,184/5 = 13,326.8
Total deviation = 647
Calculated by subtracting the smallest district’s population from the largest district’s population
D5 (13,580) - D3 (12,933) = 647
Total deviation % = 4.89%
Calculated by the subtracting the smallest deviation from the largest deviation
(2.59%) - (-2.3%) = 4.89%
