Research & Polling, Inc.3 Redistricting What is “redistricting”? Draw (and re-draw) lines that determine which voters are represented by each district Why redistrict? Decennial Census Most current population data Population shifts within an area District growth slower than the area as a whole District might gain population District growth faster than the area as a whole District might lose population District matches city growth rate Might remain unchanged, depending on neighboring districts

Research & Polling, Inc.7 Principles of Districting Equal population Minority Voting Rights Compactness Contiguity Communities of interest
8
Research & Polling, Inc.8 Equal Population Based on most recent Decennial Census Includes everyone, including, but not limited to: Adults Children Citizens College students in dorms Prisoners Non-citizens Undocumented immigrants Foreign students Foreign workers (e.g. German Air Force personnel at Holloman AFB) Not limited to registered voters
9
Research & Polling, Inc.9 Constitutional Mandate to Redistrict Gray v. Sanders, 1963 “One person, one vote” Equal population = equal representation Congress: as equal as possible State legislature, other entities: 10% spread, if there’s a good reason
10
Research & Polling, Inc.10 Ideal Population Ideal population = total population / # of districts Using 2010 Census City of Las Cruces: 97,618 / 6 = 16,270 Change from 2000 to 2010 2000 Census2010 CensusChange% Change Las Cruces74,26797,61823,35131.4% 2000 Census Ideal Population 2010 Census Ideal PopulationChange% Change District Ideal12,37816,2703,89231.4%
11
Research & Polling, Inc.11 Substantially Equal Population Districts must be “substantially equal” No more than 10% total deviation Within +5% of the ideal population City of Las Cruces, 2010 Census Population of each district (ideal pop ±5%) 16,270 + 813 range: 15,457 – 17,083 Based on total population, not registered voters
12
Research & Polling, Inc.12 Minority Voting Strength Give the minority population an opportunity to elect a candidate of their choice Do not dilute voting strength of ethnic/language minority groups (Voting Rights Act, Section 2): Native Americans African Americans Hispanics Do not create districts in which race is the predominant criterion in subordination of traditional districting principles (Shaw v. Reno, 509 U.S. 630 (1993))
13
Research & Polling, Inc.13 Minority Voting Strength – cont. Three criteria that need to meet to require single- member districts under federal case law ( Thornburg v. Gingles, 478 U.S. 30 (1986)) Minority population is compact and large enough to constitute a majority in a single-member district Minority population is politically cohesive Bloc voting
14
Research & Polling, Inc.14 Minority Voting Strength Dilution Packing Cracking
15
Research & Polling, Inc.15 Dilute through Packing Concentrate as much of a minority group into as few districts as possible to minimize the number of districts in which the minority could elect a candidate of their choice Avoid packing Blue – minority areas
16
Research & Polling, Inc.16 Dilute Through Cracking Split up a minority into as many districts as possible to minimize influence in any given district Avoid cracking Blue – minority areas
17
Research & Polling, Inc.17 Neither Packed nor Cracked In the example, provides two minority districts whereby the minority group has a chance to elect a candidate of their choice Blue – minority areas
18
Research & Polling, Inc.18 Compactness Different ways to measure compactness None are perfect Refers to shape, not geographic size Could have a very large district in area that is compact in shape A jurisdiction’s irregular outer boundary can affect the compactness measures of a district
19
Research & Polling, Inc.19 Compactness Compact: Not Compact: NC – 12 th CD 1991 TX – 18 th CD 1991 NM – 3 rd CD 1991
20
Research & Polling, Inc.20 Contiguity No islands of territory One distinct part, not two or more Contiguous: Not Contiguous: A B C A B C A A
21
Research & Polling, Inc.21 Communities of Interest All other factors which determine where a district boundary could be drawn Maintaining core of existing districts Protection of incumbents Respecting political subdivisions (e.g. avoid precinct splits) Also includes, but not limited to: Neighborhoods Cultural / historical traditions Geographic boundaries Growth patterns Can be considered as long as previous districting principles are not violated
