Redistricting prior to 2011 State Statutes (1980 s) - Reflect a good faith effort to apportion the legislature giving due consideration to the maintenance of the integrity of political subdivisions and of communities of interest. [4. 001(3)] Assembly and Senate districts were determined by the courts and not the legislature in the 1990 s and 2000 s. Summer of 2011 Act 39 (August 8, 2011) Local Redistricting - Wards and Supervisory Districts Act 43 (August 23, 2011) Redistricting of Senate and Assembly Districts

Redistricting Act 39 Section 5. 15 (1) (a) 2. indicates that wards are to be created in such a way that aldermanic and supervisory districts can be created allowing enhanced participation by members of racial or language minority groups. Act 43 created the 2011 assembly and senate districts and repealed the language regarding communities of interest. 2001 Blocks 2011 Blocks Wards Legislative Districts Wards

Results

Findings • Percent minority population increased while percent non-Hispanic white population decreased from 2000 to 2010. • Persons of color appear to be more dispersed throughout the State of Wisconsin from 2000 to 2010. • Percent population (over 18) of majority minority population has increased for African American, Hispanic and native American populations within assembly districts. • Asian American percent population (over 18) remained the same within assembly districts.

Future Research • Evaluate population in assembly districts with a higher concentration of minority populations. • Compare 2000 & 2010 minority population by local wards. • Compare 2010 population by 2001 assembly districts to 2000 population by 2001 assembly districts.
