2011 Redistricting: What it Means to Municipalities Chris Nida Research Analyst, N.C. League of Municipalities NCLM Annual Conference October 24, 2011
Agenda • What the Census Showed • Redistricting Basics • Implications of Redistricting for Municipalities
Redistricting • Legally required after completion of decennial census • Maps drawn and approved by legislature; no gubernatorial veto • Must be approved by U.S. Justice Department or federal courts before going into effect
Population Shifts Leading to Greater Municipal Influence? • Mecklenburg and Wake counties added two House seats and one Senate seat each • Greater representation in largest urban areas not necessarily signaling greater overall influence of cities and towns
Conclusions • Mixed bag for municipalities – some benefit, while some see influence potentially diluted • Working together crucial for many municipalities sharing districts • Subject to change pending final approval

Municipal Estimates: Methods, Data and Changes Jennifer Song, State Demographer, Office of State Budget and Management
September 2011 Data Release • July 1, 2010 Certified County Estimates • July 1, 2010 Certified Municipal Estimates • Final 2011-2031 State and County Projection Series
2011 Data Release Highlights • July 1, 2010 County and Municipal Estimates incorporate Census 2010 data as the new base. • CQR challenges accepted by the Census Bureau will be used as the base in subsequent estimates.
Guidelines on Data Usage DO NOT COMPARE: Last year’s 2009 municipal estimates with the current July 1, 2010 municipal estimates. DO COMPARE: • July 1, 2010 municipal estimates to Census 2010 and previous Census counts. • Smoothed county estimates from 2000-2009 which are consistent with both Census 2000 and Census 2010.
Why the difference? • 2009 estimates used 2000 Census as base; 2010 estimates use 2010 Census as base • Input data – annexation data, housing unit counts • The ‘smoothing’ nature of estimates and changing patterns of growth
The Municipal Estimates Model • Will use Census 2010 as the base • Uses data on annexations, group quarters and housing submitted by the municipalities • Is a 3-method model
Method 1: Municipality Grows Like the County • Assumes the non-group quarters population of the municipality grows at the same rate as the county population • This was the only method used this year (for the July 1, 2010 estimates)
Method 2: Municipality Grows Like it Has in the Past • Grows the municipality based on past growth trends. • Assumes growth will be different in different parts of the municipality. Separate growth rates for: • The muncipal core (area incorporated prior to 2000) • The municipal suburban area (area incorporated between the 2000 and 2010 Census) • Newly annexed areas
Method 3: Population Grows Like Housing • Grows the municipality’s population at the same rate as it’s housing unit share • As the municipality’s share of the county’s housing stock changes, its share of the county’s population is changed at the same rate • Most similar to the Census Bureau’s estimates method
Putting it all together • Traditionally the 3 methods have been weighted equally (i.e., averaged) • After testing with Census 2010, we will be introducing 3 alternative weighting approaches: • Equal weights – i.e, all three methods predicted equally well for the muncipality • 50%, 25%, 25% - one method predicted particularly well for the municipality • 40%, 40%, 20% - two methods predicted about equally well
Our Annual Surveys – Boundary and Annexation Survey • Asks for annexation data, occupied housing units and land areas • This is our main source of data about annexations – if they aren’t reported, they don’t get counted. • Important to update occupied housing unit counts to get the most accurate estimate • Report all annexations – we also estimate land area, so even commercial annexations should be included
Our Annual Surveys – Group Quarters • Verify that group quarters facilities are correctly located • Inform us about new facilities or missing facilities • In a few cases (such as orphanages or monasteries) provides us population counts • Only track facilities with 20 or more long-term residents • Assisted living facilities and jails are not considered group quarters
Our Annual Surveys – Housing Unit Data • Effort to improve on Census Bureau housing estimates – will still serve as default • The main data that is used for Method 3 • Working with the Census Bureau to submit the data to them as well
Keep in Touch! • Even if you have no changes, return the surveys • If your contact information changes, let our office know • If you submit a CQR challenge, let us know • Our surveys are separate from those sent out by the Census Bureau
