“Everyone Counts” But Can Everyone Be Counted? Why the MAF/Tiger can make or break the 2010 Census for Indiana A presentation to the Indiana GIS Conference March 8, 2006 Carol O. Rogers State Census Liaison Director, Census BIDC for Indiana, Vice-Chair of the National State Data Center Steering Committee and Associate Director, Indiana Business Research Center Kelley School of Business Indiana University Indiana Data Center Program 27 years serving the nation with education and access to Census data.

Population Estimates for 2004: Indiana Barely Maintains Its Rank Indiana’s population reached 6.24 million on July 1, 2004, according to the Census Bureau’s recently released state population estimates. Our gain since 2003 was about 38,000, for a growth rate of 0.6 percent. The growth since Census 2000 was approximately 157,000, yielding a 2.6 percent increase for the period. The State of Washington Is Nipping at Our Heels The Midwest, including Indiana, Are Not Keeping Up in Population Growth

Well, We May Lose Congressional Influence Projected loss of seats in congress by 2030, by region

$300 Per Person in Federal Funding 10$3,000 20$6,000 30$9,000 40$12,000 50$15,000 60$18,000 70$21,000 80$24,000 90$27, $30,000 And we will certainly lose Federal Funding How much can $30,000 pay for in a town like Seymour or Linton?

How do we handle the new and account for the demolished?

Duplicate Addresses – the Bane of Matching!

What is this thing called MAF? The Address Control File (ACF) from the 1990 census was a starting point for the MAF. It has been updated with a variety of lists, including the delivery sequence file of the U.S.P.S. Millions of address records for physical location of housing units Includes location descriptions as well as nonresidential addresses Occupied or vacant “we” can’t see it because it is restricted by Title 13 of U.S.C. Answer: Master Address File

The Bureau will work with us In1994, Congress passed the Census Address List Improvement Act of 1994 (Public Law ) allowing the Bureau to improve its partnerships with local and tribal governments by allowing them to review and update the census address list before the decennial census.

Moving Forward The Census Bureau recognizes that: A modern census needs a modern MAF/TIGER Web-based system Global Positioning System (GPS) On-going LUCA Integrated MAF TIGER Will enhance LUCA (local update of census addresses) Will directly attack the issues of a complete and unduplicated address list Will facilitate automation and electronic collection

Are Special Only two states chosen to pilot test use of state level records to improve MAF Test performed in November and December May pave the way for “good information” states such as ours to improve the count and

Lessons Learned First, local information is always better Second, state records can help but should not replace LUCA Third, use our pilot test lessons to help local cities and towns prepare for LUCA

Okay, What Did We Do? Arc/GIS and Arc/Info as GIS platforms Parcel files for existing improvements (aka housing units) Building and Demolition Permits where available Five counties: Allen, Hendricks, Johnson, Lake, and Tippecanoe Local cooperation – fantastic!

Parcel records were generally good although varied a lot in terms of data format, quality and information attached. For example, parcel records not particularly useful in terms of multi-family units. This led to a fair amount of manual work. Rural routes and P.O. Boxes are problematic (no duh!) for geocoding as well as consistency between MAF and parcels Using TIGER is currently frustrating because of the street segment/address range issue (geocoded addresses cluster toward the ends of street segments). Indiana submitted close to 80,000 additional housing units to the Bureau for checking. Our biggest success so far seems to be for Lake County, with a combination of the most additions and deletions. The Utility of Our Inputs

Next Steps Wait to hear from the Census Bureau on efficacy of test Likely that State Data Centers will be allowed to participate at this level, along with the other responsibilities they have Improvements will likely come from the assistance we can provide to the most important source – local government and their GIS departments.

And watch for LUCA Not Luca Brasi! Local Update of Census Addresses Testing is going on now for the 2006 Census test sites in NC and CA
