Population Estimates for 2004: Indiana Barely Maintains Its RankIndiana’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

$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 $27,000
100 $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 103-430) 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
