• Number of housing unit addresses that needed verification: 145 million
• Number of census workers hired for Address Canvassing: 140,000
• Number of hand-held computers used: 151,000
• Number of local census offices that managed operations: 151
• Dates of operation: March 30 - Mid-July 2009
Goal: A Shift in Focus for the 2020 Census
• From a complete Address Canvassing to a targeted Address Canvassing– Hinges on establishing an acceptable address list for
each level of government

Why a “Targeted” Address Canvassing?
• $$$! It is VERY expensive – Field an ARMY of address canvassers– “Walk” EVERY street in the nation…
• Goal: developing regular update and change detection processes
• Result: “Target” only areas with uncertainty– Quality of Addresses– Currency of Addresses
Quality Assurance Goals
3: Monitor and Improve the quality
of the:
Existing MAF/TIGER
Data
IT processes for updating the MTDB
Geographic products
output from the MTDB
1: Establish quantitative measures of
address and spatial data quality
2: Assign Quality Indicators to
MAF/TIGER data
Partnerships are Key!
• Local governments are the authoritative sources for address and spatial data!
• Expanding our Partnerships is Critical– Key step towards establishing an accurate and up-to-
date address list• The GSS-I Partnership Program seeks government,
organizational, and commercial partners willing to share high-quality data on:– Addresses– Housing Unit Structures– Street Centerlines and Attributes
What Kind of Address Data?
• City-style addresses
and/or• Non city-style addresses (i.e., Rural Route #)
that “ideally” meet:
1. USPS minimum delivery requirements, and 2. The FGDC Address Standard (U.S. Thoroughfare, Landmark, and Postal
Address Data Standard)
See the Draft Census Bureau Address Data Content Guidelines:http://www.census.gov/geo/www/gss/gdlns/addgdln.html
What Kind of Housing Unit Structure Data?
• Latitude/Longitude Coordinates for a Housing Unit structure or access point (i.e., from E-911 or Next-Gen E-911 database)
• Structure centroids• Latitude/Longitude Coordinates for a real property parcel or
parcel centroid• Other points used by partner?
See the Draft Census Bureau Address Data Content Guidelines:http://www.census.gov/geo/www/gss/gdlns/addgdln.html
What Kind of Street Feature Data?
• Street centerline geometry• Street attributes – names, address ranges, etc.
Why?• Expand Census centerline and attribute coverage• Spatially-correct misaligned streets in conjunction with
high-quality imagery

GSS-I Progress in last year • Pilot projects from Address Summit (Sept. 2011)
• Address Authority Outreach and Data Sharing• FGDC Address Standards and Implementation• Federal/State/Tribal/Local Address Coordination• Data Sharing Model– Local/State/USPS/Census• Hidden/Hard to Capture Addresses
• Researched/acquired “test” county data for development of GSS-I processing systems. In AL: Bullock and Shelby.
Community TIGER
• New tool being developed in partnership with ESRI.
• Web-based data sharing/upload system.• Open for all to use; no software license
requirements.• Input of state/local/tribal data produces
standardized output format used to update MAF/TIGER.
• Beta version due in Feb 2013.
Planned Schedule
• Fiscal Year 2012 (Oct 2011 – Sept 2012)– Process Development, pilot work, research, system development,
initiated Community TIGER
• October 2012– Kickoff GSS Partnership Program (~51 partners, TBD)
• February 2013– Start Providing Feedback to Partners
• March 2013– Identify 300-400 supplemental FY13 partners based on quality audit of
MAF/TIGER data– Community TIGER beta testing
• October 2013– Planning for open participation!
