Major Components of 2010 Census
Address List Development
2010 Address Canvassing Facts
• 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
• 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
• $$$! 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
1: Establish quantitative
measures of
address and spatial data
3: Monitor
and Improve
the quality
of the:
2: Assign Quality
Indicators to
output from
the MTDB
IT processes

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-todate 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
• 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
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
• 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
What Kind of Street Feature Data?
• Street centerline geometry
• Street attributes – names, address ranges, etc.
• Expand Census centerline and attribute coverage
• Spatially-correct misaligned streets in conjunction with
high-quality imagery
