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 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!

Moved to end, hid background so it's not distracting from graphic. I think on a large screen it's fine to have the slide oriented this way but it's better on a solid background.
