Census Geographic Support – Census Geographic Support – Major Initiatives Over TimeMajor Initiatives Over Time
What is the GSS-I?What is the GSS-I?
Improved address coverageContinual address and spatial database updatesEnhanced quality assessment and measurementImproved Partnerships
Why the GSS Initiative?Why the GSS Initiative?Recommendations of our stakeholder and oversight communities (GAO, OIG, NAS): Lack of a comprehensive geographic update program between censuses
Associated negative impact on ongoing programs such as the American Community Survey, other current surveys, and
small areas estimates programs
Supports a targeted Address Canvassing for 2020 Census2015
Major Components of 2010 Census Major Components of 2010 Census Address List DevelopmentAddress List Development
Full Address Canvassing is VERY expensive:
•Addresses to be verified: 145 million •Census workers hired: 140,000 •Hand-held computers: 151,000 •Local Census Offices managing operations: 151 •Operational Dates: March 30 - July 2009
Why “Targeted” Address Why “Targeted” Address Canvassing?Canvassing?
Goal: develop on-going update and change detection processes
Target only areas with uncertaintyQuality of Addresses
Currency of Addresses
Hinges on establishing an acceptable address list for each level of government
GSS-I Goal:GSS-I Goal:Address Coverage Address Coverage
• Complete and current address coverage• Additional emphasis on change detection• Expanded address sources for MAF update, especially
in areas without city-style addresses• American Community Survey (ACS) and current surveys
need current and complete coverage

URISA, NENA, and NAPSG• YOU
What’s in it for you?What’s in it for you?• Improved address and feature coverage
(local govts are authoritative source)support current survey samples, including the American Community Survey
• More current data and improved process flowsshould minimize the impact of programs like LUCA
• Taxpayer savings (targeted ADCAN)
• Accurate 2020 Census • Our evaluations & feedback may help you
improve your data

Minimum Address GuidelinesMinimum Address Guidelineshttp://www.census.gov/geo/www/gss/gdlns/addgdln.html
Minimum Address AssumptionsMinimum Address Assumptions
Sample rules for acceptable addresses:• All required fields must have data
Address Number, Street Name, and ZIP Code OR Tract/Block OR City/State
• Must meet predefined business rulesEx: ZIP Code is numeric, five digits
• If two or more addresses have the same house number, street name and ZIP, then one of them must have an additional address element (i.e., unit designator, such as Apt 101)
Address MetadataAddress Metadata• In addition to the standard FGDC Address Standard
metadata, we would like to collect:
• What is the source of the address (assessor, utility, emergency management)?
• Is the address used for mailing and/or locating the structure? • Is the address for a Group Quarters (prison, college dorm)?• What type of structure does the address represent (single-family
home, trailer, multi-unit apartment building)?• Is it a commercial, residential, or other type of address?• When was the house built and/or addressed?

• BAS: January 1st of each year• Many entities still participating on paper
boundaries, relatively correct• (Most) counties can participate digitally• Have you reviewed the boundaries for
accuracy? (MTAIP Realignment!)
