Topics
Background and progress on The Geographic Support System Initiative (GSS-I)
Update on the 2020 Local Update of Census Address (LUCA) program
The GSS-I Partnership Program
Opportunity for tribal, state, county, and local governments to continually exchange address & spatial data with the Census Bureau
Recognizes partner governments as a definitive authority for quality address and street data within their communities

What is the Basic Process?1. Acquire partner data and perform Content Verification
to determine general usability2. Crosswalk, standardize, match, and geocode partner
addresses and structure points using the Master Address File (MAF)
3. Match street centerline data to identify differences, calculate spatial accuracy (CE95 method) of partner data using GPS control points
4. Ideal Scenario: new addresses are added to the MAF, new streets are added to TIGER, address and spatial inconsistencies are submitted for resolution

Key Components of the GSS-IAn integrated program that utilizes a partnership program for:
– Improved address coverage
– transaction-based address and spatial feature updates
– Enhanced quality assessment and measurement

Reengineering Address Canvassing
In-office and In-field work MAF/TIGER updates from GSS-I Maximizing the use of the DSF Research and use other sources of
addresses, including administrative records and commercial data

2020 Census Local Update of Census Addresses (LUCA)
Program
Background
LUCA 1998/99: First opportunity for tribal and local governments to review and update the Census Bureau’s address list.
2010 LUCA: Based on Census 2000 feedback, three participation options were offered:
Option 1: Title-13 Full Address List Review (similar to LUCA 1998)
Option 2: Title-13 review, full address list submission Partners provide their entire residential address list with access to Title-
13 addresses Option 3: Non-Title-13, full address list submission
Partners provide their entire residential address list without access to Title- 13 addresses

2020 LUCA Improvement Research
To develop potential alternative designs for LUCA 2020 based on research by four subteams• Looking Back at 2010 (assessments, surveys,
lessons learned)• Impact of Geographic Support System Initiative (GSS-I)
on LUCA (utilizing address data, software and processes for LUCA)
• Reengineered Address Canvassing’s impact on LUCA (in- office validation)
• Focus Groups
15
LUCA Recommendations 1. Continue the 2010 Census LUCA Program improvements that
were successful• Continue to provide a 120-day review time for participants.• Continue the six month advance notice about the LUCA
program registration• Continue a comprehensive communication program with
participants• Continue to provide a variety of LUCA media types• Continue to improve the partnership software application• Continue State participation in the LUCA program
2. Eliminate the full address list submission options that were available in 2010 LUCA (Options 2 and 3). This will:• Reduce the number of deleted LUCA records in field
verification activities• Reduce the burden and cost of processing addresses and LUCA
address validation
16
LUCA Recommendations (continued)
3. Reduce the complexity of the Local Update of Census Addresses Program
4. Include census housing unit location coordinates in the census address list and allow partners to return their housing unit location coordinates aspart of their submission
5. Provide any ungeocoded United States Postal Service Delivery Sequence File addresses to State and County partners
6. Provide the address list in more standard formats
7. Conduct an in-office validation of LUCA submitted addresses
8. Utilize GSS-I data and tools to validate LUCA submissions
17
9. Encourage governments at the lowest level to work with higher-level governments to consolidate their submission.
10.Eliminate the Block Count Challenge
11.Eliminate the use of the asterisk (*) designation for multi-units submitted without unit designations
12.Encourage LUCA participants to identify addresses used for mailing, location, or both
LUCA Recommendations (continued)
10
Current Activities/Next Steps
Investigate the technical recommendations for 2020 LUCA:• Use of background imagery on paper maps• Ability to provide structure locations within LUCA
materials• Feasibility of web based registration
Determine feasibility of using areas where we have planned field activities to validate LUCA records
Work with OMB to develop a 2020 LUCA Appeals process
