2020 Census LUCA Operation Frequently Asked Questions from the U.S. Census Bureau website
Q: What is the role of Regional Planning Commissions?
A: Since Regional Planning Commissions are non-governing organizations, the Regional Planning Commissions (RPCs) cannot participate directly in LUCA, unless authorized by a functioning government.
Q: While reviewing the Census Bureau's address list, if the LUCA participant notices multi-unit address records are missing and need to be added, but the local source does not clearly define the individual unit (sub-address) information, how should the participant proceed?
A: All reasonable effort should be taken to provide the actual sub-address information. Without individual unit information for multi-unit records, the Census Bureau will not be able to process the record for inclusion in the 2020 Census.
Q: While reviewing the Census Bureau's address list, if the LUCA participant believes the sub-addresses of multi-unit records are incorrect, but their source does not include the actual sub-address, how should the participant proceed?
A: If the participant does not have a local source that identifies the actual sub-addresses, they should not edit the address records in question.
Q: How much time and money should a municipality expect to spend on the LUCA review?
A: It will differ for each locality depending on the geographic area, number of addresses, and technical resources available, but you can expect that the effort will be substantial.
Q: What are some challenges with using utility files?
A: Utility files may not identify multiple units. Multiple entrances may not equal the number of apartments. In addition, there may be an extra entrance for “common areas” such as the cellar, hallways, etc.
Q: What software will LUCA reviewers use for validation of addresses?
A: Geographic Update Partnership Software (GUPS). GUPS is based on an open-source platform known as QGIS. It is a customized geographic information system (GIS) provided by the U.S. Census Bureau.
Q: Will the Geographic Update Partnership Software (GUPS) autocomplete street names?
A: It will not autocomplete. You will, however, have ability to import your address list (in .CSV or .txt format) and match your fields to the Census Bureau's address fields.
Q: Has the Census Bureau prepared guidelines that may be provided to an MIS or IT Department regarding the level of security required to use the GUPS?
A: The New York Regional Office is getting more specific guidelines. In the interim, Confidentiality and Security Guidelines booklet D-2004.pdf, specifically Section 4.1, outlines the basics of what the U.S. Census Bureau asks a government IT Department to do to secure the Title 13 data and applies to both the GUPS option as well as the Digital option. For more assistance contact the LUCA helpdesk at 1-844-344-0169.
Q: What is the hierarchy of LUCA submissions, does one local entity get priority over another when there is a conflict in submissions?
A: There is no hierarchy to the LUCA submissions. The U.S. Census Bureau will process each submission individually.
Q: Does the U.S. Census Bureau provide reasons when addresses that local entities submit are rejected?
A: The Census Bureau will be providing Feedback to partners that participate in LUCA. The Census Bureau will provide feedback codes for each action, as well as the list of addresses the Census Bureau will be including for enumeration.
Q: What layout should be used for address updates sent to the Census Bureau?
A: The file layout that should be used is located here https://www2.census.gov/geo/pdfs/partnerships/luca/Stateside_ElectronicAddressList_LegalValues.pdf
Q: If your area has more than 300,000 addresses can you still use GUPS by breaking the addresses into smaller lists?
A: Yes, you can parse your addresses into smaller lists before bringing them into GUPS. Instructions will be available on the Census website.
Q: When will the 2020 Census Local Update of Census Addresses Operation (LUCA) Respondent Guide be available?
A: The guide will be distributed along with the LUCA material, it will not be available ahead of time. It will also be posted on the Census Bureau web-site around that time, no specific date is available.
