LUCA Materials
The Geographic Update Partnership Software (GUPS) is new for
LUCA. The GUPS is a self-contained Geographic Information System
(GIS) update and processing package. In addition to the software, you
will receive the Census Bureau’s address list, address count list by
census block, and Topologically Integrated Geographic
Encoding and Referencing
(TIGER) partnership shapefiles.
The Census Bureau offers its
address list in digital or paper
formats. The digital format
requires the use of spreadsheet or database software. The paper format is available only to governments with 6,000 or fewer addresses.

Preparing for LUCA
You will receive only the addresses
within your jurisdiction’s boundaries
that are currently on file with the
Census Bureau. By participating in
the 2017 Boundary and Annexation
Survey (BAS), you have the opportunity to verify or update your
jurisdiction’s boundaries. Doing this
will ensure that you receive the
complete list of addresses for your
jurisdiction in LUCA.
To prepare your address list before
you receive your LUCA materials:
• Ensure that your address list
contains multiunit structure
identifiers (such as apartment
numbers for individual units)
and that you can distinguish
between residential addresses
and nonresidential addresses.
• Identify local address sources,
such as building permits, E-911
address files, local utility records,
annexation records, and
assessment or taxation files.
• Visit the LUCA Web site or plan
to attend a LUCA promotional
workshop to get more information
about participating in the program.
