2010 Census Local Update of Census Addresses (LUCA) Program
Feedback Overview
Overview

Overview
The Local Update of Census Addresses (LUCA) program is an integral part of
the 2010 Decennial Census activities that utilizes the expertise of selected
tribal, state, and local governments to improve the accuracy and completeness
of the address list used to take the census.
In accordance with the Census Address List Improvement Act of 1994, Public
Law 103-430, the feedback phase of the LUCA program provides
participating governments with detailed feedback materials that document
which local address additions and updates the Census Bureau accepted or did
not accept. Your review of the feedback materials is voluntary.
You may direct general questions about the content and review of the
feedback materials to your Census Bureau Regional Census Center toll free at
1-866-511-LUCA (5822). For technical assistance about computer
applications including the MAF/TIGER Partnership Software (MTPS), please
call the LUCA Technical Help Desk toll free at 1-866-919-LUCA (5822).

2010 Census Local Update of Census Addresses (LUCA) Program
Feedback Materials – Overview

For Option 3 participants, the Census Bureau provides the following materials:
1. Feedback Address Update Summary Report – displays the original
number of addresses on the Census Bureau’s address list for the
participant’s jurisdiction, the total number of addresses submitted by the
participant, and the current number of addresses within the participant’s
jurisdiction.
2. Maps (paper or shapefiles) – paper maps or shapefiles may include
feature updates provided by you, other LUCA participants, and/or other
updates found by the Census Bureau during the Address Canvassing
operation.
a. Map Sheet to Block Number Relationship List (for use with
paper maps) – identifies the map sheet or sheets on which each
census block is located and is sorted by census tract number and
census block number in ascending order.
or
b. Readme file (for use with shapefiles)
Census Entity Codes – Local Governments
All local government entity codes appearing on the feedback materials have a
two-letter code identifying the type of entity – ST (state), CO (county), PL
(place), or MC (minor civil division). County, place, and minor civil division
codes include the state 2-digit FIPS numeric code. Minor civil division codes
also include the county code. For example:
State:
County:
Place:
MCD:

ST61
CO61923 (state and county codes)
PL6144444 (state and place codes; county not shown)
MC6192355555 (state, county, and MCD codes)

Census Block Number Differences Between Initial LUCA Products and
LUCA Feedback Products
You may find a difference between the census block numbers on your initial
LUCA products and your LUCA feedback products. Because the addition of
new roads and/or boundary updates can subdivide census blocks, the Census
Bureau has continually updated its database since Census 2000.
The newly created census blocks are assigned a 4-digit “parent” number block
number (i.e., 1101) plus an alphabetic suffix (i.e., 1101A). This is why some
census blocks on your initial LUCA materials had suffixes.
For instance, Figure 2.2 shows “parent” block 1101 on the initial LUCA
materials contained blocks 1101A, 1101B, 1101E, 1101F in ‘Any City’ and
blocks 1101C, 1101D within ‘Any County’ but outside of ‘Any City’.
Note that LUCA participant ‘Any City’ received addresses only for those census
blocks located within its jurisdiction, i.e. 1101A, 1101B, 1101E, and 1101F.
Census blocks 1101C and 1101D are located outside of ‘Any City’ in ‘Any
County’.

Chapter 1
2010 Census Local Update of Census Addresses (LUCA) Program
Feedback Materials – Overview

This process of adding roads and updating boundaries has continued since you
received your initial LUCA materials. Some blocks may now be numbered
differently in your feedback materials than they were on your initial LUCA
materials. Some formerly unsuffixed blocks now have suffixes, while some
formerly suffixed blocks may have been further subdivided.
Note in Figure 2.3 how resuffixing occurred because of a boundary change by
‘Any City’, and also the addition of Willow Street. The computer algorithm
that assigns suffixed block numbers does not attempt to preserve the old suffixed
numbers for the portions of the original “parent” block number even when they
are unaffected by a new road or boundary. Thus, in Figure 2.3 the census block
bounded by Elm St., Oak St., and 1st Ave. now is numbered 1101E but
corresponds exactly to the former block 1101A. The original blocks 1101D,
1101E, and 1101F are now completely reconfigured and numbered 1101A,
1001B, 1101F, and 1101G.
‘Any City’ would receive feedback materials containing addresses only for those
census blocks located within their jurisdiction, i.e. 1101A, 1101B, 1101D,
1101E, 1101F, and 1101G. Census block 1101C is located outside of ‘Any
City’ in ‘Any County.’

Glossary
American Indian area – A Census Bureau term that refers to any or all of the following
entities: American Indian reservation, American Indian off-reservation trust land,
Oklahoma tribal statistical area, joint use area, American Indian tribal subdivision, tribal
designated statistical area, and state designated American Indian statistical area.
American Indian off-reservation trust land – The United States holds title for specific
areas in trust for the benefit of federally recognized American Indian tribes (tribal trust
land) or for individual American Indians (individual trust land). Although trust land may
be located on or off a reservation, the Census Bureau recognizes and tabulates data only for
off-reservation trust land. Census data always associate off-reservation trust land with a
specific federally recognized reservation or tribal government.
American Indian reservation – A federal American Indian reservation is an area that has
been set aside by the United States for the use of one or more federally recognized
American Indian Tribes. It covers territory over which a tribe(s) has primary governmental
authority. Its boundary is defined by tribal treaty, agreement, executive or secretarial order,
federal statute, or judicial determination. A state American Indian reservation is an area
that a state government has allocated to a tribe recognized by that state, but not by the
federal government.
Census Bureau Address List – A nationwide list of all housing unit and group quarter
addresses known to the Census Bureau. In addition to the mailing address and ZIP Code,
the address list may identify the location of each housing unit and group quarters.
Census block – A geographic area bounded by visible features, such as streets, roads,
streams, and railroad tracks, and invisible features, such as the boundaries of governmental
units and other legal entities. A census block is the smallest area for which the Census
Bureau collects and tabulates statistical information. Census blocks are numbered within
census tracts and are unique to the census tract to which they belong.
Census block number – Census block numbers may contain a 4-digit number plus a 1digit alpha character, if applicable, e.g. 3001A. Suffixes, such as 2011A and 2011B, reflect
boundary changes as well as added features. See tabulation block.
Census tract – A small relatively permanent statistical division of a county or statistically
equivalent entity, delineated for the purpose of presenting Census Bureau statistical data.
Census tracts never cross the boundary of a county or statistically equivalent entity, but
may split other geographic entities; e.g., minor civil divisions and places.
Census tract number – Unique numbers to identify census tracts within a county or
statistically equivalent entity. Census tract numbers contain up to a 4-digit number
followed by a decimal point and a 2-digit number for suffixed tracts, e.g., 1234.01. For
census tracts without a suffix, the number will contain a period with zero fill, e.g., 4567.00.
Leading zeros are not shown on Census Bureau maps.
City-style address – An address that consists of a house number and street name; for
example, 201 Oak Street. The address may or may not be used for the delivery of mail and
may include apartment number/designations or similar identifiers.

16

Glossary

Confidentiality – The guarantee made by lay (title 13, United States Code) to individuals
who provide information about themselves or their business to the Census Bureau. This
item refers to the Census Bureau’s promise of nondisclosure of that information to others.
Feature – Any part of the landscape, whether natural (a stream or ridge) or artificial (a road
or power line). In a geographic context, features are any part of the landscape portrayed on
a map, including nonvisible boundaries of legal entities, such as, city limits or county lines.
Geocodes – Codes that place an individual address in its correct geographic location, which
includes the correct state, county, census tract, and census block codes.
Group quarters (GQ) – A place where people live or stay, in a group living arrangement,
that is owned or managed by an entity or organization providing housing and/or services for
the residents. This is not a typical household-type living arrangement. These services may
include custodial or medical care as well as other types of assistance, and residency is
commonly restricted to those receiving these services. People living in group quarters are
usually not related to each other.
Housing unit (HU) – A single-family house, townhouse, mobile home, trailer, apartment,
group of rooms, or a single room occupied as a separate living quarters or, if vacant,
intended for occupancy as a separate living quarters. A separate living quarters is one in
which one or more occupants (or intended occupants, if vacant) live separate from any
other individual(s) in the building and have direct access to the living quarters without
going through another living quarters, such as from outside the building or through a
common hall.
Legal boundary – The legally defined boundary of a governmental unit, usually referring
to a county, minor civil division, or incorporated place. The legal boundary identifies the
area within a tribal government’s jurisdiction, and thus bounds the area of LUCA
responsibility.
Master Address File (MAF) – A nationwide database of all addresses to support many of
the Census Bureau’s operations. Besides containing mailing addresses and ZIP Codes, a
MAF record also contains geographic information about the location of addresses. Now a
part of the MAF/TIGER Database.
Noncity-style address – An address that does not have a house number and/or street name
or may not include a complete house number and street name address. This includes rural
route and box number address and highway contract route addresses, etc., which may
include a box number, post office boxes and drawers, and general delivery.
Other living quarters – An OLQ is a place where people could live or stay that is
normally owned or managed by an entity or organization providing services or care for the
residents. The Census Bureau verifies OLQs as Group Quarters (GQ) during a separate
field operation.
Place – A concentration of population either legally bound as an incorporated place or
identified by the Census Bureau as a census designated place.
Shapefile – Data set used to represent geographic features such as streets and boundaries.
Shapefiles can represent point, line, or are features and require GIS or mapping software.

Glossary

17

Structure point – A dot on a Census Bureau map, used to show the location of one or more
living quarters. A 4-digit number plus 1-digit alpha character assigned within a census
block to each structure point. Structure points are stored in the TIGER®.
Tabulation block – The smallest area for which the Census Bureau provides decennial
census data. A tabulation block cannot be split by the boundary of any legal or statistical
entity recognized by the Census Bureau for data presentation.
Title 13, U.S.C. – Provides for the confidential treatment of census-related information,
including individual addresses and map structure points. Title 13 requires that all liaisons,
reviewers, and anyone with access to Title 13 abide by the Confidentiality and Security
Guidelines. Title 13 also requires that the Census Bureau maintain the confidentiality for
all of the information that it collects.
Topologically Integrated Geographic Encoding and Referencing (TIGER®) – A
