Diverse America and Much More
With Census 2000, users have a special
opportunity to study the heritage of
America’s population. Summary File (SF) 4
gives users access to extensive detail on
the socioeconomic and housing
characteristics of the nation’s race,
Hispanic, ancestry, and tribal groups. In
the past, this file has been large, complex,
and expensive. The Census 2000 version
is still large, but advances in software,
online access, and compression technology
have made this file accessible to many new
users who did not have access in the past.
All summary files are useful in studying the
demographic makeup of the population, but
SF 4 is the most detailed Census 2000 file
and the only file to offer so many different
kinds of data for the broad array of groups
in our population.
Data in SF 4 Are Based on the
Census 2000 Sample Questions
The SF 4 data are drawn from responses to
questions asked on the Census 2000 long
form (the sample questionnaire).  Although
the sampling rate varied according to the
population density of particular areas,
generally the long form went to one in six
households; in processing and tabulating
the data, the Census Bureau adds weights,
so that the data reflect trends in the entire
population.
How many of the Hispanic homeowners in
your community are Mexican?  What is their
median family income?  What percentage of
their income goes for housing? Are their
occupations different from those of the
Cuban or Puerto Rican population in your
area?  What are the demographics of the
Irish population in the United States?
Naturalized citizens?  And what are the
Figure 1.
Census 2000 Gateway
Your “gateway” to Census 2000 is http://www.census.gov/main/www/
cen2000.html. The gateway page on the Census Bureau’s Web site gives
you one-stop access to Census 2000 data files (such as Summary File 4)
and information about the way we conducted the census, the data release
schedule, the various data products, and all you need to understand and
use data from the census.

characteristics of various groups
living on American Indian
reservations? SF 4 provides answers
to questions about these and many
other groups.
SF 4 is the last in a series of sum-
mary files (SF 1, SF 2, and SF 3
preceded it). SF 1 has 286 tables
based on the short form questions
asked in the census, with data for
areas as small as census blocks. SF
2 has a subset of the tables found in
SF 1, with tables repeated for up to
249 race and Hispanic groups,
provided they meet a population
threshold. SF 3 provides data from
the sample or long form questions.
It is notable because it has over 800
tables, with detail down to the level
of block groups.
SF 4 is similar to SF 2. It lets you
show characteristics for up to 335
race, Hispanic or Latino, and
ancestry groups, provided they
meet certain population thresholds.
Special Feature: Abundant
Data on Race, Hispanic, and
Ancestry Groups in SF 4
SF 4 contains 323 detailed tables—
213 population tables and 110
housing tables. Figure 2 lists the
subjects.  There are two kinds of
tables: population (PCT) tables, with
data on education, income,
employment, commuting, citizenship
status, family and household
characteristics, and other topics;
and housing (HCT) tables, with data
on the physical and financial
characteristics of occupied housing
units, along with information on the
householder.
In Census 2000, Americans were,
for the first time, allowed to select
more than one race. In addition,
the census included a question on
Hispanic or Latino origin, with a
provision that respondents identify
their specific origin (e.g., Cuban).
Finally, the long form included a
question on ancestry. These three
questions, along with the question
on place of birth, give users a full
view of America’s diverse heritage.

SF 4 allows users to study the
demographic mix for small areas.
For any given area down to the level
of census tract, tables may be
repeated for 335 race, ethnic, and
ancestry groups including—
• 132 race groups, including
iterations for multirace groups.
• 38 specific Asian groups (included
in 132 race groups).
• 20 specific Native Hawaiian and
other Pacific Islander groups
(included in 132 race groups).
• 78 specific American Indian and
Alaska Native tribe categories
(reflecting 39 tribes).
• 25 Hispanic groups and 14 “Not
Hispanic or Latino” groups.
• 86 ancestry groups.
Working With Population
Thresholds in Summary File 4
Tables in SF 4 can be shown for a
particular population subgroup if the
group meets two thresholds:
1.  SF 4 repeats a table for a race
 or a Hispanic or Latino origin group
(such as Salvadoran) if the group
has 100 or more persons in the
geographic area of interest.
2.  SF 4 repeats a table for a race,
Hispanic or Latino, or ancestry
group (such as Arab or Irish) if the
group has 50 unweighted cases
in the sample. The final table always
displays weighted numbers, so in
a specific area there must be 50
people times the appropriate
weight.
If, for example, a county has 100 or
more “Vietnamese alone,” and the
census sample had 50 or more
sample unweighted cases of
“Vietnamese alone” in the county,
then all the SF 4 tables for that area
are shown for “Vietnamese alone.”
Appendix 1 in this profile lists the
groups for which tables may be
repeated in SF 4. A reference like
“Vietnamese alone” identifies people
who selected one race on their
census questionnaire. The reference
“Vietnamese alone or in any
combination” identifies all those who
selected “Vietnamese” as their race—
both those who selected just one
race and those who selected this
race, plus one or more other races.
You should note that you can get
simple population totals for these
groups in other files—most notably
SF 1 for race and Hispanic subgroups
and SF 3 for ancestry groups.
Although SF 4, for example, will not
let you display the characteristics of
Asian Indians in the tracts of
Lancaster County, in SF 1, you can
nonetheless find the total number of
Asian Indians living in the tracts, but
nothing more.
This applies to ancestry too. SF 3 has
several tables listing the totals for
110 ancestries, with data down to
the level of census tracts. In the case
that a particular group does not meet
the SF 4 threshold, you can still
get a count of the ancestry group in
SF 3.
Other Highlights in SF 4
Summary File 4 is very similar in
design to Summary File 2: its
purpose is to allow users to display
tables already published in a
previous file for smaller population
groups. Many of the SF 4 tables
appear in SF 3; in SF 4, you can
display these tables for any of the
335 groups that meet the criteria.
All the housing (HCT) tables found in
SF 4 were released in SF 3. Most of
the population (PCT) tables in
SF 4 are in SF 3. There are, how-
ever, other tables in SF 4 that users
cannot get in SF 3. Appendix 2 lists
the tables unique to SF 4.
One particular bonus: SF 4 has
detailed data on 102 industries
(PCT85) and 125 occupations
(PCT86); SF 3 has  less detailed data
for industry and occupation.
If you need to know the number
of electricians in Maine, you cannot
find the answer in SF 3, you must go
to SF 4.
Geography in SF 4
Like all summary files, Summary
File 4 is packed with data for many
geographic areas. It serves users
interested in the macro view (for
example, the United States as a
whole or entire states) and the micro
view (census tracts), as well as all
areas in between.
SF 4 gives you a summary of
geographic areas (all census tracts in
a county) or parts of areas (for
example, part of an Indian
reservation within a state).
Reference Sources
If you are making extensive use of the race, Hispanic or Latino, ancestry, and tribal data, be sure to consult
the discussion of “Race,” “Hispanic or Latino,” and “Ancestry” in Appendix B (“Definitions of Subject Character-
istics”) of the SF 4 technical documentation online at http://www.census.gov/prod/cen2000/doc/sf4.pdf.
Race and Hispanic definitions used by the Census Bureau conform to the standards published in the October
30, 1997 Federal Register notice entitled “Revisions to the Standards for the Classification of Federal Data on
Race and Ethnicity” online at http://www.census.gov/population/www/socdemo/race/Ombdir15.html issued
by the Office of Management and Budget. These standards govern the categories used to collect and present
federal data on race and ethnicity. More background, FAQs, and historical data can be found on the Census
Bureau Web site http://www.census.gov/population/www/socdemo/race.html.

American FactFinder® Lets You Select Detailed Data From Summary
File 4 for Race, Ethnic, and Ancestry Groups
At the right, we show Table PCT44. Sex by Age
by Citizenship Status, from SF 4, for people in
Hawaiian counties who identified themselves as
“Native Hawaiian alone or in any combination.”
SF 4 shows a table for a group only if the group
numbers 100 or more people and has 50 or
more unweighted cases of this group in the
sample for that area. All four counties in Hawaii
meet the thresholds for this group, so Table
PCT44 (and all tables in SF 4) can be shown for
this group. Had we chosen “Asian Indian alone
or in any combination,” the results would have
been much different: only two counties meet the
threshold for this group and consequently SF 4
tables for this group can be repeated only in
these two counties.
First, go into FactFinder, select
“Data Sets,”  Summary File 4, and
then “Detailed Tables.”
FactFinder leads you through the
selection of one or more geographic
areas – all the way down to the
census tract. Then it prompts you to
select one or more detailed tables
from SF 4.
Here we selected counties in Hawaii
as our geography and chose Table
PCT44, Sex by Age by Citizenship
Status. Once you select the geo-
graphy and the table, FactFinder
prompts you with a list of groups to
select. You are then able to select
from 249 race, ethnic, and tribal
groups, and 86 ancestry groups.
FactFinder will display Table PCT44
for that group.

By far the easiest way to access
the data is through the American
FactFinder®. The Census Bureau has
also released these files on CD-ROM
and DVD and people working with
data on disc will find the geographic
arrangement discussed below.
State files.  Summary File 4 was
released on CD-ROM as a series of
state files, with files for the District of
Columbia and Puerto Rico. The table
designs are standard for each kind of
geographic area. These files have all
substate geographic areas down to
the level of census tracts.
Additional releases included  all the
state files on five DVDs; the DVD
product called the U.S. Summary
provided the data for all substate
areas. Both the CD-ROMs and the
DVDs come with software for
accessing and downloading the data.
(ASCII versions of the files are
available online and on DVD.)
National file. The National File on
four DVDs provides summaries for
higher levels of geography (places
and above) and covers the entire
country. This file is designed for
users who need to produce national
or regional summaries of an area
(e.g., all metro areas in the country),
but do not need the data for really
small areas such as census tracts.
Users will find it easier to generate
these figures using the National File
rather than the individual state files
on CD-ROM or the U.S. Summary file
on DVD.
The National File also has totals for
multistate areas like metro areas or
American Indian reservations. If you
were using the U.S. Summary DVD
(see above), you could select the
components of these areas (e.g., all
states in the East region), down-load
them as a single file, and then easily
compute a total. Nonetheless, the
easiest way to generate data for
these areas is through the National
File.
Internet Access Through
American FactFinder®
Visit the Census Bureau’s award-
winning homepage http://
www.census.gov and click on the
American FactFinder® (AFF) for
access to as much or as little data
as you need from SF 4. AFF gives
several easy-to-use options for using
SF 4:
• Detailed Tables gives you direct
access to all the SF 4 tables. As
Figure 3 shows, you must go to the
“Change Selections” option in the
blue bar to select the SF 4 race or
ethnic group (for example,
Cubans) or ancestry group (for
example, Arabs) for which you
wish to repeat a table. Once you
click on “Race or Ethnic Groups”or
“Ancestry Groups,” AFF allows you
to pick the group.
• Quick Tables gives you a set of key
variables for areas as small as
census tracts. In most cases, you
can repeat tables for the 335
groups that meet the population
thresholds.
• Geographic Comparison Tables
(GCT) lets you see how your state,
city, county, metro area, or census
tract stacks up in comparison to
others according to key variables.

When to Use SF 2, When to Use SF 4
The long form was sent to a sample of the population, and the answers of these respondents have been given
weights to produce estimates for the total population. Particularly in small places (for example, small cities),
census tracts, and block groups, users may observe differences in the population and housing totals shown in
SFs 1 and 2 and SFs 3 and 4.
Based on the short form, the SF 1 and SF 2 tables provide the official census count of the number of people in an
area. Based on the long form, the SF 3 and SF 4 tables provide estimates of the characteristics of the total
population.
When dealing with items collected on the short form (for example, total population, the number of people
reporting their race or Hispanic origin, the number of housing units, or the number of owners and renters), users
should always view the SF 1 and SF 2 numbers as the official count. For more information, see Data Note 2 in the
SF 4 technical documentation.

Using GCTs,  you cannot repeat
tables for the 335 groups, only
for the 9 major race groups:
White alone; Black or African
American alone; American Indian
or Alaska Native alone; Asian
alone; Native Hawaiian and other
Pacific Islander alone; Some Other
Race alone; Two or More Races;
Hispanic or Latino; and White
alone, not Hispanic or Latino.
• Custom Tables lets you select and
display simple tabulations from
more complicated tables or to
mingle tabulations from several
tables in one table. It also lets you
create a table from several source
tables and display the same table
for any of the 335 groups that
meet the criteria.
AFF also gives you access to the
technical documentation and other
reference information to assist you
in using the file. Be sure to look at
the Summary File 4 overview page
http://www.census.gov/Press-
Release/www/2003/SF4.html for
links to the documentation, the File
Transfer Protocol (FTP) site, and
other useful pages. Especially
valuable on this page is a search
tool that lets you access Census
2000 and related data for each
state.
Download Data From
American FactFinder®
via File Transfer Protocol
(FTP)
Every AFF data page has a
“Download” tab through which you
can download files as .csv, tab-
delimited, or rich text format files
either directly or indirectly into a
spreadsheet program like Excel or
Lotus or a database program like
Access or dBASE.
In addition, ASCII files in a zipped
format are available free on the
Internet via File Transfer Protocol
(FTP). Note that these files do not
come with viewing software. Given
the size of the files, the speed of
your modem and Internet connec-
tion, downloading a file may be a
time-consuming process. If you plan
on downloading or using the ASCII
files, be sure to consult the “Read
Me” file on the Internet http://
www2.census.gov/census_2000
/datasets/Summary_File_4
/0README_SF4.txt.
Unfortunately,  technical support for
the ASCII files is unavailable.
However, there is a helpful set of
instructions for downloading the ASCII
files into a data base application at
http://www.census.gov/support/
SF4ASCII.html.
Buy SF 4 on CD-ROM or DVD
If you plan to make heavy use of
SF 4 or to analyze data for more than
a few variables, you may want to
consider purchasing the SF 4
data on CD-ROM or DVD. You may
purchase discs from the Census
Bureau’s Customer Services Center at
301-763-INFO (4636).
The files on disc come with pro-
prietary software that operate on
computers with Microsoft Windows
95/98/2000/NT/ME/XP. The
software provides an expandable
hierarchical menu or equivalent for
the selection of one or more
geographic areas. The user software
supports selection of individual data
items, complete data tables, and
geographic identifiers to include in
output files. Figure 4 shows how to
download and display SF 4 data from
a disc.
As the order form shows on page 12,
there are three kinds of discs, with
access and retrieval software:
• State files on CD-ROM or in a few
cases (e.g., Florida) on DVD.
• U.S. Summary Files on DVD. This
product has all the state files on
disc. This would be the best buy
for someone needing tract data for
the entire country.
• National File on DVD. This product
has data for the larger areas in the
country (places and larger areas).
This is the best option for
someone who does not need data
at the census tract level or
someone needing substantial data
for “macro” areas in the country
(e.g., regions and divisions).
Census 2000 Maps
Particularly if you are planning to
use data for census tracts, you’ll
need Census 2000 maps, available
electronically on the Internet (in pdf)
and on paper:
Block maps.  These are detailed
maps (36" x 33") showing all levels
of geography down to the level of
census blocks. They can be pur-
chased from the Customer Services
Center in map sets for counties,
cities, minor civil divisions, and other
areas. These detailed street maps
show the boundaries of blocks and
tracts and all larger geographic
areas. To view these maps online,
go to http://www.census.gov/geo
/www/maps/CP_MapProducts.htm.
Census tract outline maps.  Far
less detailed than the block maps,
the outline maps (36" x 33") show
the boundaries of census tracts,
ideal for most users. Streets are
shown where they coincide with tract
or political boundaries. They are
available for sale by county from the
Customer Services Center. To view
these maps online, go to http://
www.census.gov/geo/www/maps
/CP_MapProducts.htm.

Powerful Software on SF 4 CD-ROMs and DVDs Lets You Control
Retrieval and Output
Tallahatchie County, Mississippi, is a
small rural county (pop: 14,903) in
the northwestern part of the state,
where almost 60 percent of the
population is Black or African
American.
Suppose you would like to profile this
population, a perfect use of SF 4. In
using the SF 4 CD-ROM, first you
would install the software and select
the files for the “Black alone” and the
“Black alone or in combination with
other races.”
Next, you would pick the geography
you want–in this case, all four tracts
in the county–and then the software
prompts you to pick a table–in this
case, Table HCT089, Tenure by
Poverty Status in 1999 by Age of
Householder.
Screen 1 shows the selection of
geography on the CD-ROM version of
SF 4 for the county; screen 2, the
selection of the data variables. You
then can save the tabulation, and
then open it up in a spreadsheet or
database application.
Note:  All the data for a specific
group are together on one of the
discs in the National File or the U.S.
Summary. You must select a group
from the appropriate disc before
displaying a table for that group.
