SUPPLEMENT NO. 1
PUBLIC USE SAMPLE OF BASIC RECORDS FROM THE 1970 CENSUS:
DESCRIPTION AND TECHNICAL DOCUMENTATION
This supplement to the documentation of the 1970 public use samples pro-
vides a few corrections and other information not available at the time
of the publication.

CORRECTION NOTES
1. TAPE MARKS. Figure 3 on page 10 of the Description and Technical Doc-
umentation incorrectly portrays the positioning of tape marks. There
is no tape mark at the beginning of the file as shown in the documen-
tation. Tape marks immediately following header labels and preceding
trailer labels are correctly shown. At the end of each tape following
the trailer labels are two tape marks instead of one as shown in the
figure.
2. TAPE LABELS. Public use samples contain 120-character logical records
in 1800-character physical records as stated in the documentation.
Header and trailer labels on tapes copied for users incorrectly indi-
cate a logical record size of 1800 characters. The incorrect fields
are characters 11-15 of the HDR2, EOV2 and EOF2 records.
The "File Identifier" on header and trailer labels begins with the
characters "70PUS" followed by the file number. If a system control
card is being used to verify that the correct tape has been mounted it
may be necessary to specify the file identifier enclosed in single
quotes ('70PUS140') since some systems (including IBM 360-OS) assume
that the file identifier or data set name normally begins with an al-
phabetic character.
3. ZERO FILL OF LAST DATA BLOCK ON FILE. Each 1800-character physical
record on the tapes consists of fifteen 120-character logical records.
Since the number of logical records per file is not necessarily a mul-
tiple of 15, there will usually be padding after the last valid logical
record to fill out the physical record, so that a processing difficulty
is not encountered. The padding consists entirely of zeroes, which
should not, of course, be confused with zeroes used as valid codes on
preceding records.
1
S1-2
It will normally be necessary to test for a record type "0" in the
120th character position of each logical record to terminate data
reading, unless the program is testing for a specific geographic code
or limits iteration to the expected number of logical records.
4. ALLOCATION FLAG OMITTED. During production of the samples it was dis-
covered that the allocation of State of residence 5 years ago as de-
termined in the 5% sample was not consistently recorded on the basic
census tapes. Therefore, that allocation flag was omitted from item
P118(5%) (see page 83 of the documentation). Thus, codes 4. 5, 6. and
7 will never appear in that field. P118(5%) still indicates editing
of industry and occupation 5 years ago.
5. NUMBER OF TAPE REELS PER FILE. The public use sample documentation
and tape order forms indicate an estimated number of tapes for each
file. These figures are correct for each State file, and for all but
two of the county group files. Files 220 and 520 (northern plains
area) require two tapes each, instead of one tape each as previously
estimated.
NEIGHBORHOOD CHARACTERISTICS REDEFINITION
CHANGES IN THE LIST OF CHARACTERISTICS
After the publication of the documentation, it became necessary to revise
the production plan for the samples and to derive neighborhood character-
istics from a source other than originally planned. At the same time, it
became possible to include several significant new characteristics in the
record. Among the additions are median family income, index of income
concentration, median years of school completed, the fertility rate for
women 35-44, and intercounty migrants as a proportion of persons 5 years
old and over. Some of the original characteristics had to be modified or
deleted. The list of characteristics appearing on pages 4 thru 9 super-
sedes that of pages 84 thru 89 of the DESCRIPTION AND TECHNICAL DOCUMENTA-
TION.
METHODOLOGICAL NOTE ON WHAT CONSTITUTES A NEIGHBORHOOD
Neighborhood characteristics are presented as meaningful indicators of
the environment in which a sampled household occurs; i.e., ecological
variables. They may be useful in constructing a meaningful typology of
neighborhoods, creating simulations of specific types of communities or
more generally relating person and ecological variables. The critical
user of these characteristics should be aware of the nature of the neigh-
borhoods involved and some of their attendant limitations.
In general, neighborhoods only rarely coincide with tracts, minor civil
divisions, or other units for which data are published. The scheme for
neighborhood definition was designed this way to eliminate the possibility
of matching neighborhood records with published summary data for identified
geographic areas, thus resulting in disclosure of geographic information
which would tend to allow identification of individuals.
The neighborhoods were not designated with reference to maps. Neighbor-
hoods were formed by computer using geographic keys associated with each
1
S1-3
household record. The resulting neighborhoods are normally contiguous
and relatively compact and include an average of 4,000 to 5,000 people.
Socioeconomic or demographic data were not used in grouping units together
to form neighborhoods. Thus, it is quite possible that a neighborhood,
while being contiguous and compact may straddle a meaningful social boundary
such as an urban freeway. It is also possible that some neighborhoods will
consist of two noncontiguous clusters, though most often the separation
is minor, as in the combining of nonadjacent parts of two adjacent tracts.
Neighborhoods will not cross county lines except in the rare instances of
counties with extremely low population.
Neighborhoods on the tapes are not in any geographic order, and one neigh-
borhood will have no particular geographic relationship to those preceding
and succeeding it on the tape. For users desiring to increase sample size
by processing 15% sample data and 5% sample data together it may be noted
that neighborhoods occur in the same sequence in both files and, thus, the
average of 40 to 50 sample persons per neighborhood can be doubled. In
merging two files one should, however, note the possibility that a neigh-
borhood record present on a 5% file may not appear on the corresponding
15% file or vice versa if no households from that neighborhood happened
to be selected into that, latter public use sample. This will occur only
very rarely on 1-in-100 files, but can happen rather frequently on
1-in-1,000 and 1-in-10,000 subsamples. Even with 80 to 100 persons per
neighborhood in a 2-in-100 sample, the neighborhood units are still much
too small to be studied individually, and an aggregation of neighborhoods
according to the desired typology is necessary.
CONTROL COUNTS FOR ALL FILES
Any user of public use sample data should anticipate the possibility of
errors in his own processing, and should attempt to verify his tabulations
against other available tallies. Pages 10 thru 27 contain exact counts of
total persons, group quarters persons, occupied housing units and vacant
housing units selected into each public use sample within each identified
geographic area. A failure of user tallies to replicate these counts would
indicate an error in the user's data processing or an incorrectly copied
file.
More detailed tallies can be checked out using data in 1970 census printed
publications or summary tapes, but sampling variability must be taken into
account. Verification of public use sample tallies against published com-
plete count or full sample data is discussed in the DESCRIPTION AND TECH-
NICAL DOCUMENTATION, pages 189 to 193.

(3) The index of income concentration ranges from .01 to .99. As the index
approaches 1.0, the greater is the inequality of the income distribution.
A code of 00 indicates the index was suppressed due to unreliability. A
discussion of the index appears in PC(1)-C reports, page App-27. A paper
entitled "Index of Income Concentration in the 1970 Census" is available
on request.
(4) Poverty status is not determined for inmates of institutions, armed forces
living in military barracks, college students living in dormitories, or for
unrelated individuals less than 14 years old.

Supplement No. 2
Public Use Samples of Basic Records from the 1970 Census:
Description and Technical Documentation
This supplement discusses the sequence of person records within house-
hold, erroneous outlying area codes, and several typographic errors
found in previous documentation.
SEQUENCE OF PERSON RECORDS
Users may find it helpful that person records within each household
are sorted. There are two types of sequence depending on the presence
of subfamilies. If no subfamily is present the sequence is
Head of household
Wife of head (if present)
Other persons in the household, relatives or non-
relatives, in any sequence
If one or more subfamilies are present the sequence is
Head of household
Wife of head
Sons or daughters of the head, not in subfamily
Other relatives not in subfamily
Nonrelatives
Subfamily number 1: Head
Wife of head
Children
Subfamily number 2: Head
Wife of head
Children
- etc. -
CODES FOR OUTLYING AREAS
Pages 91-92 of the documentation indicate the codes for foreign countries
and outlying areas to be used with the following items: P15-16 - State
or Country of Birth, P71-72(15%) - Country of Birth of Parent, and
P77-78(15%) - State or Country of Residence 5 Years Ago. On two of
these items the codes for outlying areas appearing on public use sam-
ple tapes do not correspond to the documentation, due to a programming
error. The actual codes assigned to the outlying areas are shown below.
1
S2-2
P71-72(15%) P15-16 P77-78(15%)
Country of Birth State/Country State/Country of
Outlying Area of Parent* of Birth Residence 5 Years Ago
American Samoa 03 03 97
Canal Zone 04 07 97
Guam 05 14 97
Puerto Rico 06 43 97
Virgin Islands 07 52 97
Other U.S. possession 08 57 97
* This set of codes corresponds to what was originally documented for all
three items.
In P15-16 each outlying area can still be uniquely identified by differ-
entiating between U.S. possessions and foreign countries in P14, the
place of birth recode. For instance, a "43" in P15-16 represents Puerto
Rico if P14 contains "3" (outlying area) or Syria if P14 contains "4"
(foreign country). These U.S. possession codes do not conflict with any
U.S. State codes.
In P77-78(15%) the outlying areas have lost their identity by all being
assigned the code "97", which happens to also be the code for Trust
Territories of the Pacific (U.S. Administration). This group can, however,
still be distinguished from all other countries.
Correct tabulations of Countries of Residence 5 Years Ago for the full 15%
sample appear in the subject report PC(2)-2B: Mobility for States and the
Nation, table 55. Totals are given by State for four of the six outlying
areas. The U.S. figures are:
In Puerto Rico 5 Years Ago 142,831
In Canal Zone 5 Years Ago 17,927
In Guam 5 Years Ago 18,295
In Virgin Islands 5 Years Ago 3,280
Puerto Rico would be expected to account for most of the cases assigned
"97".
One additional note concerns Place of Birth (P14 and P15-16). The category
Born Abroad of American Parents, "2" in P14, "02" in P15-16, is not designed
to include all such persons. Most of these persons recorded their specific
country of birth and that their parents were born in the U.S. Thus, in
order to produce tabulations comparable to census tabulations for persons
born abroad of American parents, it is necessary to check the Nativity and
Parentage recode (P70(15%)) as well as Place of Birth (P14). In 5% data
samples the Citizenship item (P72(5%)) has a "born abroad of American
parents" category which is all-inclusive.

PUBLIC USE SAMPLES OF BASIC RECORDS FROM THE 1970 CENSUS:
DESCRIPTION AND TECHNICAL DOCUMENTATION
Supplements to the 1970 public use sample documentation are automatically
sent to persons or organizations who have purchased 1970 public use sample
tapes and/or documentation from the Bureau of the Census. Persons who have
distributed documentation to others are encouraged to reproduce copies of
supplements for their use. Users who have not purchased public use samples or
documentation directly from the Bureau of the Census may request single cop-
ies of specific supplements and be put on a list to automatically receive
future supplements, if any, by writing:
Users' Service Staff
Data User Services Division
Bureau of the Census
Washington, D.C 20233
This supplement contains information on certain data errors, typographical
errors in previous supplements, and the availability of three kinds of spe-
cial purpose public use samples; and announces a paper of interest to some
users.
CORRECTION TO NEIGHBORHOOD CHARACTERISTICS SAMPLES
Neighborhood Characteristics public use samples purchased prior to July 1973
contained erroneous Size of Urbanized Area codes in item H10. A correction
tape was sent to all who had purchased affected tapes from the Bureau of the
Census. The Bureau's master tapes have been corrected and all neighborhood
characteristics sample tapes sold since July 1973 have been corrected vers-
ions.
DATA ERRORS ON EXISTING PUBLIC USE SAMPLES
Several other errors, most of which affect relatively few records or are
unlikely to affect most research, have also been discovered on 1970 census
public use samples. One such error, concerning codes for outlying areas,
was reported in Supplement No. 2. Three additional types of errors are
discussed below.
As of this date, the Bureau is not planning to correct all of its master
public use sample tapes nor to issue correction tapes relative to these
errors. Users interested in studying any of the subjects affected by these
errors are encouraged to contact Paul Zeisset, Data Access and Use Labora-
tory, Bureau of the Census, Washington, D.C. 20233 (301/763-7454). Creation
of a new 1-in-1,000 sample with all known errors corrected is a possibility
provided sufficient interest is expressed by prospective users.
1
S3-2
P110, P111, P112 - INCOME ALLOCATION INDICATORS
All public use sample tapes contain erroneous income allocation flags in
items P110, P111, and P112, due to a programming error in the creation of
the tapes. The contents of these fields unfortunately bear no relation to
whether or not income of the various types in the individual record were
as reported by the respondent or were imputed (allocated) for nonresponse
or processing failure. Indication of allocation for Worked Last Year and
Weeks Worked in P110, and allocation for Employment Status Recode in P112
are not affected and may be presumed correct.
H77, H78, H79 - NUMBERS OF PERSONS OF SELECTED AGES
Items H77, H78, and H79 provide the number of related children under 18,
related children under 6, and persons 65 years old and over in the house-
hold, in a code range of 0 to 9 where 9 should indicate 9 or more such per-
sons in the household. In the existing public use samples households are
not correctly assigned to the upper limit "9" code when there are 10 or
more qualifying persons. Regardless of this error-it is always possible
to determine the correct number of household members in these categories
simply by tallying person records within a household directly. Item H76,
number of persons under 18 in household, and H80, number of persons 60+
in household excluding head, have the same 0 to 9 code structure, but are
correctly encoded. In fact H76 and H80 may be used to test the necessity
of retallying H77, H78 or H79 from person records since if H76 is less
than 9, H77 and H78 must be less than 9 and therefore not in error and if
H8O is less than 9, H79 may similarly be presumed correct.
P76 (15%), P77-78 (15%), AND P96 (15%) - RESIDENCE 5 YEARS AGO
The description for P76 (15%) category 6 now reads "State reported, place/
county not reported." To that should be added "or foreign country or out-
lying area with country not specified." Cases involving unspecified coun-
tries are relatively rare, but when they occur an erroneous State code
(06=California) appears in P77-78 (15%). Note that another problem with
these fields is documented in supplement No. 2.
In the 15% County Group Public Use Sample, P96 (15%) gives a slight under-
estimate of the metropolitan population 5 years ago. Clay County, Minnesota
(in the Fargo-Moorehead SMSA) was erroneously counted as nonmetropolitan.
This affects perhaps 100 cases in the entire 1-in-100 sample, and, outside
of county groups in Minnesota and North Dakota, one may assume the problem
is insignificant. This problem does not affect State or Neighborhood Char-
acteristics samples.

CHILDSPACING PUBLIC USE SAMPLE TO BE CREATED
A new one-in-a-hundred public use sample is being created in connection
with the subject report CHILDSPACING AND CURRENT FERTILITY, to be issued
in 1975. This public use sample will not cover the entire population,
but will contain data only for households with one or more females 14
years old or over (excluding those 55 years old or over who were first
married before 1950).
The unique feature of this sample will be the inclusion of a fertility
history record for each eligible female, containing sex and age in quar-
ters for all children ever born to the subject. This information goes
beyond that obtainable from other public use samples in that sex and age
are imputed for children born to the subject who are no longer in the
household and therefore not directly enumerated in the 1970 Census. Geo-
graphic identification is in terms of large States and groups of small
States, and residence in urbanized areas above or below one million pop-
ulation.
More information on the childspacing public use sample may be obtained by
writing Maurice J. Moore, Population Division, Bureau of the Census, Wash-
ington, D.C. 20233.
PUBLIC USE SAMPLE FILES FOR USER-DESIGNATED AREAS
Several users have obtained, on a cost-reimbursed basis, public use samples
identifying subdivisions of areas originally identified on the County Group
public use samples. These files may now be made available to other users
for the cost of reproduction. Files have been created for three SMSA's
separately identifying the central city from the remainder of the SMSA:
Buffalo, New York, Rochester, New York, and Detroit, Michigan. A file
for New York City subdivides the five boroughs into 27 large groups of
census tracts. In each case the requirement has been observed that every
area identified have at least 250,000 population.

A file for Cook County, Illinois has also been produced identifying 13
subdivisions of Chicago. Six months after job completion, or about April
1975, this file will also be available to other users for the cost of re-
production. Availability of this file and others created in the future
will be announced in Data User News (formerly Small-Area Data Notes).
Users interested in sponsoring similar public use samples for specially
designated areas should contact the Users' Service Staff. Of course ev-
ery designated area must have a population of at least 250,000. Costs for
the above-mentioned projects have been $2,500 to $5,000 for a one-in-one-
hundred sample of 15% data and a one-in-one-hundred sample of 5% data for
the area. These jobs have involved files in the same structure and format
as the original public use samples. Any change in format would increase
the cost and time required to do the job.
PUERTO RICO PUBLIC USE SAMPLE
As announced earlier in SMALL-AREA DATA NOTES, three public use samples of
basic records from the 1970 Census of Puerto Rico have been released. The
three samples corresponds in geographic identification to the State, County
Group and Neighborhood Characteristics public use samples issued for the
United States. The file structure is the same as on stateside samples, as
are most of the data items. However, some U.S. census items were not col-
lected in Puerto Rico (e.g., race, Spanish heritage), and they are replaced
on the Puerto Rico samples with items unique to that census (e.g., electric
lighting, land tenure). The Puerto Rico census did not have differentiated
15% and 5% versions of its long-form questionnaire; thus only three public
use samples were drawn, rather than six as for the U.S.
Each one-in-a-hundred sample consists of one reel of tape ($80). Documen-
tation, when purchased separately costs $3 and is avaailable from the Users'
Service Staff.
PAPER DESCRIBING ANNUAL DEMOGRAPHIC FILE
If you would be interested in a 1-in-1400 sample of the population avail-
able on an annual rather than a decennial basis, you should read a new
DATA ACCESS DESCRIPTION entitled "Microdata from the Current Population
Survey - the Annual Demographic File" (December, 1974). Subscribers to
SMALL-AREA DATA NOTES in 1974 will have received a copy. Others may re-
quest it from the Data Access and Use Laboratory, Data User Services Di-
vision, Bureau of the Census, Washington, D.C. 20233.
