Related Machine-Readable Files and Microfiche
Listed below are some of the 1980 census data files which have been or will be released.

Census of Population and housing, 1980: Summary Tape Files (STF's)
STF 1 provides 321 cells of complete-count population and housing data. Data are summarized for the United States, regions, divisions, States, SCSA's, SMSA's urbanized areas, congressional districts, counties, county subdivisions, places, census tracts, enumeration districts in unblocked areas, and blocks and block groups in blocked areas. This file set includes data shown in the PHC80-1, PHC80-3, and PC80-1-A reports. All State files have been released. Data from the STF 1A file are also available on microfiche.

STF 2 contains 2,292 cells of detailed complete-count population and housing data, of which 962 are repeated for race and/or Spanish origin groups present in the tabulation area. Data are summarized for the United States, regions, divisions, States, SCSA's, urbanized areas, counties, county subdivisions, places of 1,000 or more inhabitants, census tracts, American Indian reservations, and Alaska Native villages. This file set includes data shown in the PHC80-2, PC80-1-B, and HC80-1-A reports. Individual State files are being released as of February 1982.

STF 4 is the geographic counterpart of STF 2, but the number of cells of data is approximately three times greater. STF 4 provides detailed population and housing data estimated from the sample, some of which are repeated for race, Spanish origin, and ancestry groups. Data are summarized for areas similar to those shown for STF 2, except that data for places are limited to those with 2,500 or more inhabitants. This file set includes data shown in the PHC80-2, PC80-1-C, and HC80-1-8 reports. STF 4 is tentatively scheduled to be available from mid to late 1982.

STF 5 contains over 100,000 cells of population and housing data estimated from the sample and provides highly detailed tabulations and cross-classifications for States, SMSA's, and counties and cities of 50,000 or more inhabitants. Most subjects are classified by race and Spanish origin. This file set includes data shown in the PC80-1-D and HCeSO-2 reports. STF 5 is tentatively scheduled to be available from mid to late 1983.

Census of Population and Housing, 1980-Master Area Reference File (MARF)
An extract of STF 1A, this file contains numeric codes and names (where appropriate) of geographic areas plus selected complete-count population and housing data. All State files have been released.

Census of Population and Housing, 1980-P.L. 94-171 Population Counts
(Released February/March 1981).

The file, organized by State, provides counts for total population, and provisional counts for five racial categories and Spanish/Hispanic origin. Summaries are provided for the State, counties, minor civil divisions (MCD's) or census county divisions (CCD's), incorporated places or place segments witnin MCL)'s/CCD's, remainders of MCD's/CCD's, election precincts in certain States or portions of certain States, census tracts or block numbering areas, block: groups and blocks or, for areas that are not block numbered, enumeration districts (ED's). The figures presented in P.L. 94-171 may differ from those shown in STF 1. The changes reflect corrections of errors found after P.L. 94-171 was prepared. Microfiche (and paper photo copy of microfiche) of tne P.L. 94-171 Population Counts file is also available.

Metropolitan Map Series/Vicinity Map Series (MMS/VMS)
This map series provides coverage of densely settled areas of selected counties and county equivalents. These maps are referred to as the Metropolitan Map Series (MMS) when the maps cover SMSA areas and as the Vicinity Map Series (VMS) when the maps cover areas not in an SMSA. For a more detailed discussion of the MMS/VMS, see the section, "1980 Census Maps."

County Maps
The maps cover all counties and county equivalents except where the Metropolitan Map Series/Vicinity Map Series (MMS/VMS) sheets cover an entire county. Most county maps are based on maps supplied by State transportation or highway departments on which the Bureau has superimposed boundaries and identifiers for most areas for which data are tabulated. There are inserts to county maps for some counties that contain American Indian reservations. For a more detailed discussion on county maps and American Indian reservation maps, see the section, "1980 Census Maps."

Place Maps
Place maps are used for places not shown on MMS/VMS and show map features within the corporate limits of a municipality or within boundaries established for a census designated place (CDP). If census boundaries and identifiers for an area adjacent to a place are shown, the map is referred to as a place-and-vicinity map. For a more detailed discussion on place maps, see the section, "1980 Census Maps."

File Availability
STF 3A is arranged so that tapes for individual States or State equivalents can be purchased separately. Tapes are available at 1600 bpi or 6250 bpi, 9-track, at a cost of $140 per reel. If data for more than one State are stacked on a single reel at a customers request, the cost is $165 per reel. For information on the number of reels and release date for each State, subscribe to the Monthly Product Announcement (MPA). The MPA is available without charge and may be ordered using the Customer Services order form for publications.



STF 3B was originally part of the Census Bureau's 1980 program, but budget cutbacks forced cancellation of these plans. Since this cancellation, the Bureau signed a contract with National Planning Data Corporation (NPDC) of Ithaca, New York to prepare STF 3B as a special tabulation. During the first 18 months following the release of each State file, users may discuss purchasing the file from NPDC. After eighteen months, the Bureau will sell the file as a standard public use computer tape.



STF 3C is a national file which will be issued as a single file when STF 3A is completed.



STF 3 can be ordered using the Customer Services order form for tapes. When ordering from the Bureau, please refer to file number Cu SUM 80 010A for STF 3A, Cu SUM 80 010B for STF 3B, and Cu SUM 80 010C for STF 3C. Please indicate tne name of the State(s) when ordering STF 3A and STF 3B.

STF 3 File Description
Summary Tape File 3 (STF 3) is one of a series of summary data files available from the 1980 census. The file corresponds to the 1970 Fifth Count file and is composed of three parts - STF 3A, STF 3B, and STF 3C. File STF 3A is tentatively scheduled for release on a State-by-State basis in mid 1982. STF 3B will be released on a State-by-State basis first to National Planning Data Corporation (NPDC) which is funding the special tabulation. The file will be sold by NPDC for 18 months after which the file will be sold by the Census Bureau as a standard public use tape. STF 3C will be issued after all STF 3A and STF 3B files have been released.

File Structure and Geographic Coverage
For each geographic area there will be a 12,096-character census logical record. Because of its large record size, STF 3 is divided into six segments of 2,016 characters each with each. These segments are identified within the geographic identification section repeated for each segment.

The first segment of each census logical record begins with 252 characters of geographic information and the suppression flags, while each subsequent segment begins with 102 characters of geographic information.

The record segments were arranged so that individual tables do not cross segment boundaries. Because of this, most segments have some padding at the end. The following chart illustrates the segmentation on STF 3. For a concise description of the geographic coverage of each file in STF 3, see Appendix A.

STF 3 Segment Arrangement

Segment No. No. of Chars. (Geography) Tables No. of Chars. (Tables) No. of Chars. (Padding) Total Chars.
1 252 1-19 1,476 288 2,016

6 102 129-150 1,437 477 2,016
Total 762 1-150 10,489 846 12,096



File STF 3A
This file contains summary level data which follow a geographic hierarchy. In File A, block groups (BG's) or enumeration districts (ED's) are nested within a tract, block numbering area (BNA), or tract/BNA segment which in turn is sequenced within a place, place segment, remainder of MCD or remainder of CCD, then within a minor civil division (MCD) or census county division (CCD), and within a county or county equivalent. Data summaries are presented at each level. When a level of geography is split across the next higher level, only the portion within the higher level will be shown on the summary. For example, if tract 0001 is split between place 0005 and 0010, the summary for the portion in place 0005 will appear in the hierarchy with the place 0005 summaries while the portion in place 0010 will appear with the place 0010 summaries.

Place 0005
   Tract 0001 (part)
       :Block group 1
       :Block group 2
       Tract n
Place 0010
   Tract 0001 (part)
       Block group 3

In addition, place and congressional district summaries are presented separately from the hierarchically organized summaries. Each summary is identified by a summary level code in positions 10-11 of the record as well as at the beginning of each segment. Figure 1 outlines the specific geographic hierarchy in STF 3A. Each indentation indicates the next lower level of the geographic hierarchy. Following Figure 1 is a discussion of each summary level in the hierarchy.

Figure 1. Geographic Hierarchy of STF 3A



The State record (Summary Level 04) contains a summary for the State or State equivalent.

File STF 3D
This file contains summary level data which follow the geographic hierarchy indicated la figure 1 below. Records are shown for the State, a congressional district, then all counties within the congressional district. All county records are followed by records for all places of 10,000 or more within the congressional district and then by minor civil divisions (MCD's) with a population of 10,000 or more, in 11 selected States, within the congressional district. When a county, place, or MCD is split between two or more congressional districts, the summary record for a county, place, or MCD contained within each of the congressional districts geographic hierarchy will show only the data for that portion contained within the congressional district.

Figure 1 below outlines the geographic hierarchy. Following Figure 1 is a discussion of each summary level in the hierarchy.

Figure 1. Geographic Hierarchy of STF 3D



The State record (Summary Level 04) contains a summary for the State or State equivalent.

The Congressional District record (Summary Level 33) contains a summary for each congressional district within the State according to the congressional district boundaries established for the 98th Congress.

The County record (Summary Level 37) contains a record for each county or county equivalent, including independent cities, or portion of a county, county equivalent, or independent city located within each congressional district.

The Place record (Summary Level 38) contains a summary for each place with 10,000 or more inhabitants, as published in the 1980 census, or portion of a place, located within the congressional district.

The MCD record (Summary Level 39) contains a summary for each county subdivision (minor civil division) with 10,000 or more inhabitants, as published in the 1980 census, or portion of such an MOD, located within the congressional district for 11 selected States.

The county record (Summary Level 11) contains a summary for each county or county equivalent, including independent cities, within the State in FIPS code sequence.

The minor civil division (MCD)/census county division (CCD) record (Summary Level 12) contains a summary for each MCD/CCD within the county in census code sequence.

The place or remainder of MCD/CCD record (Summary Level 13) provides a summary for each place within an MCD/CCD in place code sequence. These may be places or, when places cross MCD/CCD boundaries, portions of places. A remainder of MCD/CCD record will be generated only if there is a place in the MCD/CCD. This record will cover all areas outside of places and will have a pseudo place code of 9999.

The combination of census tract/block numbering area (BNA) or untracted remainder of MCD/CCD (Summary Level 14), and block group (BG) (Summary Level 15) or enumeration district (ED) (Summary Level 16) summaries will vary according to the situation. The four situations are as follows:

Census tract or block numbering area (BNA)/block group (BG) - When a census tract or BNA is entirely block numbered, a summary is shown for each tract/BNA or tract/BNA portion within MCD/CCD and place; place segment, or remainder of MCD/CCD, and for each block group or block group segment within tract/BNA or tract/BNA portion.

Census tract/ED1 - When the area is tracted but contains no blocks, a summary is shown for each tract or tract portion within MCD/CCD and place, place segment, or remainder of MCD/CCD, and for each ED within tract.

Not Tracted/ED - When an area is not tracted or not within a BNA, a summary is shown for each ED within the MCD and place, place segment, or remainder of MCD/CCD. A pseudo-tract code of 999999 will appear in the tract code field.

Census tract/BG-ED1 - When a tract is partially block numbered, there will be a mixture of BG and ED summaries for the tract or the tract portion within MCD/CCD and place, place segment, or remainder of MCD/CCD. BG summaries will precede those for ED's in this situation.

The place total record (Summary Level 27) provides a summary for each place within the State. The place records are arranged by census place code.

The congressional district summary (Summary Level 33) contains summaries for each congressional district within the State arranged in numeric sequence. These are the congressional districts designated for the 96th Congress.

1When a tract, block numbering area, or block group crosses a place, MCD, or CCD boundary, there will be separate summaries for each portion within the higher-level entities. No totals for split tracts, BNA's, or block groups are provided.

File STF 3B
As with STF 3A, each logical record summary of STF 33 is identified by a summary level code in positions 10-11 of the first segment as well as at the beginning of each segment. When the level of geography is split across the next higher level, only the portion within the higher level of geography will be shown, (See example on STF 3A description above.) The geographic hierarchy for STF 3B appears in Figure 2.



STF 3B has records for each 5-digit ZIP code within a State in numeric order (Summary Level 35) followed by records for 5-digit ZIP codes within a State arranged in numeric order by SMSA or portion of SMSA, then county or county equivalent or \portion of county or county equivalent (Summary Level 36).

File STF 3C
This file is essentially a national file which will be issued only after STF's 3A and 38 have been released for all States. The geographic hierarchy for this file is shown in Figure 3 below.

Calculation of Medians in STF 3
Calculation of median values is done using a continuous distribution with the whole number as the mid-point of the class interval. However, if the median falls within the upper or lower interval, it is set to a specified value. Listed below in Figure 4 are the upper and lower intervals for each median in STF 3 and the median value set when it falls within that interval.

Suppression in STF 3
To maintain the confidentiality promised respondents and required by law, the Census Bureau takes precautions to make sure that its public data, in print or on tape, do not disclose information about particular individuals or housing units; therefore, the Bureau suppresses tabulations of characteristics for very small groups of people or housing units. On summary tapes, zeroes are entered in suppressed cells. Flag fields which indicate suppression are shown on each record. However, a zero in a cell does not automatically mean suppression. Only by checking the suppression flag can it be determined if the zero in a specific table is suppressed data or an actual count of zero.

This discussion outlines the rules for suppression of sample data, how its occurrence can be identified by the user, and how to handle it.

No Suppression
The following counts will never be suppressed:

  • Total population
  • Total housing units
  • Seasonal/migratory housing units
  • Year-round housing units
  • Occupied housing units
  • Vacant year-round housing units
  • Count of persons and households for each race or Spanish origin group


Primary Suppression
Suppression of Population Characteristics
Characteristics of persons other than race or Spanish origin (e.g., age, relationship) are shown only if there are 30 or more persons in the geographic area. For example, on a record for a census tract with a population of 1 to 29 persons, population characteristics such as age and relationship are suppressed. Only counts for total population and the number of persons within specific race or Spanish origin groups are provided.

However, when the geographic area being summarized has 30 or more persons, no suppression of population characteristics will occur except possibly when tables are further cross-classified by race or Spanish origin. The rules for this type of suppression are outlined below in Suppression of Tables Cross-Classified by Race or Spanish Origin.

Suppression of Year-round Housing Characteristics
Characteristics of year round housing units which are not classified by occupancy status (e.g., number of rooms, plumbing facilities, etc.) are suppressed only when there are fewer than ten year-round housing units in the geographic area being tabulated regardless of the number of occupied housing units or the number of persons.

Suppression of Family, Household, or Occupied Housing Characteristics
Characteristics of families, households, or occupied housing units are shown if there are at least ten occupied housing units within the geographic area tabulated.

Suppression of Owner or Renter Characteristics
Distributions of data for owners or renters are shown only when the number of owners is at least ten and the number of renters is also at least ten.

Suppression of Tables Cross-Classified by race or Spanish Origin
Population and housing characteristics cross-classified by race or Spanish origin are subject to an additional level of scrutiny. This level requires the 30 person or ten household criteria stated above of applied to each race or Spanish origin group.

Individual cells of data for specific race or Spanish origin groups are not suppressed when there are 30 or more persons of that group in a geographic area unless required by complementary suppression.

The population and housing suppression criteria are applied independently of one another. For example, if there are 32 White persons but only eight households with white householders, the person characteristics will be shown, but the family, household, and housing characteristics will be suppressed.

Complementary Suppression
In some cases complementary suppression is applied to prevent the derivation of suppressed data by subtraction. For instance, when a table shows the number of persons in unit for all households and also for renters, there must be at least ten owners and ten renters for the renter data to be shown; otherwise, the characteristics of the owners could be derived by subtracting renter data from data for all households.

Programming with Suppression
Suppressed data cells contain zeroes. To distinguish between zeroes as suppression and zeroes as valid data, occurrences of suppression are identified by a series of flag fields in the geographic identification portion of each logical record. Programmers developing software should include procedures to check these fields for the presence of suppression and, if necessary, to flag the output of any cumulation which includes one or more suppressed fields.

In reviewing the data dictionary, the programmer can determine which suppression flags indicate suppression for particular tables by checking either the table description or the flag description. An example of each follows.

Example: The boxed illustration on the following page is the table description as it appears in the data dictionary. The next portion illustrates the suppression flag to which the table description refers.



Figure 7 below, lists each suppression flag, its location within the record, and the tables or cells within tables which are affected when suppression is applied. The suppression flag field which applies to each table or portion of a table is also identified in the table description in the data dictionary. The flags are located in the geographic identification section of each record in positions 205236.

Evaluating the Effect of Suppression
In most cases, suppressed data values are small (fewer than 10 or 30) except where a large population is affected by complementary suppression. Therefore, in certain noncritical applications, users may simplify programming operations by ignoring suppression and treating suppressed cells as zero cells. However, when geographic entities are being summed to higher levels or new geographic areas are being created, suppression will usually result in a downward bias in the totals.

How to use the data dictionary
The data dictionary contains complete information regarding geographic codes, table information, and a detailed table layout. The following is an outline of information provided in both the geographic and table identification portions of the file.

Geographic Identification
The first line of each geographic identification variable gives the name, size/scale, begin position, relative begin position, and the variable label. Following those items, on subsequent lines, are any applicable notes and value codes. Each of these items is defined below.

This is an arbitrarily assigned a-character identifier. It may be a mnemonic such as "STATE" or
"EDNUMBER", or a sequential identifier such as "TAB1", "TAB2", etc.

Size/Scale
The size of a data item is given in characters.

This is the location in the data record of the first character of the data item.

Relative Begin
This value indicates the beginning location of a data item within a specified segment of files with segmented records.

Data Type
The data type (A) indicates that the data item is represented by an alphabetic code.

Description
Following the Data Type is a description of the data item. This heading is not labeled on the data dictionary. This section also provides any relevant notes or footnote references. In addition, any value codes necessary for the data item are listed and labeled here.

Table Identification
The documentation of tables begins, with the name, size/scale, begin position, relative begin position for the table, data type, and the number of cells. This information is followed by the table title, applicable suppression flags, universe definition, applicable footnotes, stratifier identification, and a listing of the cells.
These items are defined below.



Table Title
The title of the table identifies the stratifiers used in the table, and the number of categories in each stratifier. For example, this title indicates that there are five categories of race and four categories of school enrollment identified in the table.

Suppression Flags
This section of the documentation identifies applicable suppression flags and the cells to which they apply.

Universe
The universe identifies the unit of observation for the table. For example, the cells in this table are counts of persons 3 years old and over enrolled in school.

Footnotes
This section refers to footnotes listed at the end of the data dictionary which apply to the table.

Stratifiers
This section lists the stratifiers used in the table, in the order in which they appear on the data tape. For example, this table begins with the first category of race cross classified by the four school enrollment categories. This is followed by the four remaining categories of race, each of which is cross classified by the four categories of school enrollment. Headers representing stratifiers are followed by a colon and are not counted as cells.



Calculating the Location of Cells in STF 3
The location of the beginning character position for the first cell in each table is indicated in the "begin" column. The begin position for succeeding cells can be calculated by the following method.

(Begin Position of first cell) + [(Size of each cell) x (Number of previous cells in table)] = (Begin position f desired cell)

Example 1. Location of begin position for occupied housing units
