        are characters 11-15 of the HDR2, EOV2 and EOF2 records.

        record on the tapes consists of fifteen 120-character logical records.

        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.

   After the publication of the documentation, it became necessary to revise                                               
   the production plan for the samples and to derive neighborhood character-

   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

   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

   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

   (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

   unlikely to affect most research, have also been discovered on 1970 census

   was reported in Supplement No. 2. Three additional types of errors are                                                  
   discussed below.

   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.

   The description for P76 (15%) category 6 now reads "State reported, place/

   (06=California) appears in P77-78 (15%). Note that another problem with

   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

   basic records from the 1970 Census of Puerto Rico have been released. The                                               
   three samples corresponds in geographic identification to the State, County
