| Readme File for HC012 Data
Below are technical specifications and programming information for the HC012
data file. Users are strongly encouraged to read the documentation file
(HC012DOC.PDF or HC012DOC.HTM) provided in this release for additional
information on the content of this file.
HC012.DAT: This file contains the HC012 data in ASCII format. It
contains 22,601 records with 1280 variables. This file has a logical record
length of 3565 with an additional 2-byte carriage return/line feed at
the end of each record.
HC012.SSP: This file contains the HC012 data in SAS Transport
format. See the HC012SU.TXT file for information applicable to SAS users of
the HC012 data.
Note: For users' convenience, both of these data files (i.e., the ASCII data
files and the SAS Transport data files) are provided in two compressed
formats: 1) a compressed ZIP file and 2) a self-extracting executable file.
See Notes on Viewing and Downloading Files for information on uncompressing
HC012SU.TXT: This ASCII file contains information for
SAS users of the HC012 data. This includes information on the SAS Transport
version of the HC012 data, as well as SAS statements for converting
the ASCII data file into a SAS data set (in lieu of using the SAS Transport
file) and for creating and using SAS formats. This file also includes
helpful information for inexperienced SAS users, such as sample SAS program
HC012SPU.TXT: This ASCII file contains information for SPSS users of the
HC012 data, including statements for use in converting the ASCII data file
(HC012.DAT) into an SPSS data set.
HC012CB.PDF: This PDF file contains the codebook for the HC012 data
file. It indicates the record layout (i.e., the start and end position of
each variable) of the file. The codebook also includes listings of the
variables in both alphabetical and position order, as well as the following
information for each variable: 8 character name, 40 character description,
format (length), type (character or numeric), start and end positions, and
unweighted and weighted frequencies.
The codebook is also available as an active page HC012CB.ASP and an HTML
page. The active page allows users to link directly to the frequencies
portion of the codebook from the listing of variables section.
