| Readme File for H51B Data
Below are technical specifications and programming information for the H51B
data file. Users are strongly encouraged to read the documentation file
(H51BDOC.PDF or H51BDOC.HTM) provided in this release for additional
information on the content of this file.
H51B.DAT: This file contains the H51B data in ASCII format. It
contains 22,582 records with 74 variables. This file has a logical record
length of 305 with an additional 2-byte carriage return/line feed at
the end of each record.
H51B.SSP: This file contains the H51B data in SAS Transport
format. See the H51BSU.TXT file for information applicable to SAS users of
the H51B 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
H51BSU.TXT: This ASCII file contains information for
SAS users of the H51B data. This includes information on the SAS Transport
version of the H51B 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
H51BSPU.TXT: This ASCII file contains information for SPSS users of the
H51B data, including statements for use in converting the ASCII data file
(H51B.DAT) into an SPSS data set.
H51BCB.PDF: This PDF file contains the codebook for the H51B 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 H51BCB.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.
