The Census 2000 Data Engine software is a customized version of SRC's Allocate product. Some of its basic functionality is illustrated below. Refer to the product's Help function for a complete overview of the software's functionality. A more detailed on-line tutorial is also available.

Installing and running the software requires being logged on as either an administrator or a power user if running Windows 2000 or Windows XP. The following procedure can be used to enable the software to be run while logged in as a regular user in these versions of Windows.

There are three setup files on the disc : one in the root directory which installs the software and one each in the DataSetupSF1 and DataSetupSF3 folders which install a separate data set.

[Back to Top]Installation

  • The Introductory Control Panel shown below is automatically displayed.
  • Click Install to load the software and perform the database setup. The database setup routine asks whether you want to do a Full Install or Run from Disc.

    • Run from Disc requires only about 9 MB. (Few users require the enhanced performance of Full Install.)
    • You need an internet browser for the off-line display/printing of reports and help pages.

[Back to Top]Using the file documentation as a reference

The 108th Congressional Districts file documentation is contained in files named cd108h.pdf and cd108s.pdf, for the SF1 and SF3 based data sets respectively, on the disc. The following are some suggested uses of these files for reference.

Chapter 4 Summary Level Sequence Chart can be used to find complete descriptions of area types (for which summary data is available) that you can select from the Pick Geography tab. Codes for each element making up the complete summary level description will appear as part of a field labeled KEY in output files created by the software. These codes can also be outputted to separate fields in output files by selecting the Simple Variables tab and then clicking on the + sign to the left of Geographic Identifiers.

Chapter 7 Data Dictionary Identification Section contains descriptions of all of the geographic identifiers. Appendix A contains definitions of all geographic terms.

Chapter 3 Subject Locator can be used as an aid in finding tables that appear in the Simple Variables tab. This chapter is also useful in making sure tables which may be of interest are not overlooked. The Table Matrix section of Chapter 7 Data Dictionary can be used to see a complete description of a table, including additional headings (such as the Universe) as well as all of the data items.
