3.  **About the FTP Application**

    -   The application is intended for experienced users of census
        data, compressed files, and spreadsheet/database software.

    -   FTP users should have a fast file transfer capability.

    -   Users of the FTP application need to unzip the compressed file
        after downloading, then import it into the spreadsheet/database
        software of their choice for data analysis and table
        presentation.

    **Other Sources of the Data**

    -   [American FactFinder](http://factfinder.census.gov/) at
        factfinder.census.gov .

■ This system provides Internet access to all tables plus additional
derived tables called Quick Tables and Geographic Comparison Tables.

-   The system can create thematic maps on various data items.

```{=html}
<!-- -->
```
-   The system can create reference maps defining the geographic area.

-   Tables are available on American FactFinder on the morning of public
    release.

```{=html}
<!-- -->
```
-   DVD/CD-ROM

■ Data for the State Legislative Districts also will be available on DVD
shortly after the public release date.

-   The discs will contain easy-to-use software enabling users to
    download tabulations from the files.

-   We expect the State Legislative District data to fit on one DVD. For
    ordering information, contact the Customer Services Center at
    301-763-INFO (4636) or send an email to <webmaster@census.gov>.
    Business hours are 8:30 AM -- 4:30 PM EST, Monday through Friday.

5.  **File Naming Conventions**

    -   The naming convention for geographic header files is
        *ssgeo*\_sl3.zip

        -   *ss* is USPS state abbreviation

            1.  ■ The codes are in technical documentation on page 7-1,
                located at
                <http://www.census.gov/prod/cen2000/doc/slds.pdf>

        -   *geo*\_sl3.zip is a constant across SLD geographic header
            names.

    -   Naming convention for SLD data files is *ssiiiyy*\_sl3.zip.

        -   *ss* is USPS state abbreviation

        -   *iii* is the characteristic iteration (total population,
            race groups, American Indian and Alaska Native tribes, and
            Hispanic/Latino groups). These only apply to SF 2 and SF 4.
            In SLD, the characteristic iteration will always be 000.

        -   *yy* is the number of the file

            1.  ■ Valid codes are 01 through 76. See below for
                distribution of tables across files.

            -   \_sl3.zip is a constant across SLD Sample data file
                names

####### Technical Documentation

-   The complete technical documentation for State Legislative Districts
    -- Sample is available at
    <http://www.census.gov/prod/cen2000/doc/slds.pdf> .

**Data Records and Segmentation**

-   Five fields are carried over from the geographic header file into
    each data file.

    -   These fields are file identification (FILEID), state
        abbreviation (STUSAB), characteristic iteration (CHARITER),
        characteristic iteration file sequence number (CIFSN) and
        logical record number (LOGRECNO).

■ These five fields appear in the *geographic header* file in a fixed
field format.

-   These five fields appear in the *76* *data* files in a comma
    delimited format.

-   These fields are used to "match" records in the *76 data* files to
    the geographic information in the geoheader.

-   A file set structure schematic appears in the technical
    documentation which is located at

> <http://www.census.gov/prod/cen2000/doc/slds.pdf>

6.  **File Record Layout**

■ For a layout of the individual tables for each file, see the technical
documentation at <http://www.census.gov/prod/cen2000/doc/slds.pdf> .
Select Chapter 6, *Summary Table Outlines.*

# FTP File Transfer

-   State Legislative District -- Sample FTP directory is at

-   Downloading multiple files

    -   UNIX environment---"mget" subcommand allows transfer of multiple
        files using the wildcard character.

> ftp\>mget ne\* (for this example, Nebraska is selected).

-   Windows Environment---many FTP products have been developed which
    have the capability to download multiple files with a single

####### Unzipping the Files 

-   Files compress at approximately 95% compression.

-   Any standard UnZIP software package can be used.

    -   In testing we used PKZIP for Windows. It's available at
        [www.pkware.com](http://www.pkware.com/). .

-   Unzipped files are in flat ASCII format.
