DDA converts all raw data into a dBASE structure before further processing is possible.

 

This section is focused on processing the Census 2010 Summary File 1 (SF1) data, as downloaded from the Census Bureau, into the dBASE structure used by DDA.

 

The steps to convert state SF1 files to dBASE are summarized below.

 

1. Get the State SF1 raw data (SF1 data are packaged by state by the Census Bureau in a zip file).

 

Use File>Get SF1 to download the state SF1 zip file to your computer.

 

2. Unzip the required SF1 data segments (unzip the downloaded SF1 zip file).

 

Use File>Zip/Unzip to unzip the needed segments.

 

3. Use Tools>Create Census 2010 SF1 DBFs

 

Processing starts.

 

All segments are generated for all segments expanded from the Census-sourced zip file.  That is, if only the geographic segment (required) and segments 1, 2 and 3 are found in the designated folder, dbfs will be generated for only those segments.
