2. How were the data generated, processed, and modified?

   Date: Apr-2002 (process 1 of 2)

   All the census data sets were loaded into ArcView and joined into a single database file using the FIPS-code field. Fields for county name, State name abbreviation, State FIPS, and ratio of males to females were added. The final database was called ce2000t.dbf.

   Data sources used in this process:

   • CEN2000_1
   • CEN2000_2
   • CEN2000_3
   • CEN2000_4
   • CEN2000_5
   • CEN2000_6
   • CEN2000_7
   • CEN2000_8
   • CEN2000_9
   • CEN2000_10
   • CEN2000_11
   • CEN2000_12
   • CEN2000_13
   • CEN2000_14
   • CEN2000_15
   • CEN2000_16

   Data sources produced in this process:

   • ATLAS-CE2000

   Date: Jun-2004 (process 2 of 2)

   Fields containing data for population change between 1990 and 2000, median age in 2000, and age over 65 for 2000 were extracted from DATABOOK. The percent of the population over 65 was computed. The resulting database containing the three new fields of data was appended to ATLAS_CE2000.

   Data sources used in this process:

   • DATABOOK
   • ATLAS-CE2000

3. What similar or related data should the user be aware of?
