Metadata
What follows is very detailed technical information about this data table. This is often
called metadata. Metadata (or "data about data") describe the content, quality,
condition, and other characteristics of data. Metadata are used to organize and maintain
investments in data, to provide information to data catalogs and clearinghouses, and to
aid data transfers. The Federal Geographic Data Committee
(FGDC) publishes the Content Standard
for Digital Geospatial Metadata. Many organizations within and outside of the federal
government have adopted the FGDC metadata standard and are using automated indexing and
serving mechanisms to provide access to their holdings through the Internet. Visit the FGDC Clearinghouse to
learn more about how metadata is used in clearinghouses and to search for other data sets.

- Description:
- Abstract:
- This data set includes U.S. Census Bureau population information for the United States,
presented by county. Included are total population counts, various statistics on ethnic
and gender distributions, and income statistics.
- Purpose:
- The digital data sets are used to create electronic and hard copy maps that depict
various aspects of the nation. The data can be used to conduct geographic analysis on
National and large regional scales. The digital data will provide a basis from which
future revisions of the atlas can be derived.
- Supplemental_Information:
- In the online, interactive National Atlas of the United States, this file is linked to
the 1990 County Boundaries file (co1990p020) for display purposes.

- Process_Step:
- Process_Description:
- CEN1 ane CEN2 were loaded into ArcView and joined using the Areaname field. The result
was exported to a new table. CEN4 was used to calculate the number of square miles in each
FIPS area, and the resulting Square_mil field was added to the new table created from CEN1
and CEN2. Some field names in the table were modified and the result was exported to CEN5.
In CEN5, a 5-digit FIPS field was created from the original 7-digit Stcou field, and
fields were added for population per square mile, the ratio of males to females, and group
population as a percentage of total population. In addition, the State FIPS code field was
changed from 5-digit to 2- digit, for compatibility with other files. The fields for 1980
data were turned off, and the results were exported to ce1990t.dbf.
