USER NOTES:

A ZIP Code tabulation area (ZCTA) is a statistical geographic entity that 
approximates the delivery area for a U.S. Postal Service five-digit or three-digit 
ZIP Code. ZCTAs are aggregations of census blocks that have the same predominant ZIP
Code associated with the residential mailing addresses in the U.S. Census Bureaus 
Master Address File. Three-digit ZCTA codes are applied to large contiguous areas 
for which the U.S. Census Bureau does not have five-digit ZIP Code information in 
its Master Address File. ZCTAs do not precisely depict ZIP Code delivery areas, and 
do not include all ZIP Codes used for mail delivery. The U.S. Census Bureau has 
established ZCTAs as a new geographic entity similar to, but replacing, data 
tabulations for ZIP Codes undertaken in conjunction with the 1990 and earlier 
censuses.

A note concerning data scale:

Scale is an important factor in data usage. Certain scale datasets are not
suitable for some project, analysis, or modelling purposes. Please be sure
you are using the best available data.

1:24000 scale datasets are recommended for projects that are at the county
level. 1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.

1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.

1:250000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be considered
suspect. Make sure you are familiar with your data before using it for
projects or analyses. Every effort has been made to supply the user with
data documentation. For additional information, see the References section
and the Data Source Contact section of this documentation. For more
information regarding scale and accuracy, see our web pages at:

DATA LINEAGE SUMMARY:

Data was originally released by US Census Bureau in 2000. Data was downloaded by 
GeoPlan in shapefile format from ESRI 
(http://www.esri.com/data/download/census2000_tigerline/index.html).
When received, data was in Geographic projection, Datum: NAD83, Spheroid: GRS1980, Units: Decimal degrees.  The data was then projected to FGDL Albers HPGN 
(See "Map Projection Parameters" below).
