Components of Change information is derived from the following table.

Table 1.72. COMPONENTS OF CHANGE: COMPONENTS OF 
POPULATION CHANGE IN THE COUNTIES OF FLORIDA, 
APRIL 1, 2000 TO APRIL 1, 2003

Note: 1/ Natural increase is calculated as the difference between 
the number of births and the number of deaths; net migration is calculated 
as the difference between total population change and natural increase.
Vital statistics data for persons of unreported residence are included only 
in the entries for the state. For this reason, natural increase and net 
migration columns may not add to their state totals. 
Census data has been revised.

Projections information is derived from the following table.

Table 1.41. PROJECTIONS: ESTIMATES, APRIL 1, 2003, AND 
PROJECTIONS SPECIFIED YEARS APRIL 1, 2010 THROUGH 2030, 
IN THE COUNTIES OF FLORIDA

Note: The medium projection is the one we believe is most likely to 
provide an accurate forecast of future population. The high and low 
projections indicate the range in which future populations are likely
to fall. They do not represent absolute limits to growth; for any county, 
the future population may be above the high projection or below  the 
low projection. If future distributions of errors are similar to past 
distributions, however, future populations will fall between high and 
low projections in approximately two-thirds of Florida's counties. For a 
detailed description of projection methodology, see the source.

County Density information is derived from the following table.

ESTIMATES, RANK PERCENTAGE DISTRIBUTION, LAND AREA,

Note:  (X) Not applicable.

and are not adjusted for lands which cannot be developed 
(government-owned parks or reserves) or are uninhabitable 
(swamps or marshes).

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling 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.
1:125000 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 analysis. 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 webpage at:

DATA LINEAGE SUMMARY: 








This data layer was originally created by the US Census Bureau. 
The GeoPlan Center acquired this dataset from the Florida Department 
of Environmental Protection GIS Division. This dataset was previously 
released in FGDL Version 3 (released July 2000), and there was an 
error in the eastern border of Polk County/ western border of Osceola. 
The border has been corrected and updated for this new version of the 
dataset.
Process Date: 20000000


The county boundaries data layer was acquired from the 
Florida Department of Environmental Protection GIS Division.
Process Date: 20010000


Corrected Sumter/Hernando border and Polk county boundary.
Process Date: 20040900


The County boundary TIGER/Line file (cntbnd.shp) was enhanced at
the Geoplan Center by the addition/standardization of 
attribute data from the two United States Census Bureau sources. 

GeoPlan, during the QA/QC process included the following aspects:

-Reprojected data to FGDL Albers HPGN
-Removed the [OBJECTID], [AREA], [PERIMETER], [FGDLCODE], [AUTOID], 
[SHAPE_AREA], and [SHAPE_LEN] fields from the attribute table.  
The field [FIPS] was then renamed [FIRST_FIPS].  
GeoPlan then added the following fields:  [1830], [1840], [1850], [1860], 
[1870], [1880], [1890], [1900], [1910], [1920], [1930], [1940], [1950], 
[1960], [1970], [1980], [1990], [2000].  
These fields were then populated with the historical population 
data for each county.  
Present day Bradford County was assigned the 1860 population 
data originally assigned to New River County.  Also, present day 
Brevard County was assigned the 1850 population data originally 
assigned to St. Lucie County.  
Additionally, the 1830 population data originally assigned to Santa Rosa 
County was assigned to present day Santa Rosa County, 
although present day Santa Rosa County was created in 1842.
Process Date: 20061027


The County boundary TIGER/Line file (cntbnd.shp) was enhanced at
the Geoplan Center by the addition/standardization of 
attribute data from the 2004 Florida Statistical Abstract Population profile. 
The population projection attribute data was acquired from 
the Bureau of Economic and Business Research (BEBR):

http://www.bebr.ufl.edu

GeoPlan, during the QA/QC process included the following aspects:

-Extracted population projection attribute data from the 
2004 Florida Statistical Abstract Population profile. 
The attribute data was then linked to TIGER/Line County boundary file.
-Added a DESCRIPT field based on NAME (County name).
-Added FGDLAQDATE based on the date FGDL acquired the BEBR data.
Process Date: 20061027
