                       Population Density

Explanation of Indicator
This indicator describes the average number of people occupying one square mile in Florida. Since
increases in population tend to be directly related to increases in environmental degradation, absolute
levels of population density and the rate of change in population density provide a graphic view of the
effect of population growth on environmental quality. The total land area of Florida is 54,153 square
miles. The population density is derived by dividing total square miles into the total population.


Source
This information is found in the Florida Statistical Abstract, produced annually by the Bureau of
Economic and Business Research, College of Business Administration, University of Florida, Gainesville,
Florida 32611-2017, or (904) 392-0171. The abstract is available at most major libraries. It may also be
purchased from University Press of Florida, 15 N.W. 15th Street, Gainesville, Florida 32611, or (904)
392-1351.


Data Characteristics
This information is collected annually, statewide by county. There are no costs associated with obtaining
the data from a public or university library, however the Abstract costs $19.95 to purchase.


Overall Assessment
This is a good indicator since population growth can indirectly indicate the stress placed on the
environment. While the indicator displays roughly the same information as does straight population,
showing population growth as a ratio of a fixed commodity like land makes the impact more graphic and
meaningful. These figures are estimates derived from mathematical analyses, not actual counts.


Analysis of Indicator
Increases in population density mirror the increases in absolute population. From 1830 to 1990 the
population density has increased 371.3 times, from .641 to 238.914 persons per square mile. This trend
has continued in the 90s, with each year seeing an increase in population density. The density has more
than quadrupled from 1950 to 1990. The greatest percent of change in Florida's population density
occurred between 1950 and 1960, when the density increased by 40.261 persons per square mile, or
78.7 percent. The smallest amount of change in a decade occurred between 1910 and 1920, when the
absolute change was only 3.986, or 28.7 percent.
