The entries under the Area in square miles headings are areas.
The entries under the Population and Housing Units headings are totals.
The Density per square mile of land area values are derived by dividing the population (or housing unit) count by the land ares. For example, dividing the total US population of 281,421,906 by the total land area of 3,537,438.44 gives a density value of 79.6 people per square mile.
In this chart the length of all of the colored bars represent percentages of the highest value of any county in the state. For example, the county with the highest population will have a colored bar that fills the cell. A county with half that many people will have a colored bar that fills half the cell. The same method is used for the colored bars shown in the Area and Density table cells. For small percentages the bar does not appear.
Abbreviations used in location names: Co.=County, C.A.=Census Area, Pa.=Parish, Mu.=Municipio.
