How do we determine population density?

In the U.S. population density is typically expressed as the number of people per square mile of land area. The U.S. value is calculated by dividing the total U.S. population (316 million in 2013) by the total U.S. land area (3.5 million square miles).

Density-dependent factors include disease competition and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship these limiting factors increase with the size of the population and limit growth as population size increases.

What are the characteristics of population density?

Population density just gives the average number of individuals per unit of area or volume. Often individuals in a population are not spread out evenly.
