There are 25 elephants in a reserve that is 10 miles by 5 miles. what is the population density?

explanation:

to calculate the population density, you will divide the population by the size of the area. thus, population density = number of people/land area. the unit of land area should be square miles or square kilometers. you can use square feet or meters if you are finding the density of a smallish space.

learn the formula. to calculate the population density, you will divide the population by the size of the area. thus, population density = number of people/land area.

the unit of land area should be square miles or square kilometers. you can use square feet or meters if you are finding the density of a smallish space. for most professional and academic demographic purposes, though, you'll need to use the standard square miles or kilometers.

the unit of population density is people per unit of area. for instance, 2000 people per square mile.

plug your data into the formula. you should know the population and the surface area of the region. for example: if there are 145,000 people in the city of auburn, and the urban area covers 9 square miles, write 145,000/9 square miles.

divide the population by the area size. use long division, or just use a calculator. in our example, 145,000 divided by 9 would show that the population density is 16,111 people/square mile.

compare population density. compare data from multiple areas, and use the contrasting population densities to make observations about those areas. for example: if the city of boonesville includes 60,000 people overs its 8 square miles, then its population density is 7,500/square mile. you can see that the population density of auburn is far higher than the population density of boonesville. consider whether you can use this difference to draw any conclusions about the two cities.[5]

even if you calculate the population density of an area as dense as a large city, the resulting figure will not tell you much about the differences between individual neighborhoods. you may need to find the density for various area scales in order to fully understand a place.

Bacteria. These one-cell organisms are responsible for illnesses such as strep throat, urinary tract infections and tuberculosis. Viruses. Even smaller than bacteria, viruses cause a multitude of diseases ranging from the common cold to AIDS. (Here is some that I found.)
