Key Definitions• Population: total number of people
• Population Distribution: general pattern of where people live
• Population Density: total number of people per …
– Arithmetic density: square mile or km of land
– Physiologic density: square mile or km of arable (farmable) land

Arithmetic Density
People per square mi or km
![Page 16: Population Density and Distribution](https://reader034.fdocuments.net/reader034/viewer/2022052620/55744d5ad8b42a0c468b46fd/html5/thumbnails/16.jpg)
Physiologic Density
People per sq mi or km of arable (farmable) land
How are these patterns different from those on the arithmetic density map?

Why Is Physiologic Density Important?
Carrying capacity!Egypt: 98% of the people live on 3% of
the land
