population density - infographic

POPULATION DENSITY

how close people are; how many people are relying on something

population statistc

arithmetic

physiological

agricultural

the number of people per unit of land

the number of people per unit of arable land

the number of farmers per unit of arable land

• measurement of land productivity
• shows relation to CARRY CAPACITY

• measurement of farmer productivity
• shows TECHNOLOGY

• general measurement of density
• shows how close people LIVE together

Population density, in its various forms, is capable of telling multiple characteristcs about the present population, how it will change, and how people live on a day-to-day basis.

Present Day

Future

the people today are clustered around where they can best be supplied

cities, however, are areas of very high density and also very high productivity

people continue to migrate to cities and increase their densities in the LDCs; these areas are expected to see growth, but also challenges

areas with less arable land have more imports of food, showing the effectiveness of the global network

high population densities have health issues if not managed correctly

larger populations, bigger cities, more farming chemicals all threaten the carrying capacity of the Earth; population density can be a measurement for us to gauge how we need to change to be more sustainable

less developed countries have less technology and weaker economies because they have high agricultural densities; their population works on the farms

a common trend in the US is movement to the suburbs, areas that have lower densities
