The total number of people divided by the total land area

The percentage growth of a population (birth rate-death rate)

Very high CBR and CDR; very low NIR

Shows stages of demographic changes of birth/death rates within a country

The average number of years an individual is expected to live in a place

The ratio of the number of farmers to the total amount of arable land

When the number of people exceeds the carrying capacity of a place

Very low CBR, low/slightly increasing CDR, and zero/declining NIR

Rapidly declining CBR, moderately declining CDR, and moderate NIR

Graph that shows that as population grows exponentially, resource use will grow exponentially
