Birthrate- number of live births per 1000
people Ex. 54/100 in Niger, 8/1000 in Latvia, 22/1000
in world Fertility rate- average number of children a
woman of childbearing years would have in her lifetime if she had them at the current rate for her country 2.1 replaces population, 3.0 is average in world
Death rate- aka mortality rate, number of deaths per 1000 Low rate means a healthy population

Infant mortality: the number of deaths
among infants under the age of 1 per 1000 live births high IM rate usually means poor
healthcare Rate of natural increase: population
growth rate Mortality rate – Birth rate = Rate of
natural increase Population pyramid: device showing
sex and age distribution of a population

Population Pyramid
• The PYRAMID on the left shows rapid growth
• The BOX shaped one in the middle shows slow growth
• The CUP shaped one on the right shows negative growth

Population density: # of people/mi2 or # of
people/km2 Low density examples: Alaska 1 people/mi2,
Mongolia 6 people/mi2
High density examples: New Jersey 1,098 ppl/mi2, Singapore 16,714 ppl/mi2
Carrying capacity: number of organisms a piece of land can support based on resources, space etc.
