The number of individuals per unit area

• Populaiton decrease

• population increase

• population explosion

• population density

The average number of years a person is expected to live

• life expectancy

• infant mortality rate

• fertility rate

• literacy rate

The rate at which babies under 1-years-old die per 1000 born

• life expectancy

• literacy rate

• infant mortality rate

• fertility rate

Shows what fraction of a starting group is still alive at each successive age

• Age structure diagram

• population pyramid

• survivorship curve

• life expectacny

curves usually have small numbers of offspring and provide lots of parental care to make sure those offspring survive

• type 1

• type 2

• type 3

• type 4

may also have relatively few offspring and provide significant parental care with mortality rates consistent throughout lifespan

• type 1 survivorship

• type 2 survivship

• type 3 survivorship

• type 4 survivorship

usually have lots of offspring at once—such as a tree releasing thousands of seeds—but don't provide much care for the offspring, typically die early in life

• type 1 survivorship

• type 2 survivorship

• type 3 survivorship

• type 4 survivorship
