What is the definition of birth rate?

• The number of live births per 1,000,000 people per year

• The number of live births per 1000 people per year

• The number of infants who survive to 5 years old per year

• The number of infant deaths per year

What is the definition of death rate?

• the number of deaths per 1000 people per year

• the average span of of years someone lives

• the number of deaths per 1,000,000 per year

• the number of live babies born for every 1000 people

What is the definition of life expectancy?

• the average number of live births per 1000 people

• the expected average life span of a particular population

• the average number of deaths per 1000 people

• the expected number of infant deaths per 1000 live births

What is the definition of natural increase?

• the rate of population growth calculated by subtracting the death rate from the birth rate

• the rate of population growth calculated by averaging birth rates

• the rate of population growth calculated by averaging death rates

• the rate of population growth calculated by averaging infant mortality rates

What three things are most important when calculating the population change of a particular place?

• birth rate, infant mortality, medical care

• migration, life expectancy, infant mortality

• birth rate, death rate, migration

What does a population pyramid show

• the number of females and males divided into age groups of a particular area; shows life expectancy

• the average number of life births to stillbirths

• the number of people who survive after the age of five; does not show life expectancy

• the death rate of children under the age of five

the number of individuals per unit area

• density

• dispersion

• growth rate

• population

What is over-population?

• Pressure on natural resources due to too many people

• Not enough people to exploit the natural resources

• When birth rate plus immigration exceeds death rate

• When birth rate is over 60 per 1000 people
