How do you determine a populations growth rate?

How do you determine a populations growth rate? Count the number of people that were

born, died emigrated and immigrated and compare that to

the number of people which existed the previous year.

Determine the population growth rate if there were 20,000 people living on

Catalina in 2012 and in 2013 100 babies were born, 50 people died, 5

people immigrated to the island and 3 people emigrated from the island.

1. 100 births+ 5immigrants – 50deaths -3emigres = an increase of 52 people

2. 52 people/20,000 people = 0.25% growth rate

If Catalina has a 0.25% growth rate, how many years will it take the

population to double?

If Catalina has a 0.25% growth rate, how many years will it take the

population to double?

Use the rule of 70:

70/0.25 = 280 YEARS

Define the following: Crude Birth Rate, Crude Death Rate, the Total

Fertility Rate and Replacement Level Fertility

CBR =

CDR =

TFR =

RLF =

Define the following: Crude Birth Rate, Crude Death Rate, the Total

Fertility Rate and Replacement Level Fertility

CBR = Number of births per 1000 people

CDR = Number of deaths per 1000 people

TFR = Average number of children each woman will have

RLF = Number of children each couple must have to prevent the population from declining. (2.1 in U.S.)

Calculate the population growth rate of the world if the CDR is 8

and the CBR is 20.

Calculate the population growth rate of the world if the CDR is 8

and the CBR is 20.

World population growth rate = (CBR-CDR) divided by 10

Divide by 10 because CBR and CDR are per 1000 people.

(20-8) divided by 10 = 1.2 percent.

If the world’s human population is growing at a 1.2% rate, how long

will it take for the world’s population to double?

If the world’s human population is growing at a 1.2% rate, how long

will it take for the world’s population to double?

Use the Rule of 70 to calculate doubling time.

70/1.2 = 58 years

Look at the age structures below and determine which population is

growing the fastest and which is declining the fastest.

Look at the age structures below and determine which population is

growing the fastest and which is declining the fastest. Nigeria is

growing the fastest and Bulgaria is declining the fastest.

Know the factors that influence growth rates of developing and

developed countries.

Know the factors that influence growth rates of developing and

developed countries. Developed Countries

Good nutrition/potable water

Good health care

High GDP per capita

High Literacy Rates

High value placed on women

Education is important

Having many children to work the land or take care of elders is not considered important.

Developing Countries

Poor nutrition/non potable water

Poor health care

Low GDP per capita

Low Literacy Rates

Low value placed on women

Low value placed on education

Children are important sources of income and take care of elders.

Urban Areas = _____% of the worlds population.

Urban Areas consume _______% of the world’s resources.

Urban Areas = __50___% of the worlds population.

Urban Areas consume __75_____% of the world’s resources.

mortality rate

What are the 3 layers of the earth, which layer is the hottest, and why is

that layer so hot?

What are the 3 layers of the earth, which layer is the hottest, and why is

that layer so hot?

Core is the hottest because it has the most radioactive decay.
