Homework: Chapter 2, Key Issue 3 (Due 8/29) Agenda: Homework: Chapter 2, Key Issue 3 (Due 8/29) Notes: Population Growth Test Corrections Due 8/29 Open: Conference and Lunch
Objective: You will be able to describe how geographers analyze population change in writing.
Fun Fact: Pangea!
I. Population Growth
Video: How did we get so big so fast?
A. Demographic Vocab Crude Birth Rate (CBR) # of births per 1,000 ppl Influenced by age, development, culture, laws
Crude Death Rate (CDR) How many people die per 1,000 people Infant mortality rate: infants 1 year and younger die per 1,000 live births
B. Natural Increase Rate (CBR-CDR) / 10 =NIR Current NIR on Earth: 1.2 NATURAL= birth not migration
3. Doubling time: how long it takes to double the population 2. 7.046 Billion people on Earth 3. Doubling time: how long it takes to double the population
C. Fertility Total Fertility Rate (TFR) = Average # of babies a fertile woman will have More accurate than CBR CBR = population right now TFR = population in future
2. Replacement Level Fertility: # of babies born ensure the same # of women will survive to have babies So no population increase! Your population stays the same You are replacing yourself
How do you think the development of a country affects the CBR & CDR? Discuss How do you think the development of a country affects the CBR & CDR?
D. Population Density Arithmetic Density: Crude density, population ÷ unit of land area Physiological Density: # of ppl a unit of arable land can support Agricultural Density: # of farmers to unit of arable land
DRAW THE FOLLOWING SLIDE
Agricultural Arithmetic Physiological Density Density Density Country of BOX - Population: 6 Area: 6 sq miles LAVA 1 person per 1 Mile 3 people per 1 Mile of ARABLE LAND 1 FARMER per 1 Mile of ARABLE LAND Arithmetic Density Physiological Density Agricultural Density
Using your knowledge about the different types of Density… Check - It Using your knowledge about the different types of Density… Create a poster that teaches a Kindergartener the following… Different Types of Density How to use the different types of density What each density looks like Why each one is important
Ticket Out the Door: Explain the ways human geographers analyze population change. Describe the relationship between population growth, population density and development.
