EQ 5: What factors effect Population Structure? 2/22

EQ 5: What factors effect Population Structure? 2/13 Bell-ringer: 1. Why might a country have both a high CBR and a high CDR? 2. Why might a country have a high CBR, but a low CDR? 3. Why might a country have a high CDR, but a low CBR?

Total Fertility Rate (TFR) Average number of children a women will have Prediction: Where do you think the highest and lowest total fertility rates are Explain two reasons why you think this true.

Where are the lowest and highest rates Where are the lowest and highest rates? Fill in your chart and shade the maps.

Infant Mortality Rate (IMR) The annual number of deaths of infants under 1 yr of age for every 1,000 live births Prediction: Where do you think the highest and lowest infant mortality rates are? Explain two reasons why you think this true.

Which continents have the highest/lowest IMR Which continents have the highest/lowest IMR? Fill on your chart and shade maps.

Life Expectancy Measures the average number of years a newborn infant can expect to live Prediction: Where do you think the highest and lowest life expectancy rates are Explain two reasons why you think this true.

Where is life expectancy the highest and lowest Where is life expectancy the highest and lowest? Fill in your chart and shade map

REFLECTION Choose an area of the world. Write a summary of its population structure including the following terms: CBR, CDR, NIR, IMR, TFR, Life Expectancy Make sure you explain how and why these are related.

EQ 5: What are Population Pyramids and why do they differ. 2/14 EQ 5: What are Population Pyramids and why do they differ? 2/14* Bell-ringer: What information is this graph displaying? What can you infer from the graph? What questions do you have?

Vertical axis: Age groups LEFT – MALE; RIGHT-FEMALE Elderly Dependents Working populations Young dependents Horizontal Axis: Percentage/number people At the top: country and year

Annotate the graph- Write questions Annotate the graph- Write questions. Make 3 observations and 1 inference of this population pyramid (on ws)

Compare this graph to the previous. Write any questions you have Compare this graph to the previous. Write any questions you have. Write 3 observations and make 1 inference.

Making connections! What are 3 differences between the two population pyramids? What has happened between 1950 and 1995 that could explain the difference between the two pyramids? (make 2 inferences)

Population Pyramids in the US handout Read the helpful hints (on your tables) and determine which population pyramid represents each location Think about what each places population would look like based on what is located in that city Put the correct letter and explanation of the place in the blank space next to the number Choose 2 and explain why you chose what you did using evidence from the pyramid

EQ 5: What are Population pyramids and why do they differ EQ 5: What are Population pyramids and why do they differ? (same as yesterday) Bell-ringer: Look back in your notes, what information is found on a population pyramid? Explain why two pyramids may look different from one another. This could be a difference in year or location. (write a 1 paragraph response to the questions above)

What does the pyramid shape explain about the population? If the pyramid looks like a pyramid, the population is …….. If the pyramid looks like a V, the population is ………. If the pyramid looks like a box, the population is ………

What does the pyramid mean? If the pyramid looks like a pyramid, the population is increasing. If the pyramid looks like a V, the population is decreasing. If the pyramid looks like a box, the population is stable (not growing or shrinking).

Create your own population pyramids Each partner will use a different country so you have 2 pyramids to compare and contrast Look at the two tables of information. Which columns of information do you need to make your pyramid? How will you start it? GO! Make your pyramid!!

Compare and contrast On the back of your sheet: Look at both pyramids and write 3 differences Bolivia: Describe the shape of the pyramid? What does this mean about their population? Explain what type of country (developed/developing). How do you know this? EXPLAIN WHY-at least 2 reasons Repeat for Canada

Reflection Make a list of 3 specific factors/reasons that could affect pyramid structures for the different countries. (do not write CBR and CDR-write what could cause these rates to change)

Do geographers believe India’s population will increase or decrease from today?? What type of country is India? Why?

War deaths per country since WWII Make 2 observations and 1 inference about the map below

Democratic Republic of Congo 2014

Look at these population pyramids for different U.S. cities… What do you think is in each of these cities that would cause the population pyramid to look the way it does?
