Population Pyramids

Review

In class Tutorial

Break into groups so that it is balanced with people who were present for the lesson with people who were absent for the lesson.

Using the next 2 graphs spend a few minutes in your group talking about a population pyramid. Include:

1. Where to find the male & female information 2. Where to find the total population 3. Where to find the age data 4. The differences between a graph for an MDC and and

LCD or LLDC 5. Three pieces of information or generalizations you can

make about a graph.

?

What you should be able to pick out…

LDC High birth and death rate means that this is

an LDC Sudden decrease in population from 20

onward. Low education/health care

What you should be able to pick out…

MDC Low birth and death rates mean an MDC Relatively high senior population means

good health care Slightly more senior females than males is

average for an MDC

Try this one on your own

Look at the following graph. On a piece of scrap answer the following: MDC or LDC? How do you know? What could you say about this nation? Once completed trade your sheets with

others to correct them and give them back.

Try this one on your own.

Try this one on your own…

LDC (Ethiopia) High birth and death rates Pyramid gets smaller at the top due to poor

health care and natural mortality FYI – the sharp decrease in population from

0-4 and 5-9 is due to child mortality. If children die here they will usually die before their 5th birthday. This happens at a rate of roughly 1.5 – 2 million a year.

Try this…

Get a piece of graph paper from the teacher to graph the data on the population data sheet

Label the graphs Country 1 and Country 2 You may do this in pairs but no more. On the back answer the following: MDC or LDC? How do you know? 2 predictions

about the country… Be prepared next class to do one on your own.
