Thinking Tool for Examining Demographics (Study of Changes in Population)

This page provides a template you can use and two examples. Among the applications for the template that you might find useful are:

§         What happens after the change in immigration law in 1965 and what happens with the next generation of these immigrants?

§         What happens with the consumer society?

Example: Baby Boomers

Look at the chart and ask yourself:

1.       When do the boomers consume goods and services, but not need a job?

2.       When will there be a bubble of more students in the public schools?

3.       When will they be teenagers and what do teenagers do?

4.       When will they go to college and/or the age when Selective Service applies to them?

5.       When will they need a job to be able to be able to support themselves—to be able to consume?

6.       When will they have babies—and a mini-baby boom will start?

7.       When do the boomers hit their 60s?

Example: People Who Had Seen the Economy Collapse with the Great Depression

Reminders: The stock market crash hits in 1929; the Great Depression lasts for the next decade.

 

Look at the chart:

§         The rows are for those who directly experienced how quickly and how deeply an economy can fail.
The rows are for people who are at least 1 when the crash hits and up to 25 when it hits.

§         The shading shows the decade each age group becomes 60 within the decade.

 

Look at the chart and then look at the economic events that occur the decades after that shading? Does that tell you anything (including the value of learning history)?
