I’ve noted before that the baby boomer generation can and will have a significant impact on the stock market. It already has, and I will blog about that some other day.

The question today, however, is CAN the boomers really have an impact. I could go through economic models and simulations, or historical data and trends to show it to you, but I leave that for the book “The Coming Crash: How a House of Cards Will Fall as We Pull Out the Foundation.”

However, there is a simple way to see that there will be an effect: consider the raw SIZE of the baby boom generation. Boomers consistent of 80 million people in our population.

In this day and age where we throw around the words millions, billions, and trillions, but rarely if ever actually count up past twenty ourselves, what is 80 million?

There are lots of ways to understand what 80 million is, but to see the impact on the stock market, consider the following:

The population of the cities of: New York , Los Angeles, Chicago, Houston, Philadelphia, Pheonix, San Diego, Dallas, San Antonio, Detroit, San Jose, Indianapolis, San Francisco, Jacksonville, Columbus, Austin, Baltimore, Memphis, Milwaukee, Boston, and Washington combined is only about 30 million – less than half the total baby boomers. Why these cities? They are the 20 most populous cities in the entire United States according to the 2000 Census!

In other words, the 20 largest U.S. cities would only account for less than half the baby boomers!

Imagine what would happen if all the people in the 20 largest U.S. cities took their money out of the stock market, and then took out money for someone else too.

The thought is staggering. The effect is large. Detailed computer simulations combined with historical data show it is inevitable, as the tidal wave of retirees hits. The only question is how to best prepare yourself.
