from the CIA Factbook to Population Pyramids

Harford County, 2000 (source: US Census Bureau) 

Here is the link to the Population Pyramids slideshow we have been discussing in class.

Also, I have included a TED-Ed video on Population Pyramids. It's more thorough and more complicated. Challenge yourself, and you might be surprised what you pick up.

Here's more: populationpyramid.net features a very cool interactive visualization of pyramids from every county (plus the entire world), and let's you pick any year from 1950 to 2100. Play around with this one and prepare to have your mind blown as you review the past and look into the future.

Finally, check out this pop/pyr for Harford County, based on figures from the 2000 US Census. Think about why it looks the way it does...
