This blog is intended to go along with Population: An Introduction to Concepts and Issues, by John R. Weeks, published by Cengage Learning. The latest edition is the 13th (it will be out in January 2020), but this blog is meant to complement any edition of the book by showing the way in which demographic issues are regularly in the news.

You can download an iPhone app for the 13th edition from the App Store (search for Weeks Population).

200 Countries, 200 Years, 4 Minutes

In a previous posting, I pointed you to a video featuring Professor Hans Rosling of Sweden as he took us visually through population growth from 1960 to the middle of this century. Now he's back with a new video called "200 Countries, 200 Years, 4 Minutes," which in four minutes dramatically visualizes the improvement in life expectancy over the past 200 years, using data from 200 countries (albeit not all countries have data for all years). This video is part of his BBCFour series on the "Joy of Stats" and it is available on the internet from:  Enjoy!
