I am currently (re)writing our online course on marriage and family (a topic I generally stay away from but them’s the breaks). However, as usual, I decided to integrate a module on data exploration. I stumbled upon this Pew research report on global aging that contained a lot of information and data, so I thought I’d just share some of what I found interesting.
First of all, I find this interactive visual very useful as an introduction the state of the world population by age groups, from 1950 to 2050:
You can either examine data for the US (numbers and percentages) or the world. Focusing on percentages, for the global population, you can clearly see which age group is projected to grow or shrink. So, for instance, the 15 to 64 population is stays pretty much stable from 1950 to 2050 (from roughly 61 to 63%). The under 15 category peaks in 1965 (with 38%, the end of the baby boom) but projected at just over 21% by 2050. However, for the 65 and older age group, the shift is from about 5% in 1950, to 15% projected for 2050. These increases and decreases are clearly visible just by eye-balling the graphic. Switching to the Us, that shift to a “geezerification” of the population is even clearer. as it is for most wealthy countries.
The global overview is nice but only as a starting point. There is some need for some fine-tuning by country and since my main topic here is aging, let’s look at that, for selected countries
Let’s do that below the fold:
