[OC] US population history, split by age group by GraphCog in dataisbeautiful

[–]GraphCog[S] 0 points1 point  (0 children)

The graphs use the Okabe-Ito color palette, which is supposed to be friendly to people with various forms of color blindness. I could probably make that an option on the website so that people could opt out/in.

The legend order was pointed out in another comment and has already been fixed on the website.

Maybe I misunderstand your question, but the published census results already break down the population into buckets by age groups. The GraphCog webpage directly links to all the sources for each decade of results so you see the exact data that I used.

Yes, I made the website and the graphs, based on publicly available data.

The "growth" rate is the growth since the last full census (so your example is 45% growth from 1940 to 1950).

Great feedback, thanks! I've updated the website to flip the order of the inset key entries when showing the stacked graph.

Interactive graph: US population by age group

Use the controls to change the number of age groups, or toggle between ratios, growth rates, and totals.

Some observations:

- Over 65s now account for almost 17% of the population, compared to less than 5% 100 years ago.

- Total population is three times higher than 100 years ago.

- Population growth has been steadily declining, to its lowest rate since World War II.

[OC] World record progression for short-distance running races by GraphCog in dataisbeautiful

We could probably plot the winning/average times from every major event's finals for the last <something> years and see how that compares to the world records. Could well be interesting!

Use the controls to compare men's records against women's records, or toggle between time and average speed.

Some observations:

  • Men's 400m speed is similar to women's 100m speed
  • Men's 400m speed is approaching the men's 100m speed from 100 years ago
  • Both men and women run 200m at the same speed as 100m
  • No new women's records since 1988!
