So Young, So Old

Nathan Yau at Flowing Data has produced an interactive graphic to compare your age with others. What percentage of the US population is younger than you? What percentage is older? In the static image above the US median age appears to be about 37 years old. Based on a 5-year American Community Survey from 2014, his interactive graphs lets you slide the line to match any age and see the percentage of Americans older or younger.

Changing Wants

Research in the Journal of Family Issues by Boxer et al. was illustrated by Max Roser at Our World of Data in the graphic above. From survey results that date back to the 1930s, college students ranked the importance of 18 traits of a prospective mate, via datavizblog, via techinsider.

Here are the ranking results from Boxer et al.:

Their research questions wondered if more recent surveys from 1985, 1996, and 2008 showed increasing importance to men of "good financial prospect." It had only partial support. Their next question wondered if there was increasing importance among women for "good cook and housekeeper" and "desire for home and children". It had no support. Finally, they wondered if there would be decreasing importance among women for "good financial prospect". It had no support.

The graphic above takes their widest view of mate preferences where "mutual attraction - love", "education - intelligence", "sociability", "good lucks", and "good financial prospect" have increased in importance since 1939 for both sexes. "Desire for home, children" has increased for men but decreased for women. And for men "ambition and industriousness" has dropped since 1939. "Chastity" has decreased in importance for both sexes.

Semester's End

It's the end of the semester and I saw this Post-It Note graphic that shows exactly how many people, especially students, approach an assignment's deadline. From Instagrammer Insta-Chaz via Visual News.

Happy Deathday Will?

In honor of William Shakepeare's 400th deathday, An infographic from Raconteur showing a timeline of the World's Greatest Storytellers (compete with local magnification) as surveyed by authors, journalists, writers, and students. The size of the bubble corresponds to the number of votes. Shakespeare looms large overall as the greatest story teller of the all. Happy Death-day Will.

(Earlier I posted Happy Birthday wishes, misled as others were on the web, but I was wrong. It is Will's Deathday and I corrected my posting, although I thought only Saints were to be remembered on their Death-day. Shakespeare was a genius, but I don't think many would call him a Saint).

Flag Graphics

Design agency ferdio has put together graphics illustrating the design, colors, and symbols of national flags. Patterns, layouts, ages etc. are collected together in what they have call Flag Stories. Above is one such story of flags stacked into a bar chart showing the frequencies of the number of colors in the flags. As they mention, over a third of countries favor flags with three or four colors. You can find many more at Flag Stories. We've seen flag colors before.

March Madness: It Didn't Happen Yet Again

It didn't happen yet again. In last month's NCAA "March Madness" men's college basketball championship, a number of 16 seeds have again failed to best the number 1 seeds. The histogram above shows the score differences in such matchings since 1985. It closely matches a normal distribution, allowing for us to estimate the probability that such an upset could happen as the area under the approximating bell-curve that falls beyond zero. Our estimated probability that a number 16 seed would beat a number 1 seed is 0.0208. It has risen a bit since our last view.
