Picture this: US college kids – then and now
Thanks to the fascinating website Sociological Images for a pointer to this interactive map at The Chronicle of Higher Education website that presents data on the proportion of U.S. adults with a bachelor’s degree over time. In 1940, in the vast majority of counties no more than 10% of the population had graduated from college (the national average was 4.6%):
Now the national average is 27.5%:
By comparing the maps over time, you can easily track a number of changes: the increase in college degrees overall, of course, but also changes in education such as the dramatic gains women have made in earning college degrees in the past few decades — the gender gap in college degrees was over 7 percentage points in 1980 but only about 1.5 points today.
This is a wonderful example of the visual display of quantitative information that would be very effective in a presentation, similar to that used by statistician Hans Rosling.
