The Population of Every Country is Represented on this Bubble Chart
The beautiful thing about data visualization is that it can appear deceptively simple.
The world is infinitely complex and burgeoning with all kinds of information. As a result, it seems counterintuitive that things can be reduced to a basic bubble chart or a graph – and to be fair, most things can’t.
When the opportunity does arise, however, the results can be very compelling and thought-provoking. A distilled story can help create insight around a subject that wasn’t possible when looking at it with more nuance and complexity.
The Population of Every Country in Bubbles
Today’s visualization comes from Datashown, and it helps to give some perspective on world population.
It’s a deceptively simple visualization, but the story that gets distilled is loud and clear:
The beauty lies in the simplicity – and although all countries are represented, only the labels of the biggest are shown.
If you want to dive into the granular data, here is an interactive version of the same diagram, with all countries and population statistics embedded.
Zooming in on the United States
On the above bubble chart, envision “zooming in” on the circle representing the United States, which is located just below China and India.
Here’s the population of every U.S. county in interactive form, from Overflow Data. Highlight any circle (or use the search function) to find the information on a particular county:

Ivy League institutions are renowned worldwide for their academic excellence and long-standing traditions. But how hard is it to get into one of the top universities in the U.S.?
In this graphic, we detail the admission rates and average annual cost for Ivy League schools, as well as the median SAT scores required to be accepted. The data comes from the National Center for Education Statistics and was compiled by 24/7 Wall St.
Note that “average annual cost” represents the net price a student pays after subtracting the average value of grants and/or scholarships received.
Harvard is the Most Selective
The SAT is a standardized test commonly used for college admissions in the United States. It’s taken by high school juniors and seniors to assess their readiness for college-level academic work.
When comparing SAT scores, Harvard and Dartmouth are among the most challenging universities to gain admission to. The median SAT scores for their students are 760 for reading and writing and 790 for math. Still, Harvard has half the admission rate (3.2%) compared to Dartmouth (6.4%).
| School | Admission rate (%) | SAT Score: Reading & Writing | SAT Score: Math | Avg Annual Cost* |
|---|---|---|---|---|
| Harvard University | 3.2 | 760 | 790 | $13,259 |
| Columbia University | 3.9 | 750 | 780 | $12,836 |
| Yale University | 4.6 | 760 | 780 | $16,341 |
| Brown University | 5.1 | 760 | 780 | $26,308 |
| Princeton University | 5.7 | 760 | 780 | $11,080 |
| Dartmouth College | 6.4 | 760 | 790 | $33,023 |
| University of Pennsylvania | 6.5 | 750 | 790 | $14,851 |
| Cornell University | 7.5 | 750 | 780 | $29,011 |
*Costs after receiving federal financial aid.
Additionally, Dartmouth has the highest average annual cost at $33,000. Princeton has the lowest at $11,100.
While student debt has surged in the United States in recent years, hitting $1.73 trillion in 2023, the worth of obtaining a degree from any of the schools listed surpasses mere academics. This is evidenced by the substantial incomes earned by former students.
Harvard grads, for example, have the highest average starting salary in the country, at $91,700.
