“This Map Shows the Explosive Growth of Underwater Cables that Power the Global Internet”

Despite decades of growth, demand for more and faster internet connections continues to skyrocket. According to Cisco, by the end of this year total internet bandwidth will exceed a zettabyte. (A one with 21 zeroes behind it.) That’s enough bandwidth to stream approximately 143 billion hours of Netflix video at Ultra HD quality.

New Poverty Data Show Improving Economic Conditions in States

By Matt Stiles | | Topics: Economy & Finance

Economic conditions continue to improve in America’s states, with many showing significant declines in their poverty rates, according to new survey data released recently by the U.S. Census Bureau.

About 14.7 percent of the American population had incomes last year that were below their respective poverty levels, which vary depending on household size — a significant decline from 2014.

“Watch How Fast the World Became Obese”

New to me. Interesting. Would like to see the data outside the context of a map, though.

Over the last 40 years, obesity rates around the world have ballooned. The average adult today is 3x as likely to be obese compared to the average adult in 1975. This map shows how it happened, country-by-country. The color of each county represents its adult obesity rate in the year shown.

Charting American Birthdays: Yours Probably Isn’t That Special

By Matt Stiles | | Topics: Demographics, Policy & Politics

Last week I published a new heatmap exploring the popularity of American birthdays. The chart, which uses darker shades to represent higher average birth counts on specific days, can give the impression that some birthdays are much more common than others.

In reality, outside of some special occasions, namely major holidays, there isn’t a huge amount of diversity in the data set, which has two decades of births aggregated by day. Most birthdays, including my own, are fairly average — especially in the first six months of the year. For example:

How Common is Your Birthday? This Visualization Might Surprise You

By Matt Stiles | | Topics: Demographics, News

It’s baby season in America, with September the busiest month for births on average in the last two decades. So it seemed like the right time to remix this blog’s most-popular post: How Common is Your Birthday?

That old heatmap, which highlighted specific dates for popularity, has been viewed more than 500,000 times here and published across the web. But it was flawed, namely that it used ordinal data (birthday ranks by date) rather than continuous data (actual births counts by date). This graphic finally addresses that problem:

“A Detailed Look Of Gay Marriage In the United States”

More than three years after a Supreme Court decision gave federal recognition to same-sex marriages performed in states that allowed them, the demographics of same-sex married couples largely remain a mystery. But a new research paper published by the Treasury Department on Monday has found an interesting way around these problems: tax records.

“Clear Off The Table”

The principles outlined in that article aren’t just for charts, though. You can apply them to your data tables with similar improvements in readability and aesthetics. To paraphrase Edward Tufte, too often when we create a data table, we imprison our data behind a wall of grid lines. Instead we can let the data itself form the structure that aids readability by making better use of alignment and whitespace.

Poll: Trump-Clinton Matchup Redrawing Electoral Map

This poll is major undertaking for The Washington Post, and its graphics team did a nice job explaining some of the key findings.

A Washington Post-SurveyMonkey poll of all 50 states indicates the 2016 campaign could flip several red and blue states from their longtime loyalties. The poll, conducted Aug. 9 through Sept. 1, asked more than 74,000 registered voters who they currently support for president.
