“What a Real ‘Brexit Britain’ Would Look Like”

“The United Kingdom is 94,525 square miles — about the same size as Romania or, to put it in U.S. terms, Michigan. If Scotland, Northern Ireland and London all left, it would be closer to 58,000 square miles — slighter bigger than Bangladesh and about the size of Iowa.”

Last week, Britain voted to leave the European Union. Well, at least part of it did. If you look at the map above, it’s hard to miss the geographical split among British voters in the E.U. referendum results.

“How the Red and Blue Map Evolved Over the Past Century”

If this year’s presidential election is at all competitive, we will see the major candidates zero in on a handful of “battleground” states and ignore most of the United States. The red-versus-blue electoral map has changed little since achieving iconic status in 2000; all but 10 states have repeated their choice of party three times.

Charting New York City’s Changing Borough Population, Over Time

By Matt Stiles | | Topics: Demographics

I woke one recent morning at 5 a.m. obsessing about, of all things, the people of New York City — specifically how the population is distributed among the five boroughs: Brooklyn, Bronx, Manhattan, Queens and Staten Island. And how that’s changed over time.

I had a general idea. But my nerd brain needed to know for sure. So I went to Wikipedia for data. These charts show the total population, by borough, since 1790.

This chart shows how the proportion of New York City residents in each borough has shifted over time. Decades ago, Manhattan was the center of population. Not anymore, of course:

“What the Census Tells Us About America Today”

“Four states are majority-minority: Hawaii, New Mexico, California and Texas. In contrast, Maine, Vermont and West Virginia are the least diverse states.”

America is changing rapidly. The country is older, more diverse and more likely to be multiracial. New Census data show what statistics will make up the current and future America. The Census has predicted that by 2044, more than half of Americans will belong to a minority group (any group other than non-Hispanic, whites).

“The Partisan Divide in Gun Legislation”

Since 2015, members of Congress have proposed 100 civilian-focused gun bills, 56 aimed at increasing gun control and 44 that attempted to expand or protect Second Amendment rights. None have passed both houses. [ Here’s what lawmakers talked about in the wake of the Orlando mass shooting] Below are the 503 lawmakers, 94 percent of Congress, who sponsored or co-sponsored gun legislation this session.

NFL Geography: Where Were Professional Football Players Born?

By Matt Stiles | | Topics: Demographics, Sports


Are states proportionally represented on the historical list of National Football League players? That’s the question I had four years ago when I posted two simple state-by-state maps summarizing players’ birth places.

That post has been surprisingly popular, so I decided to remix the visualization a bit — replacing the old choropleth maps with tile grids.

How Much Differently Do Men and Women Drink Alcohol — By Country

By Matt Stiles | | Topics: Demographics, Uncategorized

A few months ago, I wrote about the novelty of a McDonald’s selling beer at one of its restaurants in South Korea — a first for the fast-food giant in Asia.

The story wouldn’t have been complete, of course, without the context of South Korea’s raging alcohol consumption. People who drink here do so more heavily than their counterparts in most countries around the world, especially when compared to fellow rich nations, according to a survey by the World Health Organization.

The country-by-country comparisons from that story are plotted below.

“Communicating with Data – Timelines”

“I did not draw this graphic by hand. And yet it is not a chart type offered very often by today’s software chart wizards. It was produced using d3.js…”

Anyone faced with a design challenge will recognise “the feeling” – something is not quite right, yet it is difficult to put your finger on the problem. Here is an example from a story recently featured in the FT…

Editing O.J. Simpson: Charting Changes to His Wikipedia Page

By Matt Stiles | | Topics: Crime, News, Sports

I’ve just finished watching ESPN’s fabulous O.J.: Made in America, a five-part documentary about the Hall of Fame football player.

Somewhere in the process of digesting this latest — and, perhaps, best — telling of O.J.’s story, I scoured Wikipedia for details about his life. I discovered that the page has been edited more than 4,000 times since it went up in 2003, back when Wikipedia user “Vera Cruz” posted the first biographical snippet.

Since then, users have slowly edited — and vandalized — the current bio’s 5,000 words, a process I’ve charted below.
