Last week’s terror attacks in Paris highlight the tension in Europe between secular Europe and those believing in Islamist values. The Economist looked at some of the available data and noted the gap between Europe’s perception of Islam and its reality. A quick figure called out for France, French respondents thought 31% of the French population to be Muslim. The reality is a mere 8%.

Today’s post looks at peak income for the middle class. The Washington Post looked at peak median household income for each county in the United States. And for 81% of counties, that peak was over 15 years ago.
The really nice features of this piece are not actually the map, which is a standard choropleth map. Instead small multiples above the map breakdown the appearance of counties in each era bracket. And then to the right the user can compare a selected county against both the state and the United States. Overall, a very nice piece.

I apologise for the lack of posts over the last two weeks, but I was on holiday. Naturally, I have returned just in time for some snowstorms in the Midwest. But today’s piece comes from WGN and it explains how the type of winter precipitation that falls depends not solely on ground temperatures. Rather, temperature profiles in the upper atmosphere can make all the difference between rain, sleet, and snow.

We hear a lot about deforestation around the world. But, in this piece from the Washington Post, we see how over the last century, Europe has actually managed to reverse that trend and reforest parts of the continent.
Today’s piece comes via a colleague. It is an article about hit-and-run cycling accidents in and around Los Angeles. The data visualisation in the article is not entirely complex—we are talking only about line charts and bar charts—but they support the arguments and statements in the article. And in that sense they are doing their job.

Last week, there was a disruption at the air traffic control centre for the United Kingdom. It caused many travel problems. And the BBC included a graphic showing how the problem was shutting down London air space.

To continue with the sports theme from yesterday, today we have an interactive map from Twitter that looks at NFL team popularity. The methodology is simple, where are the users following the various football teams and map that out by county. The overall blog post features a country-wide map, but then narrows down into a few particular stories. The image below is from the divide in the state of Pennsylvania between Eagles fans and Steelers fans.

A little while ago, LinkedIn put together a map looking at the disproportionately represented jobs and skills in cities in both the United States and Europe. That is different from the most common jobs but those that are “most uniquely found” in cities.
The unique skills of America’s various cities
Unfortunately the interface is a bit clumsy. For something that is about exploring different cities, I think the small area of the map could be bigger. And the highlighting functionality lags. But the overall idea is interesting.
And on a side note, while graphic design is not specifically covered, I found the list of skills for Chicago surprising. If only because I work as a designer for a company in the market research industry.
This is an old map that saw the light of day a while back. Featured on Vox, the map supports the notion that some white people are whiter than other white people. The map explores immigrant populations. Using a map for spatial arrangement of integrated components, the data looks at immigrants’ ethnic origins, their workforce breakdown, and their recent growth.
