An analysis by Raj Chetty of Harvard University and Nathaniel Hendren of NBER estimates increased income and education for poverty-level households, based on where one lives. The results are based on tax data — 1040 and W-2 forms — from the IRS, and the focus of the analysis is on those who moved from one county to another.

The main finding was that location matters. The Upshot mapped the results, with an article whose text changes based on the county you select.

There’s a lot of data readily available online. We know this. However, there’s also a lot of data available that’s offline, sitting on people’s hard drives. You just have to ask for it — in the right way. Christian Kreibich, a researcher for the International Computer Science Institute, provides a guide.

Dominik Schwarz wanted a big world map. A really big one that covered his entire wall in high detail.

You can get great world maps up to around 1,50m (~59 inches) width. However, this size seems to be a tipping point. From here on the bigger the maps get, the less detailed they are. And it makes sense. Such big maps are normally used in classrooms and even the people in the last row should see the large printed city names.

But that’s not what I wanted. Not at all. I envisioned a gigantic poster that would show the smallest villages, the most detailed coast lines and the highest level of information density possible.

He outlined his process from grabbing the data to printing to final mount.

The median home in America has changed in a variety of ways. Square footage increased, number of bedrooms and bathrooms shifted, heating changed from electrical to gas, and cost went up. CNNMoney provides an animated graphic that shows these changes over the past four decades.

The earthquake in Nepal was big, but there’s a discrepancy in just how big. The United States Geological Survey (USGS) measured the earthquake at 7.8 magnitude, whereas the China Earthquakes Network Center (CENC) measured it at 8.1. The three-tenths difference doesn’t seem like much, but the latter is actually an earthquake that exerts twice the energy of the former. Akshat Rathi and David Yanofsky for Quartz explain in a lesson of the logarithmic scale and earthquake magnitude.

Fashion trends, such as skinny jeans and Palazzo pants, can spike and fall quickly year over year, and it can be tough to keep up. Maybe trends in Google searches for specific fashions can help. Hiroko Tabuchi and Josh Katz for the New York Times mapped a handful of fashion searches over time so you can see some of the regional changes.

An earthquake with a magnitude of 7.8 can affect countries differently, depending on the people’s ability to withstand and recover from such a disaster. INFORM attempts to assess this risk, so that organizations can make better-informed decisions about what relief to send. Greg Myre for NPR explains with a heatmap. [via @onyxfish]

The talks from OpenVisConf 2015 went up, so I’m slowly making my way through. In this one Danyel Fisher from Microsoft Research talks about the challenges of working with data that doesn’t quite fit into your standard CSV data model. The visualization has to account for the mess.

Winter is over and it’s shorts weather these days in California. This is good for relaxing outdoor lunches but not so good for the drought. It’s sad to drive down the state and see a bunch of barren farm land. Victor Powell shows this shift in water supply through reservoir data from the California Department of Water Resources.

A while back Alex Reinhart, a statistics instructor and PhD student at Carnegie Mellon University, was working on a guide for doing statistics right. The goal was to teach through anecdotes of statistics done wrong, from statistical significance and p-values to regression and confounding factors.

Statistics Done Wrong is a book now. If you analyze data with any regularity but aren’t sure if you’re doing it correctly, get this book. It’s a concise guide with interesting examples and a light, easy-to-read tone.
