“Gun Suicide and Homicide: Statistics Shaped by Race”

America’s pattern of gun deaths is split across black and white, with the vast majority of whites dying from suicide and a similar proportion of blacks dying from homicide. A similar split occurs with more homicide in diverse urban cities and more suicide in the rural areas that are predominantly white.

Charting NFL Injuries

The Washington Post has a fascinating story today about NFL players and injuries, with the local peg being Robert Griffin III’s knee injury. The gist:

Interviews with more than 50 doctors, players, agents, owners and medical ethicists suggest that what the NFL Physicians Society calls the game’s “unique clinical challenges” can result in inconsistent standards in treating players and cause some doctors to depart from best medical practices and safety norms.

These charts, which visualize the league’s injury reports over time, accompanied the story:

“The Optimal Number Of Categories In A Pie Chart”

It’s very simple, really: you do not compare proportions in a pie chart. Because a pie chart is not a comparison chart, it’s a part-to-whole chart. When you do this: what you really want to do is to compare each slice to the whole, like this: because, if you want to compare them you must do this: I hope that you find this pretty obvious.

Charting The Premier League Season

Last fall I posted some Tufte-inspired sparkline charts to visualize how Major League Baseball teams fared during the 2012 season.

I’ve created something similar for clubs in the English Premier League, where the season is winding down with Manchester United holding a strong lead in points. This chart shows how they’ve done it — by winning, not just drawing, with their opponents. United has 21 wins so far, while their cross-town rivals — Manchester City — have just 15.

Matches that end in draws are still important to a club’s success in the league, but I wanted to see their performance in wins and losses. The lines on the chart represent the total number of games over .500 for all 20 clubs. Click here to see the interactive version.



U.S. Breastfeeding Rates By Duration, Race/Ethnicity Over Time

Early this month, the Centers for Disease Control released a study analyzing breastfeeding in America, noting that the percentage of babies who were breastfed increased by four points from 2000 to 2008.

But the study showed that less than half of women were still breastfeeding after six months, the period recommended by American pediatricians. This is likely because doing so after returning to work is difficult (as my wife is experiencing now) for mothers.

Slate has more:

Breast-feeding increased across all racial groups as well, though black women still lag far behind Latinos and white women. Over 75 percent of both white and Latino infants who were born in 2008 were breast-fed, while the number of black infants breast-fed the same year was under 60 percent. Researchers checked back in with moms of 2008 babies at six and nine months, and at both points the percentage of black babies breast-feeding was much lower than the percentage of white and Latino babies.

These simple slopegraphs attempt to show the trends using the CDC’s data:

“Chart Check: Did Obama’s Graphics ‘Enhance’ His Big Speech? : NPR”

A quick project at work…

These days, Washington is crawling with fact-checkers who scour political speeches looking for errors and lies. But sometimes, even accuracy can be misleading, especially when it comes to graphics and charts. On Tuesday night, President Obama gave his State of the Union address, and the White House launched an “enhanced” experience; a multimedia display with video, 107 slides and 27 charts.

“The State of Our Union Is … Dumber”

Or just more conversational??

The state of the union address has – with few exceptions – been delivered to Congress annually since George Washington’s first address in 1790. Using the Flesch-Kincaid readability test, a US Department of Defense standard, the Guardian has analyzed all addresses to date to determine the number of years of education required to understand each speech The state of our union is …
