Five steps to let the young ones shine

Knife stabbings are in the news in the U.K. and the Economist has a quartet of charts to illustrate what's going on. I'm going to focus on the chart on the bottom right. This shows the trend in hospital admissions due to stabbings in England from 2000 to 2018. The three lines show all ages, and two specific age groups: under 16 and 16-18. The first edit I made was...

The Crime Machine

I’m behind on my podcast listening (well, behind in everything tbh), but Reply All covered the flaws of CompStat, a data system originally employed by the NYPD to track crime and hold officers accountable: But some of these chiefs started to figure out, wait a minute, the person who’s in charge of actually keeping track of the crime in my neighborhood is me. And so if they couldn’t make crime...

Two good charts can use better titles

NPR has this chart, which I like: It's a small multiples of bumps charts. Nice, clear labels. No unnecessary things like axis labels. Intuitive organization by Major Factor, Minor Factor, and Not a Factor. Above all, the data convey a strong, surprising, message - despite many high-profile gun violence incidents this year, some Democratic voters are actually much less likely to see guns as a "major factor" in deciding their...

Is the chart answering your question? Excavating the excremental growth map

San Franciscans are fed up with excremental growth. Understandably. Here is how the Economist sees it - geographically speaking. *** In the Trifecta Checkup analysis, one of the questions to ask is "What does the visual say?" and with respect to the question being asked. The question is how much has the problem of human waste in SF grew from 2011 to 2017. What does the visual say? The number...

This map steals story-telling from the designer

Stolen drugs is a problem at federal VA hospitals according to the following map. *** Let's evaluate this map from a Trifecta Checkup perspective. VISUAL - Pass by a whisker. The chosen visual form of a map is standard for geographic data although the map snatches story-telling from our claws, just as people steal drugs from hospitals. Looking at the map, it's not clear what the message is. Is there...

Excellent visualization of gun violence in American cities

I like the Guardian's feature (undated) on gun violence in American cities a lot. The following graphic illustrates the situation in Baltimore. The designer starts by placing where the gun homicides occured in 2015. Then, it leads readers through an exploration of the key factors that might be associated with the spatial distribution of those homicides. The blue color measures poverty levels. There is a moderate correlation between high numbers...

Flawed hate crime data collection

Data can provide you with important information, but when the collection process is flawed, there’s not much you can do. Ken Schwencke, reporting for ProPublica, researched the tiered system that the FBI relies on to gather hate crime data for the United States: Under a federal law passed in 1990, the FBI is required to track and tabulate crimes in which there was “manifest evidence of prejudice” against a host...

Police surveillance in a digital world

Glenn Smith and Andrew Knapp for the Post and Courier investigate the current police practice of keeping digital record of people’s activities. Law enforcement agencies have for decades used what’s known as field interview or contact cards to document everything from sketchy activity to random encounters with people on the street. But the digital age has greatly expanded the power and reach of this tool, allowing police to store indefinitely...

The different trends in American crime

Crime is up? Crime is down? It depends on who you ask and where. The Marshall Project analyzed violent crime trends over the past 40 years to show how things are moving across the country. In the process, we were struck by the wide variation from community to community. To paraphrase an aphorism about politics, all crime is local. Each city has its own trends that depend on the characteristics...

Editing O.J.: Charting Changes to the Infamous Figure’s Wikipedia Page

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...
