The civic dashboard

On Friday my local paper ran a story entitled Keene crime rates steady over years. Because that link will go dark soon, I’m going to assert fair use for the part of the story that cites statistics:

Strings of vehicle break-ins and vandalism and the occasional vicious beating or stabbing may lead some to believe that Keene’s streets are getting meaner, but crime statistics show little change over the last six years.

Even in light of rough economic times, which typically parallel a spike in shoplifting — people begin stealing groceries or other necessities they can no longer afford — the Elm City’s property crime rate remains stable.

The city’s social programs, such as The Community Kitchen, which provides food to area residents in need, play a significant role in curbing crime, Keene police Lt. Jay U. Duguay said.

“We’re behind the nation when it comes to economic issues. People are still losing their homes and jobs, but overall we haven’t felt the effects of it yet,” he said. “Right now it’s wait-and-see.”

During the last six years, Keene police have received an average of 490 reports dealing with larceny or theft. Last year they took 667 reports of larceny or theft, the highest number of those types of crimes since 2002, which saw 604 reports.

From the beginning of this year to the end of April, there were 202 reports of larceny and theft, slightly higher than the 147 during the same period last year, and 33 burglaries, which is on par with previous years.

“There’s going to be periods with a little influx, but for the most part it’s steady,” Duguay said. “I was actually kind of surprised at how consistent the numbers were.”

In 2004 and 2005, property crime rates dipped dramatically. While 2003 saw 557 larcenies and thefts, that number hit 272 the following year and then slightly increased to 286 the next year before rising to 455 in 2006.

“We didn’t change our patrol procedures during those times (2004 and 2005) and we weren’t up to full staff. So I don’t know why those years are lower,” Duguay said. “I think the more consistent number is the high number, but thank goodness for the lows.”

Violent crime reports in Keene have also remained steady over the last several years, with an average of 366 assaults annually.

Between 20 and 30 sex assaults are reported in the city each year, though only a small fraction of those cases result in arrests because the others lack sufficient evidence, Duguay said.

Statistics only tell part of the story, though. For the crime victims, the numbers hold little meaning.

The story concludes with anecdotes from townsfolk who either do, or don’t, believe that tough economic times are making Keene’s streets meaner.

I quote at length from it here because I think it captures a moment in time. The story seems to be data-driven, but not in the way that many of us now realize such stories can be. The reporter got some numbers from the police department, and the story quotes a lieutenant’s interpretation of those numbers, but there’s nothing available for an interested citizen to verify or falsify. And there’s no reference to an alternative source — from the US Bureau of Justice — that could confirm, challenge, or otherwise contextualize the numbers.

I hope that my response, below, also marks a moment in time — one in which people didn’t demand, governments didn’t provide, journalists didn’t exploit, and all these groups didn’t collaboratively engage with more and better evidence than informs most civic dialogue today.

From time to time, communities ask: Are we having a crime wave? A couple of summers ago it seemed that way. The Sentinel invited TalkBalk comments, and one person wrote: “Keene has gone downhill. Once a peaceful, quaint city that was safe, it is no more.”

We shouldn’t have to just speculate about these trends though. We should be able to look at the data and draw reasonable conclusions. Increasingly, we can.

In 2007 I looked, and the first source I found was the data reported by the Keene police department (and every other police department around the country) to the US Bureau of Justice. I noticed a couple of things. First, the numbers showed no uptick in violent crime. But since they stopped in 2005, they didn’t address concern about events in the then-current 2006-2007 period.

Second, because the numbers went back to 1985, they revealed a remarkable anomaly. There was a huge spike in violent crime — assaults and rapes — from 1990 to 1994. You can see the trend plainly in the charts and data I’ve posted at http://jonudell.net/crime/keene-crime.html. What happened then? How should this historical context influence our perception of current trends? I’d love to see the Sentinel ask, and try to answer, these questions.

Since the Bureau of Justice data wasn’t current enough to address the 2006-2007 concerns about crime, I asked the police department to provide me with more recent data. In the end, after multiple requests and some nudging by an attorney, they complied. The snapshot I received, with numbers through July 2007, showed no evidence of a recent uptick in either violent crime or property crime. That was
reassuring.

It was also enlightening to compare the raw data in the police spreadsheet to the numbers reported to the Bureau of Justice. They don’t exactly line up. This isn’t nefarious, it’s just what happens when local systems try to mesh with national systems. There is a lot of local variation in the classification of different types of crimes, and room for interpretation when you bundle them into larger
categories.

Fast forward to summer 2009. The economy has tanked, and people are again wondering whether we’re having a crime wave. The Sentinel gathered some data, talked to the police, and concluded — I suspect correctly — that as before, the perception of a crime wave is not the reality.

For the reasons I’ve explained, the police department numbers reported in the Sentinel don’t quite line up with those reported to the Bureau of Justice. Consider larceny-theft, for example:

          2003   2004   2005   2006
Sentinel   557    272    286    455
Justice    534    245    235    622

But I do wonder about this:

“Violent crime reports in Keene have also remained steady over the last several years, with an average of 366 assaults annually.”

I hope that’s an error. According to the Bureau of Justice there were at most about 100 violent crimes per year, back in the dark ages of 1990-1994, and we’ve averaged between 40 and 60 per year from then until 2007.

In any case, here’s the larger point. Cities around the country have begun to realize that the operational data of city government can be made available to everyone — citizens as well as journalists — so that we can all monitor the health of our cities in a collaborative way. Crime statistics are one popular category of data, others include restaurant inspections, infrastructure repairs, and licensing.

Nowadays it costs about $100/month to augment a police department’s information system with software that reports current crime statistics online, and also displays the locations of crimes on a map. In New Hampshire, one such system (crimereports.com) has been installed in Exeter, Hampton, Laconia, and Rochester.

I’d love to see the Keene police department join that club. A civic dashboard is part of what I proposed during the Community Visioning Process. But there’s no need to wait until 2028. Cities around the country are creating their dashboards now, and we can too.

  1. Bang on, Jon. Great piece. We REALLY need to start focusing more educational resources on real-world numeracy, especially in the area of statistics (including visualizations) and probability. It’s relevant to economic, personal, and political decisions that are made every day.

    I recently watched a short TED piece where Arthur Benjamin made this point exceptionally well: http://friendfeed.com/kenzoid/db87c0be/arthur-benjamin-formula-for-changing-math

    This needs to happen, and the sooner the better. Better understanding via education, better tools via mashups, Web 2.0 services, and emerging frameworks, and better data via the opening of information systems as you advocate above.

    My fingers are crossed!

  2. You’ve done a great job at outlining some of the key issues behind the current transparency of crime information and the need for our law enforcement officials to have quick access to relevant information to help increase force effectiveness and keep the public informed.

    As you point out, the good news is that citizen-level crime data is becoming more readily available from police services today in the form of dashboards and visualization maps that take information from a variety of systems and highlight, with accuracy, real crime patterns down to the local neighborhood. Modern analytics technology combines with police systems to make this possible. It is even at the point where police officers have this information at their fingertips, via mobile devices, so they can see the week’s or previous days crime hot spots for their specific beat.
