Over the past year, Cook County, Illinois, lost more residents than other other county in the United States, according to new Census figures. It’s the first time Cook has lost population since 2007.
Even as demand for homes has grown, some Chicago neighborhoods haven’t added much housing or population.
This week we looked at why some North Side neighborhoods have declining or stagnant population gains over the past decade despite booming demand for housing. Part of the issue is the high number of multifamily buildings being demolished to make way for single-family homes.
Illinois Fails U.S. Open Data Census
Illinois is one of the worst states in the country when it comes to releasing and updating public data, according to a new study of state data holdings.
U.S. Open Data, a nonprofit working to make government data more accessible, released its first U.S. States Open Data Census this month. The group worked with the Sunlight Foundation to identify nine key datasets, and then set out to find how easy it was to access that information on state websites. Categories included legislative, incarceration, and state spending data, among others.
Illinois received F’s in every category except population projections. But even in there, the project noted the data “appears to be more than a decade old.”
Only three states performed worse: Alabama, Indiana and Michigan.
Some other findings:
In the case of corporate registration information, the organization found an up-to-date digital version but that Illinois prohibits “copying or downloading of the database information.”
While the State Assembly has information on current legislation on its website, it still got a filing grade since it’s not machine readable or available for bulk downloads.
Summary statistics are available for vehicle crashes in PDF format only, and the underlying data isn’t posted.
Nationally, U.S. Open Data also found that even when data was available, only one of four were listed in a state’s official data repository.
The report did highlight a number of states for good practices, naming Connecticut the state with the best data practices.
Chicago launches OpenGrid, latest step in making open data more accessible
Tuesday the city of Chicago released its latest open data tool, which officials hope will make it easier to find and make sense of city information.
Called OpenGrid, the platform aggregates much of the information already available on the city’s data portal, but in a more user-friendly interface.
Tom Schenk, chief data officer for Chicago, said OpenGrid grew out of an internal project called Windy Grid, which city employees used to find and visualize city data. Schenk said many of the issues for city employees are the same as the public.
“Some of the questions are fundamentally the same,” Schenk said at Tuesday’s ChiHackNight. “Why can't we leverage that to help the public?”
OpenGrid’s main interface is a map of Chicago with a search box. An advanced search area comes preloaded with common questions like nearest potholes or restaurant inspections. Searches can be limited by location, either within boundaries likes wards or zip codes, or close to a specific point.
Searches can also contain multiples datasets, so if you wanted to see if there were more rat baitings near restaurants failing their inspection, you can do that (and no, there doesn’t appear to be).
“We're making that forward progress,” Schenk said. “In the data portal you'd have to download that data and mash it up in some sort of way.”
OpenGrid is also built on top of technology created by a previous city CDO.
Last year Brett Goldstein, Chicago CDO from 2011-2013, launched Plenario, another open data tool aimed at making information more accessible. Schenk said OpenGrid can be thought of as an interface built on top of Plenario.
The technology behind both Plenario and OpenGrid is open source, meaning developers can make fixes and add features (known as “pull requests”), then have those changes incorporated into OpenGrid.
“I estimate that we've had 150 hours contributed to the city through pull requests,” Schenk said.
His hope is that since the whole stack is free, it will be easy for other cities — or any group needing to share data — could run a version with other open data or its own information.
Dan O’Neil, executive director of the Smart Chicago Collaborative, which assisted on the project, reminded developers that tools such as OpenGrid are a first step. He pointed out that despite Chicago’s advances in open data, problems such as police misconduct have arguably gotten worse.
“There are no dots on a map that stopped that from happening,” O’Neil said. “There is no set of crime statistics that stopped that from happening. We have to find ways to have communion with people who are not here.”
North Side Chicago Neighborhoods Experiencing a Baby Boom
Increases in children have accounted for all of the populations gains in Lakeview and Lincoln Park since 2000, and nearly 60 percent for North Center.
While many may think of Chicago’s Lakeview neighborhood in terms of hordes of recent college grads roaming Wrigleyville, over the past 15 years the area has been adding children faster than almost any other area of Chicago.
According to figures from the Census’ 2010-2014 American Community Survey, Lakeview has added more than 3,000 children who are 17 years old or younger, the second-most among Chicago community areas. Right behind are neighbors Lincoln Park (to the south) and North Center (to the west).
Even with gains, though, children still make up a small percentage of the total residents in the three community areas.
The shift has attracted notice from businesses in the neighborhood. Last year the Lakeview Chamber of Commerce worked with the Center for Neighborhood Technology to study the change.
They found the number of households in the area was dropping, especially around transit stops, while population was holding steady.
“We found that despite loss of housing units, the population has been increasing, almost exclusively due to increase in children,” said Lee Crandell, executive director of the Lakeview Chamber. “We can definitely see that walking around. There’s lots of strollers.”
Soon we’ll be looking at some related trends, including how competition for public schools in those areas is starting to reshape the neighborhoods and who can live there. It’ll be interesting to see if this trend continues, and if those neighborhoods can support the number of families moving in.
A quick look at why there are more Chicago building permits this year
Construction in Chicago has made a comeback over the past few years. According to city data, since the bottom of the recession the city has seen a turnaround with more permits issued for new construction with the values of those permits growing.
Still, this recent press release from the Mayor’s Office caught my attention:
To date, the City has issued nearly 32,000 building permits, for projects throughout the City – including new home construction and renovation, new businesses, restaurants and large commercial and residential developments.
By the end of the year the City expects to issue nearly 1,000 more building permits than were issued in 2014, and reach the highest number of permits issued since 2008.
The information on the city data portal doesn’t exactly match up with those numbers, but it’s very close and it confirms the main message: Overall, building permits are up in Chicago year-over-year, and at their highest level since 2008.
Looking a little closer, though, the story isn’t quite as clear. Splitting out permits by type, the increase this year isn’t driven by renovation and new construction, but permits for electrical wiring (The city describes these permits as covering “major and minor electrical work both permanent and temporary”).
Permits for activity such as renovation and new construction are actually flat. Renovation and new construction are down but near last year’s levels, while demolitions have gone up slightly.
So yes, Chicago has had more building permits issued this year than last, but the activity isn’t exactly the picture painted by the release.
Chicago and Cook County ban discrimination against potential tenants solely because they pay their rent with Section 8 vouchers. But WBEZ found discriminatory listings on Craigslist are common, and often go unpunished.
Today we released a report looking at housing discrimination on Craigslist. To do the story we analyzed a month’s worth of housing ads mentioning Section 8 and vouchers in the Chicago area, more than 2,800 in all. We found more than 200 instances of landlords discriminating against voucher holders, but also thousands advertising directly to them.
The White House is investing in a data project to make Chicago a “smarter,” fitter city.
Can data predict how nonprofits should use their resources?
Watching the final projects from this summer’s class of Data Science for Social Good fellows, one theme became apparent.
Here are the goals from half of the dozen projects:
Predicting adverse birth outcomes
Predicting high school students who may not graduate on time
Predicting college persistence
Identifying restaurants most-likely to donate food
Predicting home abandonment in Mexico
Predictive enforcement of hazardous waste
And other projects looked at the probability a property would have a building code violation, which police officers were at risk of misconduct and identifying which donors nonprofits should target with emails.
Over the past three years of searching for problems data can solve for nonprofits and governments, the group has clearly coalesced around an idea: That predictive modeling can help those organizations better use their scarce resources.
The data suggest this could work. The team looking at adverse birth outcomes (babies born too small or premature) estimated their model works 1.5 times better than the Illinois Department of Health’s current method. The group helping the World Bank detect fraud said they could increase efficiency by 50 percent.
Whether that will be the case is yet to be seen. The fellowship is only in its third year, so data is still coming in, but the city of Chicago has seen gains in its own programs such as rodent detection and food inspections.
Not every project focused on prediction. One built a tool to track when interest groups introduced almost identical bills in different states, and another created a website that helps community colleges follow current job trends and direct students to in-demand industries.
Still, the main problem the fellowship wants to solve seems to be one that has followed civic organizations since their start. How do they do more with limited time and money? Data Science for Social Good doesn't have all the answers, but for some problems data can help them triage.
Code for America working to release Indianapolis police data
In May the White House launched its Police Data Initiative, a program looking to help departments release more data and also use that information to improve how they do things.
Over at WBEZ.org we spoke with a group in Chicago working with the Charlotte-Mecklenburg Police Department on the second problem, trying to improve their early intervention system to find officers at risk for misconduct.
In Indianapolis, a different organization is working with police there to try and open up the agency’s data on police interactions with citizens.
This year fellows from Code for America partnered with the White House and the Indianapolis Metropolitan Police Department to figure out how to release IMPD’s Internal Affairs data. In the process they created an Open Police Data Census, cataloguing what information is available from departments across the country.
This week we spoke with fellows Chris Reade and Laura Ellena about the project and what they’ve learned so far.
How did this project come together and how did you come to work with the White House?
Reade: The way Code for America works, is that we’re all experienced tech industry, city government folks. We get assigned to city that has a broad goal they’d like to have technology achieve. We got assigned to Indianapolis and their Public safety department.
They wanted to look at a bunch of different ways they’ve collected data in the process of doing their jobs and seeing what they could do with that data to help the department. Police departments collect a lot of information in the course of doing their jobs, and they think there is valuable uses for a lot of that in a law enforcement sense, but also in a community relations sense.
We were lucky and got invited to go with Indianapolis to the White House’s police data convening. They had brought together a whole bunch of different police chiefs from around the country to use data for a few specific ends. One is building trust in the community and the other was internal focused, how do we use the data we’re compiling to do our jobs better.
As a part of that meeting [Indianapolis] committed to releasing a pretty healthy set of data. We were really excited to be a part of that meeting, but also excited to be help them. We’ve been working with them since on a subset of the datasets to automate the release of that data and figure out what’s the best way to get that to the public and present it to the public and enable the public to use that in a way that furthers everyone’s goals.
When you first got started, what were those interactions like?
Reade: Everyone was really excited to have us there. There are a lot of ideas of that people have for all sorts of different uses that police data could be used for to further all kinds of different goals. So not just the community relations aspect. We went on a couple of ride alongs, we talked to a lot of the moving parts in the public safety department in how they use technology, collect data and are trying to make better use of it. There are a lot of moving parts in any public safety department. You have 15 different logins you’re trying to remember to get through your day. There’s a lot of technology in the field, and I think people are looking for a way to tie related datasets together.
What has the day to day been like for you?
Reade: We’ve been doing a lot of reaching out to anyone who would be interested in using this data external to the public safety department. We’ve been talking to neighborhood groups, researching institutions in Indianapolis, more activist focused groups. We’ve been trying to collect what people are looking for from this police accountability data, and then the technical aspects of releasing this. We’re lucky in that most of the information that we’re focused on releasing is in one application, so extracting the information from that system is a privacy-focused way that is then useful to the people outside the police department are interested in seeing that information
What datasets are you looking to release?
Reade: Indianapolis like many cities has a couple of ways of viewing crime data. When you talk to people about police data, often the first thing they come up with, is what the actual crime information is. Indianapolis is already pretty good about that. We’re focused on officer involved shootings, use of
force, and citizen complaints.
What have you been hearing from groups about what they’d like to see released?
Ellena: Location is really important to people; everyone is curious what is happening in their neighborhood to give some context to the data. Both department of public safety and community groups are interested in educating residents on how to have better interactions with the police, so thinking about how to provide that context next to the data.
Having worked through this a little bit, what are your goals for when the fellowship ends (Nov. 15)?
Reade: What we’re looking at now is a way of extracting information from the internal affairs application, scrubbing that information of any identifying information, anonymizing the location data, and then summarizing it in a way that meets the needs of the community, and then provides enough context to understand what the numbers actually mean and what the department is doing to change those numbers on a publicly-available website.
Ellena: We want to satisfy the data nerds who want to download the whole dataset and play with it, but also give your average resident a summary website that lets them to see what’s going on without getting too technical.
Reade: One other initiative we’re working on, before we dove into this we wanted to see what other departments were doing, so we put together a police open data census to see what other departments are doing. Who’s releasing this, in what format and how much context they provide.
Ellena: This is so new, there are no best practices yet for police departments, so we built that partially for ourselves to be able to make recommendations in Indianapolis, but also for anyone else who is interested in police data and other cities who may want to release things on their own.
What sort of things were available when you started looking?
Reade: The big thing we focused on was use of force and officer involved shootings, and there are a couple of departments who have really pushed ahead. Dallas comes to mind, Philadelphia, Denver and the district attorney’s office, they release really detailed narratives on every incident.
A lot of departments do release this information, but not in the open data way we approach things. Many departments will release an internal affairs report every year that has all of their complaint data and often a lot of use of force information. Unfortunately, they’re often in PDFs squirreled away deep in the departments website. I don’t think that’s necessarily on purpose. A lot of departments that have concerns about this don’t realize they’re already publishing something very similar that might be better served on a website than in a PDF document.
Was there anything that surprised when you saw what departments made available?
Reade: The depth that some departments are comfortable going into real incident-level descriptions was something we were a little surprised by given that it is new and pretty sensitive for everyone involved. What we’ve heard, some groups really do have a desire for that level of detail.
Where there any major data needs?
Reade: The incident level information is pretty varied. Most places don’t get into the incident level information. And there isn’t a trend in the size of the department and their willingness to do it. A lot of big cities are in it, a lot of small cities are in it, there are a lot of big cities that don’t seem to release this information online. Which doesn’t mean they aren’t releasing it, I just means that it might not be within our Googling skills.
Ellena: It sounds like a lot of departments are in the process of making the transition from tracking these things on papers. If they don’t have an internal affairs system, it’s likely that this information is in file cabinets rather than a database.
What do you see happening if all this data was out there? How would it improve policing?
Reade: One of the big ones is just demonstrating the police department's willingness to be transparent, to be open to community oversight and recognize that they are servants of the people and people deserve to have the information they need to provide that oversight.
We also think that grounding the conversation in something tangible is beneficial. Having real numbers and trends to point at will help people to have a better conversation about policing in the community.
Ellena: With the community and internal, too, maybe you can identify if there are reasons you respond to a call or times and days that these incidents that go poorly have in common, and can we use that information to make things better.
Remembering one of Chicago’s contributions to data visualization history: The Catrographatron
A map produced by a Cartogrphatron for the 1959 Chicago Area transportation Study
Today, plotting thousands of points on a map isn’t the hardest thing to pull off. With the right tools, journalists and other would-be cartographers can do it with a few clicks, but in 1959 the task was so onerous that it forced a group of Chicago researchers to invent an entirely new way of doing it, one that 21st century geography nerds still reference.
Enter: the Cartographatron.
Moving people around Chicago has always been an issue, even back in the 1950s. In 1956 the Chicago area was home to 5.2 million people and, with their 1.46 million cars, they collectively made 10 million one-way trips each weekday. With the region constantly growing, the city, Cook County and the state of Illinois commissioned the Chicago Area Transportation Study to look at how people travelled the area and try to figure out how it was changing.
Among other things, researchers wanted to look at desire lines, or where people started and stopped their trips. They had survey data, but how to visualize these lines?
To trace a line from the point of origin to the point of destination, for every trip occurring in an urban area on an average day, is impractical. Further, if such a map were drafted, it most certainly would not be legible.
At the time, the most common ways to map trips was to either group them into zones and draw lines of different width connecting them, or to create a grid and then have a machine trace the trips. The machines would receive instructions from punch cards.
Neither of those worked for the CATS, so the group contracted with the Armour Research Foundation of Chicago to create an entirely new machine to make maps: the Cartographatron.
The Catrographatron was the size of a large desk, described by the study as “a combination of an electronic computer, a television picture tube, and a camera.” Trip information was encoded on punch cards and then transferred to magnetic tape. The information on tape would be used to generate a blip of light on a cathode ray tube in the shape of a trip line. The Catrographatron’s camera would then record that light on a continuously exposed negative.
The CATS report lays out the technique, which allowed the researchers to show trip data at a much finer scale and faster than any other method available at the time.
Trip records from all surveys combined require more than 378,000 punched cards. In terms of magnetic tape, this equals nineteen reels. This is the travel inventory file which, when expanded, accounts for each of the 10,500,000 daily trips. Allowing time for the changing of reels, it takes about 7 minutes to run one reel. A map of the entire file can be prepared in approximately four hours.
The resulting image showed land in black, with increasingly bright rays of light emanating from Chicago, visualizing the movements of millions of people into and out of the city each day.
The Catrographatron was innovative enough for the time to get a writeup in Popular Mechanics, alongside an early prototype for a space suit and a welding gun that could be used in space.
While there aren’t many other example of Cartographatron use outside of the CATS, its contribution to data visualization is still felt today. It was one of the first computer models of urban data, and it recently inspired a series of traffic maps for the San Francisco Bay Area from Alasdair Rae of the University of Sheffield. That series has been shared all over the web. (We originally found the CATS paper there, too. Thanks Alasdair!).
While there’s so much great work and thought around data visualization today, sometimes its good to look back and remember that we all owe a debt to the designers who came before us.
A cop’s view of Chicago’s tangled neighborhood boundaries
Chicagoans love to cut the city into neighborhoods a million different ways. Sociologists have their 77 community areas, aldermen 50 wards, and realtors can tell you all about more than 200 unofficial neighborhoods (and why you should get your next apartment there).
How often, though, do you get to hear the perspective of a group of people who walk the streets all day — police officers?
One cop stepped up and wrote about it in 2012. We noticed it recently when Chicago Tribune reporter Peter Nickeas shared the paper, by CPD Captain Marc S. Buslik.
Buslik explains what cops think about when they define a neighborhood. For an officer, a place is part of a neighborhood as well as one of the shifting, informal definitions we give it as residents. It’s also a block, a district, or a beat — but police also view a neighborhood “through the rubric of routine activity theory, in which the victim and offender converge in time and place.”
They have to combine all of those definitions into something that can help them deploy resources and try to improve public safety. It’s a big task, and one he admits is often difficult and must constantly be redone as boundaries and networks shift.
In the paper Buslik points out that while cops see the city in a way that’s unique to them, they still have to deal with the boundaries the rest of us create, too. Case in point:
Police districts and wards criss-cross each other so that one district commander may work with multiple aldermen, or an alderman may work with multiple district commanders, to serve the needs of citizens. As with districts, wards provide no better sense of serviceable neighborhoods. The final account of these overlapping boundaries is a map that shows the difficulty the police have when defining neighborhoods to apply crime prevention services and deploy patrol resources.
That district commanders work with multiple aldermen isn’t a revelation. With 50 wards and 22 districts, all commanders will work with at least two aldermen. But exactly how many aldermen do commanders work with?
On average, each Chicago police district overlaps six individual wards, with some (the 9th, 19th, 25th) crossing as many as nine. For example, the 19th District takes in part of wards 1, 2, 32, 33, 40, 43, 44, 46, 47:
Want to know your district and ward? Check out our full map and put in your address.
In some cases there are only a few blocks of a ward in a district, but if there was a major crime issue in those few blocks, you can be sure the commander would hear from the alderman. Overall, there are 132 different combinations of ward and police district, depending on where you live in Chicago.
Last year we attempted to quantify how gerrymandered Chicago wards are, and looked back at the history of how Chicago’s main political boundaries were formed. In this last redistricting cycle following the 2010 census, it was no secret that the main driver behind the new boundaries wasn’t creating an efficient city.
Chicago’s Million Dollar blocks tracks where money is spent on prison sentences
There are more than 800 city blocks in Chicago where the state of Illinois will spend more than $1 million incarcerating the people who live there, according to a new project from Adler University researchers and Chicago's DataMade.
Chicago's Million Dollar Blocks maps where Illinois will spend the most keeping residents of those areas in prison over the life of their sentences.
Not surprisingly, the hardest-hit areas are on the city's West and South sides. The state will spend $550 million to lock up just the residents of the Austin community area, according to the study.
The project builds off of work from the Justice Mapping Center and Cook County Circuit Court data released by the Chicago Justice Project.
Using conviction data from 2005-09, the team took an average cost per inmate of $22,000 a year and applied that to the minimum term for each sentence to come up with a total cost per block (read more in the project’s methodology section and the github repo).
Dan Cooper, Co-Executive Director of the Institute of Social Exclusion at Adler University, said even those estimates could be small.
"We think we have a pretty solid estimate," Cooper said Tuesday at Chi Hack Night, formerly known as Open Gov Hack Night. "[But] this is actually pretty conservative."
While the big-picture numbers are surprising, there are also a number of smaller insights hidden in the map.
The block with the highest spending amount is actually home to Jones College Prep High School in the South Loop. Cathy Deng, a developer with DataMade, said a former homeless shelter in the block (it closed in 2007) was the single most-used location in the dataset.
The state of Illinois will spend more than $30 million incarcerating prisoners who provided the homeless shelter as their address over the course of their sentences.
Cooper said the hope is that the project continues momentum for prison reform, shifting a focus from incarceration to supporting a more cross-discipline approach, and not just for low-level crimes.
"We really honed in on this message that there's a danger in only focusing on low-hanging fruit," Cooper said. "The problem is that the evidence base that incarceration is successful rehabilitation is pretty thin. The bar is set pretty low, but we're holding this to a pretty high standard."
Illinois has taken some steps around prison reform, including the Redeploy Illinois program and a task force started by Gov. Bruce Rauner.
"We really don't see any reason Illinois can't be a leader in this and that the president won't be in Illinois talking about how much we've saved not incarcerating people," Cooper said.
Local governments produce information that is most relevant to voters. Shouldn’t local officials have the best tools to share it? A civic engagement toolkit, designed with local election officials, helps officials identify how to use communication tools, and provide measurable ways to ensure they are responsive to the needs of their communities. The toolkit is a series of checklists, along with examples and templates for: -Icons & illustrations -Community surveys, both online & offline -Communicating in plain language -Resource allocation & wait time calculators -Coordinating efforts with Election Assistance Commission, state gov offices, the media, and projects like Rock the Vote and the Voting Information Project -Outreach tools
Cook County — specifically Clerk David Orr and Director of Elections Noah Praetz — are part of a team that won a Knight News Challenge grant to create a toolkit for local election officials to create more engaging materials for voters. They’ll be working with members of the Center for Technology and Civic Life and the Center for Civic Design.
The Chicago Department of Public Health has more than 15,000 establishments to inspect and only 38 inspectors to do it. So how do they make the most of their resources? The department has a brand new
WBEZ and Catalyst Chicago bring a first-ever analysis of graduation rates for every public high school in the city. Half of all high schools hold on to less than 50 percent of the students who walk through the doors as freshmen.
This week we posted a look at how many CPS students actually graduate from the high school they started at as freshmen. Within that is a discussion of how the district reports graduation rates, and the different methods can change the final figure.
As part of the story we posted all the data behind the investigation, showing the graduation rates and raw number of graduates at CPS schools. Download the data and find out where students in your area actually end up graduating.
Chicago’s run-off election is just weeks away. What if there were an app to tell you how long you would have to wait in line at your polling place? Or another one that could tell you exactly when your vote was counted? Those are a couple of possibilities for having more open data on elections. The Sunlight Foundation is starting a series looking at what election data is already available and what’s missing. Its director of partnerships and training Amy Ngai, joins the conversation.
