I asked a data analyst at the Bureau of Justice Statistics who provided this answer:
"I would say that the answer really depends on what information they are trying to show. There are many different way to normalize crime data and even multiple different ways of doing population based rates.
For example, I've even seen some people playing around with ...
There is tons of data at the US Bureau of Justice Statistcs - Corrections
But I think the best way is to get these data points from the two major private prison companies (CCA and GEO Group).
Luckily (for you), both are publicly traded - so you can download their annual reports and find all sorts of info about number of beds, and different types of housing....
The Open Knowledge Foundation keeps a list of Cities that publish crime datasets. Most datasets have location data. In some cases the location is in State Plane coordinates instead of Lat/Lon. They list 51 cities.
Below is a blog posting I posted a year ago on methods for doing crime analysis:
There are quite a few cities that publish this data. A quick way to find it, is via Data.gov, which provides local government as well as federal government data. There are 53 city crime statistics datasets published, most of which include location data:
All 53 city crime datasets, which are from 9 cities, but broken down by multiple factors for better ...
The FBI collects common Uniform Crime Reporting (UCR) data from all municipalities. These include things like murder, rape, assaults, property crimes, vehicle theft etc. Their primary site is here: http://www.fbi.gov/about-us/cjis/ucr/ucr and they have common stats going back decades.
Typically, municipalities use a /1000 population rate which can also be ...
I can throw in 2 cents on this subject. First, I would not use population of a point-of-interest as the sole normalizer in a crime analysis. Crime is more tied to the combination of population, economic activity and social factors at both the POI and surrounding area. Below are examples of some of the factors in developing an algorithm:
The population of ...
After asking, I found via Googling a series from the National Archive of Criminal Justice Data (NACJD) called the Law Enforcement Agency Identifiers Crosswalk.
Here is its description from the NACJD website:
The crosswalk file is designed to provide geographic and other identification information for each record included in either the Federal Bureau of ...
For Europe you can find historical data in this database:
not with lat lon but rather NUTS-3 regions. you can obtain coordinates for the regions using geopy
For your first request, I would guess that the FBI's Crime Statistics would be your best source:
lots of great data, but not necessarily neatly divided into geographical units.
As far as convicted felons who have completed their sentences, I would guess that any data you can get on this topic would be extremely ...
As suggested, it really depends on what you're trying to do with these data. While there is strength in normalizing by pops, by transitional populations (more assumptions created here) those approaches meet certain needs. Providing bare counts is helpful but y'all seem to do that in Chicago already.
For a lot of our violence prevention work and for ...
I'm a bit confused about the problem you're ultimately trying to solve, because you mention maps but then indicate a desire to convert "counts" into rates. In any case, your primary question is
How would you normalize crime reports?
to which I would answer DON'T (whether you mean normalizing the source data before generating reports or maps, or whether ...
The City of Philadelphia makes Part 1 Crime Incidents available as a bulk download and via an API (ESRI ArcGIS online):
The data includes the lat/lon of the crime incident.
These blog posts by master Windows programmer Charles Petzold contain a few tables by country, and list a few other sources, notably the FBI.
The analyses are brilliant - they look effortless and to-the-point.
There are numerous instances of GIS crime data available to the public, at least in the US, probably too many list and/or no one has done an entire audit of the Criminal Justice open data space.
The overwhelming majority of these datasets are at the local level, on the locality's gov site and/or the locality's criminal justice agency's site (if they aren't ...
nibrs has department-reported events
ncvs is a complex sample survey
The Indian Government provides year-wise statistics on the number of people who are in prison and percentage of prison population by sentence length. So you could calculate the population which has completed its sentences. The data is available from: http://www.ncrb.gov.in/prisonstatisticarchieve/Main.htm
The FBI Crime Statistics/UCR data contains what you are looking for. They go back to at least 2005 (online). I think you will find what you want in Table 5, but there's lots to choice from:
The City of Oakland tacitly agreed to make the shotspotter data open, and the firm representative was eager to do so, but they've not followed up by doing so.
They did release it in bulk in Washington however, not real time.
Assumption: you are interested in United States data. This is all I really know about, sorry.
Unfortunately, I don't think you are going to find raw/disaggregated data at a national level. You probably already know about the aggregated FBI UCR datasets.
I think what you are looking for is what the public safety ecosystem calls "Incident" from a system ...
NYC publishes incident-level data in a similar way as Chicago (but only for felonies, it seems) at https://data.cityofnewyork.us/Public-Safety/NYPD-7-Major-Felony-Incidents/hyij-8hr7
NYC also has https://compstat.nypdonline.org/2e5c3f4b-85c1-4635-83c6-22b27fe7c75c/view/89 which while there is no "download the data" button, if you click on one of the numbers ...
The Uniform Crime Report program will have the best answer to your question for the U.S. The best known part of this program is the annual report "Crime in the United States" issued by the FBI every fall. That's the source of most of your crime rate information reported in the popular press.
What you're looking for is the clearance rate -- which is not ...
In this answer, I'm talking about regional crime statistics only (and I'm gathering materials for more relevant answer). In short, Ukrainian regional prosecutor's offices publish some criminal statistics on their websites.
You could be interested in the so called «Форма №1» (Form #1), which is also known as «Єдиний звіт про кримінальні правопорушення» (...
API (clean data)
It's available at the Crime Data API end point, you have to first request a data.gov api key then you can access it on
This is documented on the GitHub project crime-data-api, and the official Crime Data API page.
On Dec 20, 2018, the result of the API call is 7.7MB ...
It's important to remember that police jurisdictions generally follow administrative boundaries (in fact it's probably always this way). A city police force will only have jurisdiction within the city limits. What you're looking for is a dataset of administrative boundaries. Generally speaking, the Office of Management and Budget, the agency responsible for ...
I have not seen one worldwide comprehensive source. Instead, I think you will need to find it per country. Typically, this information will be published by the country's National Judicial System or National Statistics Dept. The US Department of State does publish 'summary' statistics on other countries. Here is the home page for crime and safety reports per ...
Besides NIBRS, there are many other open source data form provide county wide statistics, e.g., http://www.city-data.com/crime/crime-Durham-North-Carolina.html
Many cities also provide their crime statistics with frequent updates. For example, Durham Police Department provide interactive maps: http://gisweb.durhamnc.gov/gis_apps/crimedata/dsp_entryform.cfm
I believe you are looking for the National Incident-Based Reporting System (NIBRS).
As the name suggests, the unit of analysis is the incident itself. It offers many different types of data. Data based on the arestee, the victim (if any), the incident.
I am pretty sure it offers FIPS state-county codes too.
