Precog Crime Prediction for London


A new interactive map claims to be able to predict the number of crimes that will be committed in London neighborhoods in 2017. Dataiku's London Crime Prediction Map 2017 shows the predicted number of crimes and whether the number of crimes is expected to rise or fall in 2017 in each London neighborhood.

The circles on the map represent the predicted number of crimes in each Lower Layer Super Output Area (LSOA). The size of the circles represent the number of crimes and the color shows the percentage change in the number of crimes compared to 2016. You can click on a neighborhood's circle to view the number of predicted crimes in the area for each month in 2017.

You can learn more about how Dataiku built their predictive model for London crime in their Predicting London Crime Rates Using Machine Learning article. A very basic summary of the model is that it uses historic London crime data, census data, information about the number of points of interests in an area (such as shops and pubs) and the location of police stations.
