Map of Reported Bullying Incidents
The map below displays the total number of bullying incidents by district over the specified time frame. Use the inputs on the left to filter to a specific type of incident and/or a specific year. Districts colored in white had missing or redacted data during the specified time frame.
Modeling the Trend
Here we use a Simple Linear Regression to model the trend in bullying incidents between 2013 and 2016. A negative trend (colored in green) indicates that bullying incidents appear to be on the decrease, while a positive trend (colored in red) indicates an increase. Districts are colored white where data was redacted or too limited to compute the model.
This data was collected by the Iowa Department of Education
. The data has been collectd from the Excel spreadsheets on the site. Because of a change in data format in 2013, data from prior to 2013 was not used. Also note that in districts where bullying incidents were between 1 and 9 in a particular year, the exact value was redacted to preserve student privacy. We have set these values to be missing, and thus districts with these redacted values will appear as white on the maps.
