To start off, I believe the positive aspect about this hate crime dataset is that it provides trends that happened over the time of seven years such as New York which we’re able to see if incidents goes up and down over time. In addition, this data involves various bias locations and possibly had responses from the police force or other government force that made it possible to have comparative and spatial analysis. On the negative aspect, there were some limitations that I found, there were many crimes that weren’t all reported or misclassfied so the data may not be as accurate as the true number of incidents there were. Not only that but there’s also a high chance of inconsistent recorded crimes in different jurisdictions which includes privacy concerns and/or missing categories/areas of data that could affect analyses.
The two different paths I would like to (hypothetically) study about this hate crime dataset is one a spatial temporal analysis to pinpoint hot spots for hate crimes in New York City. Then to observe and track the changes over time, potentially link them to demographic shifts. The second study I would is examine whether spikes in hate crime incidents have something to do with major political or social events such as (presidential elections, announcements about immigration policy, serious crimes, or court decisions that includes minority groups).
