Follow Up - What else could be explored?
The New York State hate crimes dataset combined with NY population data offers valuable insights but also presents limitations. The dataset provides detailed, incident-level insights into hate crimes across New York State, enabling targeted analysis of bias (hate) types, geographic patterns, and number of offences. However, the data suffers from voluntary response bias because reporting by law enforcement agencies is not mandatory, which leads to non-response bias and potential sampling error. Communities with limited trust in police or under-resourced departments may underreport, skewing the dataset. Additionally, information bias may arise from misclassification of incidents or inconsistent definitions of hate crimes across jurisdictions.
One research path is to study clustering of hate crimes around specific events. This could reveal reactive patterns tied to sociopolitical triggers. A second research path is to analyze law enforcement response disparities: comparing arrest rates, charges filed, and conviction outcomes across counties with similar population profiles. This could expose systemic differences in prosecutorial rigor or judicial outcomes. Both paths require careful attention to non-representative sampling and convenience bias.
