Crime Throughout the Year in Broward County, Florida
the Year in Broward
Group X: Chin-Wen Chang, Andrew Lee,
Arpita Shah, Jenna Schoen
- Interested in crime rates and various time variables
- Do crime rates vary seasonally?
- Do certain days of the year have spikes or dips in crime?
- Are more crimes committed on the weekends?
- Might the weather affect criminal activity?
- Are certain types of crime correlated with any of these
- Base dataset: “compas-scores-two-years” from ProPublica’s
- Restricted dataset to arrests in 2013 and 2014, and only used the
first arrest (not recidivist or violent recidivist offenses)
- Selected 5 of the most common types of crime (Drugs, Burglary,
Grand Theft Auto, Battery, DUI) and manually grouped them
(covered 55% of crimes)
- Incorporated daily average temperature and precipitation for
Broward County, FL, 2013-2014 (from the National Centers for
Conclusions and Considerations
- Need bigger data set to make more significant correlations (e.g. longer range of time, more counties in or
outside of Florida)
- Probably more difficult to find correlation between weather and crime in tropical rather than temperate
- Worth keeping in mind that these are arrests, so police presence may play role in these correlations as well
(e.g. if less police are on duty on Sunday or Christmas)
- We can confidently conclude that in Broward County from 2013-2014:
- Crime most frequent on Fridays and least frequent on Sundays; battery and DUI diverge from this
pattern (frequent on Saturday and Sunday)
- Dip in crime on Halloween and Christmas, spike in crime on Thanksgiving
- Burglary not common when raining
- Battery and drug crimes oddly seem to be more frequent in colder weather
- Further questions:
- Would we see different data in a different county prone to different types of crime?
- Would we see different data in a different county with different weather and popular holidays?
