As part of a class project, we sought to analyze the Boston crime dataset to identify trends and patterns from 2015 to 2024 through (1) Data visualization and (2) Data analysis. Our objectives included examining the distribution of incidents across different districts, the timing of incidents by day, month, and year, and specific types of offenses like harassment and property loss. By addressing data quality issues, managing a large and complex dataset, conducting temporal and geographical analysis, and formulating resource allocation and policy recommendations, we aimed to provide insights that could contribute to proactive crime prevention efforts and improve community safety.

What I did

• Analyzed the Boston crime dataset (2015-2024) to identify trends and patterns across districts, timing of incidents, and specific offenses, aiming to leverage data-driven insights for crime prevention and community safety improvement.
• Inspected and cleaned the dataset, including merging separated data, handling missing values, and converting data formats. Addressed inconsistencies, such as multiple values in the 'SHOOTING' column, and removed unnecessary columns.
• Visualized crime distribution by district, time, and offense type. Identified districts with high crime rates (B2, A1, B3, D4), observed seasonal and monthly trends, and noted shifts in crime patterns pre-, during, and post-COVID-19.
• High crime rates were found in specific districts with seasonal and monthly variations. Recommendations included resource prioritization in high-crime areas, targeted interventions during identified peak times, and exploring the impact of public health measures on crime rates. Future work suggested examining additional datasets to understand the influence of other factors on crime dynamics.
