North Carolina Crime Dataset

Dataset Description

Dataset Summary

The dataset, derived from public police incident reports from various cities in North Carolina, spans from the early 2000s to 2024. The source data originate from the open data portals of Cary, Charlotte, Durham, and Raleigh. The dataset underwent a process of merging data from these cities, followed by cleaning to remove incomplete rows. Additionally, the dataset focuses on extracting and categorizing major crime types, providing valuable information such as crime type, time, location of occurrence, and other relevant details.

Supported Tasks

  1. Crime Trend Analysis: Analyzing crime trends over time and across different locations. This could involve identifying patterns in crime rates, seasonal variations, or shifts in the types of crimes committed.

  2. Predictive Policing: Developing models to predict future crime occurrences based on historical data. This could help in resource allocation and proactive policing strategies.

  3. Geospatial Analysis: Mapping crime incidents to identify hotspots and regions with higher crime rates. This can aid in understanding geographical factors influencing crime and in deploying resources more effectively.

  4. Crime Type Classification: Using machine learning algorithms to automatically classify incidents into different crime types based on the incident descriptions.

  5. Time Series Analysis: Examining how crime rates change over time and understanding long-term trends or cyclic patterns.

Dataset Structure

Data Instances

Here is an illustrative example from the processed dataset (note that specific details are subject to change):

{
  "year": 2022,
  "city": "Raleigh",
  "crime_major_category": "Theft",
  "crime_specific_category": "Vehicle Theft",
  "latitude": 35.7796,
  "longitude": -78.6382,
  "start_time": "2022-05-15T14:00:00",
  "end_time": "2022-05-15T16:00:00",
  "clear_status": "Cleared by Arrest",
  "incident_address": "123 Main St, Raleigh, NC",
  "notes": "Weapon: None"
}

Data Fields

The dataset contains several fields, each providing specific information about police incidents. Here is a list of these fields along with their descriptions and data types:

  • year (integer): The year in which the incident occurred. Used as input in temporal analysis tasks.
  • city (string): The city where the incident took place. This field is crucial for geographic analyses and comparisons between cities.
  • crime_major_category (string): A broad categorization of the crime, used as input for crime pattern analysis and categorization tasks.
  • crime_specific_category (string): More detailed classification of the crime, falling under the major category. This field allows for a finer-grained analysis of crime types.
  • latitude (float) and longitude (float): Geographical coordinates pinpointing the location of the incident. These fields are essential for geospatial analysis.
  • start_time (datetime) and end_time (datetime): The beginning and end times of the incident, providing temporal context. These fields are used in analyses that require time-based information.
  • clear_status (string): The resolution status of the case, such as whether it was cleared by arrest or remains under investigation. This field can be used to understand case outcomes.
  • incident_address (string): The specific address where the incident occurred. This field adds a detailed spatial dimension to the data.
  • notes (string): Additional remarks or details about the incident, like weapon usage or other relevant factors. This field provides supplementary information that may be relevant for certain analyses.

Dataset Creation

Curation Rationale

The dataset, covering police incidents in select North Carolina cities from 2000 to 2024, aims to aid crime research. It provides a long-term view of crime patterns and trends, useful for criminologists, sociologists, and public policy researchers. The comprehensive data enables analyses of crime evolution and its socio-economic correlations. It also supports the development of predictive models for law enforcement and policy planning. Additionally, the dataset's multi-city scope allows for comparative studies to understand unique challenges and inform localized crime prevention strategies.
