About
Provides historic data related to 911 emergency calls, documenting instances where the public required assistance from police or emergency services. This information allows for analysis of public safety responses, showing where and why calls were made. The purpose of this data is to help understand the patterns and contexts of emergency events, reaffirming the role of emergency services in enabling the public to live without fear.
Columns
- lat: The recorded latitude of the location from which the call originated.
- lng: The recorded longitude of the location from which the call originated.
- desc: A small description detailing the place of the call.
- zip: The five-digit postal code associated with the call location. Note that approximately 13% of records are missing this detail.
- title: Specifies the reason the emergency call was placed (e.g., Traffic: VEHICLE ACCIDENT, Traffic: DISABLED VEHICLE).
- timeStamp: The exact date and time when the call was logged.
- twp: Identifies the station or township that received or handled the call. Lower Merion and Abington are among the most frequently listed stations.
- addr: The street address associated with the call.
- e: An indicator variable, typically showing if the call was attended to.
Distribution
The dataset is typically provided in a tabular format, such as a CSV file (e.g., 911.csv), with a size of approximately 18.38 MB. It consists of 9 distinct columns and contains close to 99,500 valid records or rows. Data quality is generally high across most fields, though there are noted missing values in the zip code and address fields.
Usage
This dataset is ideal for several analytical applications, including:
- Data Visualization: Mapping the geographic distribution of calls, identifying hot spots, and visualising trends over time.
- Classification: Developing models to classify call urgency or predicting the type of incident based on location and time.
- Public Safety Analysis: Studying response times, call volume peaks, and resource allocation efficiency within specific townships.
- Educational Projects: Serving as a real-world example for studying spatial-temporal data and emergency response systems.
Coverage
The data covers a time span ranging from December 2015 through to August 2016. Geographically, the records are concentrated in an area defined by latitude ranges between 39.54 and 41.17 and longitude ranges primarily focused around -75. The dataset includes specific references to townships such as Lower Merion and Abington, providing focused insight into the historical activities of these regions during the specified period.
