Dallas 311 Service Requests from October 2020

Dallas Open Data provides records of non-emergency service requests reported by citizens since October 1, 2020. The dataset includes over 400 request types, such as animal services, code compliance, and street repair. It is maintained by the City of Dallas and was last updated in April 2026.

Use Cases

• Predict `ERT (Estimated Response Time)` based on `Service Request Type`, `Priority`, and `Department` using regression models.
• Analyze spatial patterns of requests like 'high weeds' or 'pothole repair' using the `Lat_Long Location` and `City Council District` columns.
• Model the `Status` or `Outcome` of requests as a classification task using features like `Method Received Description` and `Created Date`.
• Perform time-series analysis on request volumes by `Service Request Type` using the `Created Date` field to identify seasonal trends.

Strengths

• Covers a multi-year period from October 2020 to present, enabling longitudinal analysis.
• Includes a diverse set of over 400 distinct `Service Request Type` categories.
• Contains precise geospatial coordinates via the `Lat_Long Location` column for mapping.

Limitations

• The total number of rows is unknown, making it difficult to assess dataset scale.
• Data completeness for fields like `Closed Date` or `Outcome` is not verified.
• Potential geographic bias, as data is limited to the City of Dallas jurisdiction.
