U.S. Behavioral Risk Factor Surveillance System Data 2015-2022

United States data from the Behavioral Risk Factor Surveillance System (BRFSS) covers topics related to Alzheimer's disease and healthy aging from 2015 to 2022. The dataset includes survey responses aggregated by state and county, with columns for specific questions, data values, confidence limits, and stratification categories. The data is maintained by public health authorities and was last updated in February 2025.

Use Cases

• Analyzing geographic disparities in health indicators like obesity or cognitive health using the `LocationDesc`, `States`, and `Data_Value` columns.
• Examining trends over time for topics such as vaccinations or screenings by combining the `YearEnd` and `Topic` columns.
• Comparing demographic stratifications for health behaviors like smoking or alcohol use via the `StratificationCategory1` and `Stratification2` columns.
• Mapping public health metrics for specific counties or states using the `Geolocation` and `Counties` fields.

Strengths

• Contains detailed survey question and response data across 8 years (2015-2022).
• Provides granular geographic breakdowns with state and county-level identifiers (`LocationID`, `States`, `Counties`).
• Includes statistical confidence intervals (`Low_Confidence_Limit`, `High_Confidence_Limit`) for many data points.

Limitations

• The exact row count and total dataset size are unspecified across all platforms.
• Potential staleness exists as the core data range ends in 2022, despite metadata updates in 2025.
• Geographic coverage is limited to the United States, which may introduce bias for global analyses.
