SMART MMSA: Behavioral Risk Factor Survey Data for Metropolitan Areas (2011-Present)

2011 to present. The dataset contains prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) for selected Metropolitan Statistical Areas (MMSAs) with 500 or more respondents. It is produced by the Centers for Disease Control and Prevention (CDC) and is updated annually to track modifiable risk factors for chronic diseases and leading causes of death.

Use Cases

• Analyzing trends in health risk prevalence over time using Year, Topic, and Data_value columns.
• Comparing health indicators across different demographic segments using Break_Out, Break_Out_Category, and Locationdesc columns.
• Estimating confidence intervals for survey estimates using Confidence_limit_Low and Confidence_limit_High with Sample_Size.
• Mapping health metrics for metropolitan areas using GeoLocation (city) and GeoLocation (state) columns.

Strengths

• Data is updated annually, with the last update recorded on 2025-02-19 16:24:54.
• Includes confidence intervals (Confidence_limit_Low, Confidence_limit_High) for statistical reliability assessment.
• Covers a long temporal range from 2011 to the present.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• License information is not provided in the input metadata.
