Behavioral Risk Factors: Selected Metropolitan Area Risk Trends (SMART) MMSA Age-adjusted

2011 to present. Age-adjusted prevalence data from the Behavioral Risk Factor Surveillance System (BRFSS) for selected U.S. metropolitan statistical areas (MMSAs) with 500 or more respondents. The data is collected by the CDC through a continuous, state-based surveillance system tracking modifiable risk factors for chronic diseases. It is updated annually and hosted on data.cdc.gov.

Use Cases

• Analyzing trends in health risk prevalence over time using Year, Data_value, and Confidence_limit_High/Low.
• Comparing behavioral risk factors across metropolitan areas using Locationdesc, Topic, and Break_Out.
• Assessing statistical reliability of prevalence estimates for specific questions using Sample_Size and Data_Value_Footnote.
• Mapping health indicator estimates by metropolitan area using Geolocation (address) and Data_value.

Strengths

• Time series data from 2011 to present, updated annually.
• Includes statistical confidence intervals (Confidence_limit_High, Confidence_limit_Low) and sample sizes (Sample_Size) for reliability assessment.
• Covers multiple health topics and demographic breakouts via Topic, Break_Out, and BreakOutCategoryID columns.

Limitations

• Row count and total dataset size are unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
