Behavioral Risk Factor Prevalence Survey Data from 2011 Onward

BRFSS combined landline and cell phone prevalence data provides state-level surveillance of modifiable risk factors for chronic diseases and leading causes of death. The dataset is updated annually and covers a time range from 2011 to the present. It is collected by the U.S. Department of Health & Human Services as part of a continuous, state-based surveillance system.

Use Cases

• Analyze trends in modifiable risk factors across states using the state-based surveillance data from 2011 onward.
• Study correlations between behavioral factors and chronic disease prevalence identified in the survey.
• Model public health outcomes based on risk factor data collected via combined landline and cell phone methodology.

Strengths

• Data collection spans from 2011 to the present, providing over a decade of longitudinal public health surveillance.
• The dataset is part of a continuous, state-based surveillance system ensuring regular updates and coverage.
• Detailed methodology and quality assurance documentation is provided by the CDC BRFSS program.

Limitations

• The specific number of rows, columns, and sample size is unknown, limiting precise assessment of dataset scale.
• Data is self-reported through surveys, which may introduce recall bias or measurement error.
• Annual update cycle means the most recent data may lag behind current conditions by several months.
