The Behavioral Risk Factor Surveillance System (BRFSS) is classified as a secondary data source. This distinction comes from the fact that secondary data involves the collection of information for purposes other than the current study being conducted. The BRFSS collects data from a multitude of respondents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services, which are then made available for various analyses by researchers and public health officials.

By utilizing existing data collected by BRFSS rather than gathering new, original data directly, researchers can analyze patterns, trends, and associations related to public health issues without the time and resource implications of conducting original surveys. This allows for broader and more comprehensive insights into health behaviors over large populations. This foundational understanding underscores its classification as secondary data, in contrast to primary data, which would entail the fresh collection of information directly from participants.
