The data for this metric is from the Behavioral Risk Factor Surveillance Survey (BRFSS) and estimates the female population aged 18 and older who would respond that they experienced at least 14 mentally unhealthy days within the past 30 days at the time of response. The statistic divides those estimates by the BRFSS estimates for the total female population 18 and older. Note: source does not provide data for all geographic locations, such as in cases where data collection is low.
