This statistic refers to the adults ages 18 and older who reported their physical health was not good for at least 14 of the last 30 days at the time of data collection. To calculate the total number of adults who reported in this way (numerator value), we used the percentage value provided by the CDC and multiplied this value by the total adult population. Note: source does not provide data for all geographic locations, such as in cases where data collection is low.
