Caveats and Limitations: 
Since the Numerator questions focus on leisure-time physical activities only, these data may not include physical activity by people whose jobs require regular or vigorous physical activity.
Trend Issues: 
Beginning with 2018, the American Community Survey questions are no longer available in the NHIS. As a result, tabulated data by disability are discontinued after 2017.
Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 22-4 in that the objective has been modified to reflect the 2008 Federal Physical Activity Guidelines for Americans. The data for the Healthy People 2010 and 2020 objectives are not comparable.
