Methodology Notes

NOPUS uses observational data collected at intersections, highway ramps, and parking lots. Four observers (each responsible for a different seat in the vehicle) report occupant restraint use.

Data by race and age are not reported because race and age are subjectively assessed by roadside observers and are, therefore, considered unreliable.

Description of Changes Since the Healthy People 2020 Launch

In 2012, the target was revised from 92.4 to 92 due to the available precision of the baseline value. The baseline value is 84, not 84.0.
