Methodology Notes

NSUBS uses observational data collected at a probability sample of gas stations, day care centers, recreation centers, and restaurants in five national fast-food chains across the United States. The choice of these types of data collection sites stems from the necessity of observing restraint use from a close range in a slow-moving or stopped vehicle (as is required in order to distinguish a seat belt being used in conjunction with a backless booster seat from a seat belt being used alone), combined with the desire to capture large numbers of children.

Caveats and Limitations
NHTSA recommends that children can graduate from booster seats to seat belts once they fit properly. Seat belts fit properly when the lap belt lays across the upper thighs and the shoulder belt fits across the chest (usually at age 8 or when they are 4’9” tall). Due to the limited sample size of this study, restraint type use could not be analyzed simultaneously by the age and height requirements.
Changes Between HP2010 and HP2020
This objective differs from Healthy People 2010 objective 15-20, which tracked child restraint use among children <7 years. Healthy People 2020 includes four objectives (IVP-16.1 through IVP-16.4) to separately accommodate the four age-specific guidelines for types of child restraints.
