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 when children outgrow their rear-facing seats (at a minimum age 1 and at least 20 pounds, but preferably not until they have reached the manufacturer’s height or weight limit) they should ride in forward-facing child safety seats, in the back seat, until they reach the upper weight or height limit of the particular seat (usually at around age 4 and 40 pounds). Due to the limited sample size of this study, restraint type use could not be analyzed simultaneously by the age and weight 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.
