Samples of female hispanic drivers


The proportion of drivers who employ seat belts depends upon things like age (young people are more likely to go unbelted) and gender (women are more likely to use belts). It also depends upon local law. In New York City, police can stop driver who isn't belted. In Boston at the time of survey, police could cite a driver for not wearing a seat belt only if driver had been stopped for some other violation. Here are data from observing random samples of female Hispanic drivers in these two cities:

City Drivers Belted

New York 220 183

Boston 117 68
