Understanding Data

Overview
“Many Americans do not understand the magnitude of the injury problem in this country. Data allow us to show how many people are injured each year and how many die or suffer permanent disabilities as a result of those injuries. Data show us where the biggest injury problems are so we can best focus our resources and data let us know whether our efforts to prevent injuries are effective”(CDC Injury Fact Book)
