National Data Resources

Many organizations provide national data sources for injury, illness, death, and criminal justice data. Most of these datasets are accessible on the Internet. Some allow you to access pre-defined reports or query an existing database. Others allow you to download the data and calculate your own statistics. There may be a fee for
downloaded data, but the query systems are generally
provided at no cost to the user.
Some national repositories also provide state level information.

National data sources are useful because they provide national and often state level information from credible sources. You have the flexibility of using pre-defined query systems or downloading data directly for analysis. There may be a fee for downloaded data, but the query systems are generally provided at no cost to the user. Data are de-identified already, so confidentiality issues are not a major concern. All data sources may have a significant lag time before data are compiled (usually 2-3 years).

The following is a chart of some helpful data sources:
