- Race (Current Population Survey)
The CPS provides data by race, with the race given by the household respondent. Since 2003, respondents are allowed to choose more than one race; previously, multiracial persons were required to select a single primary race. Persons who select more than one race are classified separately in the category “two or more races.” Persons who select one race only are classified in one of the following five categories: 1) white, 2) black or African American, 3) Asian, 4) Native Hawaiian and other Pacific Islander, and 5) American Indian or Alaska Native. Only data for whites, blacks, and Asians are currently published because the number of survey respondents for the other racial categories is not large enough to produce statistically reliable estimates.
- Recordable injuries and illnesses (Safety and Health statistics)
Recordable cases include work-related injuries and illnesses that result in one or more of the following: death, loss of consciousness, days away from work, restricted work activity or job transfer, medical treatment (beyond first aid), significant work-related injuries or illnesses that are diagnosed by a physician or other licensed heath care professional (these include any work-related case involving cancer, chronic irreversible disease, a fracture or cracked bone, or a punctured eardrum); additional criteria include any needle-stick injury or cut from a sharp object that is contaminated with another person's blood or other potentially infectious material, any case requiring an employee to be medically removed under the requirements of an OSHA health standard, tuberculosis infection as evidenced by a positive skin test or diagnosis by a physician or other licensed health care professional after exposure to a known case of active tuberculosis.
