Data Element Dictionary ================================================================================ Section 1 ================================================================================ The following is a definition of: OCCUPATIONAL INJURIES AND ILLNESSES INDUSTRY DATA (IS) Survey Description: Occupational injury and illness counts and incidence rates are annual measures of the level and frequency of work-related injuries and illnesses. The rate equals the form of the number of injuries and illnesses per 100 full-time employees. Data collected through the annual survey are based on records which employers maintain under the Occupational Safety and Health Act. Data include all cases resulting from accidents or exposure in the work environment that result in a nonfatal illness or injury. Some of these cases involve lost work time-- the incident may result in a work absence, restriction of work or motion, or transfer to another job. Other recordable cases do not involve any lost days. Recordkeeping guidelines are maintained by the Occupational Safety and Health Administration. Virtually the entire private sector is covered by the survey, except self-employed individuals, farms with fewer than 11 employees, and employers regulated by other Federal safety and health laws. National estimates exclude Federal, State, and local government agencies, but data for selected States include State and local government. Data conforming to definitions of recordable occupational injuries and illnesses for coal, metal and nonmetal mining, and railroad transportation are provided by the Mine Safety and Health Administration, U.S. Department of Labor, and the Federal Railroad Administration, U.S. Department of Transportation. The incidence rates are produced for industries which are based on the 2012 North American Industry Classification System (NAICS). The survey sample design uses stratified random sample with a Neyman allocation. The characteristics used to stratify the units are the States, NAICS code, and employment. The data for all reporting units in each industry are expanded by the inverse of the sampling ratio, and benchmarked to the appropriate employment level in each industry. Reports are collected from about 180,000 sample units. Summary Data Available: Incidence rates and counts are calculated for three categories for total recordable cases: (1) injury and illness combined, (2) injury only; and (3) illness only. Additionally, estimates of incidence rates and case counts are also available for various severity classifications. For each injuries and illnesses in each industry, the incidence rates and numbers of cases are available for total nonfatal recordable cases; cases with days away from work, job transfer or restriction; cases with days away from work; cases with job transfer or restriction only; and other recordable cases. Data also include rates and numbers of cases, by various illness categories: skin diseases or disorders, respiratory conditions, poisonings, hearing loss, and all other illnesses. Data for an unpublished industry were included in the total for the broader industry level of which it is a part. Calculation of Incidence Rates: The incidence rates represent the number of injuries and/or illnesses per 100 full-time workers and were calculated as: (N/EH) x 200,000 (20,000,000 for illness rates). where: N = number of injuries and/or illnesses. EH = total hours worked by all employees during the calendar year. 200,000 = base for 100 full-time equivalent workers (working 40 hours/week, 50 weeks/year). 20,000,000 =base for 10,000 full-time equivalent workers (working 40 hours/week, 50 weeks/year). Frequency of Observations: All data are annual. Data Characteristics: Rates are stored to one decimal place. Number of cases are in thousands.

BLS time series data are typically produced at monthly intervals and represent data ranging from a specific consumer item in a specific geographical area whose price is gathered monthly to a category of worker in a specific industry whose employment rate is being recorded monthly, etc. The FTP files are organized such that data users are provided with the following set of files to use in their efforts to interpret data files: a) a series file (only one series file per survey) b) mapping files c) data files The series file contains a set of codes which, together, compose a series identification code that serves to uniquely identify a single time series. Additionally, the series file also contains the following series-level information: a) the period and year corresponding to the first data observation b) the period and year corresponding to the most recent data observation. The mapping files are definition files that contain explanatory text descriptions that correspond to each of the various codes contained within each series identification code. The data file contains one line of data for each observation period pertaining to a specific time series. Each line contains a reference to the following: a) a series identification code b) year in which data is observed c) period for which data is observed (A01, M13, Q05, and S03 indicate annual averages) d) value e) footnote code (if available) ================================================================================= Section 4 ================================================================================= File Structure and Format: The following represents the file format used to define is.series. Note that the Field Numbers are for reference only; they do not exist in the database. Data files are in ASCIS text format. Data elements are separated by tabs; the first record of each file contains the column headers for the data elements stored in each field. Each record ends with a new line character.
