Technical Note The data in this release were collected through a supplement to the May 2012 Current Population Survey (CPS). The CPS, which is conducted by the U.S. Census Bureau for the Bureau of Labor Statistics (BLS), is a monthly survey of about 60,000 eligible households that provides information on the labor force status, demographics, and other characteristics of the nation's civilian noninstitutional population age 16 and over. The May 2012 supplement was designed to gather data in several specific areas related to the employment situation of persons with disabilities. The collection of these data was sponsored by the U.S. Department of Labor's Office of Disability Employment Policy. Information in this release will be made available to sensory- impaired individuals upon request. Voice phone: (202) 691-5200, Federal Relay Service: (800) 877-8339. Definitions and concepts from the monthly CPS Disability status. The monthly CPS uses a set of six questions to identify persons with disabilities. In the CPS, persons are classified as having a disability if there is a response of "yes" to any of these questions. Persons who respond "no" to all of these questions are classified as having no disability. The disability questions are as follows. This month we want to learn about people who have physical, mental, or emotional conditions that cause serious difficulty with their daily activities. Please answer for household members who are 15 years old or over. --Is anyone deaf or does anyone have serious difficulty hearing? --Is anyone blind or does anyone have serious difficulty seeing even when wearing glasses? --Because of a physical, mental, or emotional condition, does anyone have serious difficulty concentrating, remembering, or making decisions? --Does anyone have serious difficulty walking or climbing stairs? --Does anyone have difficulty dressing or bathing? --Because of a physical, mental, or emotional condition, does anyone have difficulty doing errands alone such as visiting a doctor's office or shopping? The CPS questions for identifying individuals with disabilities are only asked of household members who are age 15 and older. Each of the questions ask the respondent whether anyone in the household has the condition described, and if the respondent replies "yes," they are then asked to identify everyone in the household who has the condition. Labor force measures from the CPS are tabulated for persons age 16 and older. More information on the disability questions and the merits and limitations of the CPS disability data is available on the BLS Web site at www.bls.gov/cps/cpsdisability_faq.htm. Labor force status. Employed persons are all those who, during the survey reference week, (a) did any work at all as paid employees; (b) worked in their own business, profession, or on their own farm; or (c) worked 15 hours or more as unpaid workers in a family members business. Persons who were temporarily absent from their jobs because of illness, vacation, labor dispute, or another reason also are counted as employed. Unemployed persons are those who had no employment during the reference week, were available for work at that time, and had made specific efforts to find employment sometime during the 4-week period ending with the reference week. Persons who were waiting to be recalled to a job from which they had been laid off need not have been looking for work to be classified as unemployed. Civilian labor force comprises all persons classified as employed or unemployed. Unemployment rate represents the number of unemployed persons as a percent of the civilian labor force. Not in the labor force includes all persons who are not classified as employed or unemployed. Not employed includes persons who were unemployed or not in the labor force. Additional information on the concepts and methodology of the CPS is available on the Internet at www.bls.gov/cps/documentation.htm.

Some people are in temporary jobs that last only for a limited time or until the completion of a project. Is your job temporary? 1. Yes 2. No Reliability of the estimates Statistics based on the CPS are subject to both sampling and nonsampling error. When a sample, rather than the entire population, is surveyed, there is a chance that the sample estimates may differ from the true population values they represent. The component of this difference that occurs because samples differ by chance is known as sampling error, and its variability is measured by the standard error of the estimate. There is about a 90-percent chance, or level of confidence, that an estimate based on a sample will differ by no more than 1.6 standard errors from the true population value because of sampling error. BLS analyses are generally conducted at the 90-percent level of confidence. The monthly CPS data also are affected by nonsampling error. Nonsampling error can occur for many reasons, including the failure to sample a segment of the population, inability to obtain information for all respondents in the sample, inability or unwillingness of respondents to provide correct information, and errors made in the collection or processing of the data. Additional information on the reliability of data from the CPS and estimating standard errors is available at www.bls.gov/cps/documentation.htm#reliability.
