Scope and Method of SurveySurvey Coverage
All of the nation's metropolitan areas, except those in Alaska and Hawaii, are eligible candidates for study. Since the Bureau cannot afford to study all metropolitan areas, we select a sample of areas to represent all metropolitan areas. Areas are scientifically selected based on size, economic characteristics, and geographic location. A few metropolitan centers of federal employment are added to meet the needs of federal pay administration. In addition to the metropolitan areas, we select a sample of non metropolitan counties to be surveyed. This sample is designed to represent all areas within the conterminous 48 states.This sample of areas is designed to yield national and regional, as well as locality, data. The Employment Standards Administration (ESA), of the U.S. Department of Labor, uses BLS data to help administer the Service Contract Act and selects specific areas for study. These areas range from a single county, parish, or city to an entire State, or, in the case of Deep Sea Transportation Surveys, the Nation.
OCSP surveys have a full or limited industrial scope. Most surveys use the full scope which covers establishments employing 50 workers or more in goods producing industries (mining, construction, and manufacturing); service producing industries (transportation, communications, electric, gas, and sanitary services; wholesale trade; retail trade; finance, insurance, and real estate; and service industries); and State and local governments. Private households, agriculture, the Federal Government, and the self-employed are excluded from the survey coverage. Limited scope surveys do not cover governments, mining and construction establishments, and their coverage of services is limited (health and education are the most notable exclusions). The limited scope surveys are a result of 1) our earlier Area Wage Survey Program, and are still used in some localities because of resource limitations, and 2) ESA selected areas, where the limited scope fits their needs. Limited scope surveys not selected by ESA will become full scope surveys with new samples starting in 1996 and 1997.
