Annual & Quarterly Services

Quarterly Services Survey Methodology

A survey is sent to a sample of approximately 17,000 service providers with paid employees that operate in the covered sectors. Those in the sample can choose to respond though mail, fax, or internet reporting.

In order to be eligible, service businesses must be in the Business Register, which contains all Employer Identification Numbers (EINs) for listed businesses and locations of multi-establishment companies. EINs may represent one or more establishments and firms may have one or more EINs.

The sample is updated quarterly to reflect births and deaths, adding new employer businesses identified in the Business and Professional Classification Survey and deleting firms and EINs that are no longer active. Learn More »
