B. Collection of Information Employing Statistical Methods

1. Universe and Respondent Selection

The mailing list for the COS is derived from the BR. The COS sample will be drawn from this list which consists of all known multi and single-establishment companies.

Estimated Universe and Sample
	Universe	Sample Size
Multi-establishment enterprises
Companies	200,000	43,000
Establishments	1,600,000	1,200,000
Single establishment enterprises	5,800,000	5,000
Nonemployer enterprises	21,000,000	0

2. Sampling Procedures

The mailing list for the COS consists of a certainty component including all multi-establishment companies with 250 or more employees. In addition, a sample of multi-establishment companies with administrative data values that substantially exceed normal industry values are included. We expect these companies to often have organizational changes such as new establishments, closed/sold establishments, change to industry classification, or changes to Federal EIN. A non-certainty component of multi-establishment companies are drawn by industry and size.

3. Maximize response rate and non-response

There will be three mail follow-ups plus selected telephone calls to large companies. This has provided an adequate response rate for past surveys. The response rate in previous years has exceeded 84 percent.

4. Testing Procedures

No other test of procedures has been conducted because the methodology is very similar to what has been used successfully since 1973.
