2. Sampling Procedures
The mailing list for the COS consists of a certainty component including all multi-establishment companies with 50 employees or more. The establishment sample will be drawn by industry.
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.
Testing Procedures
No other test of procedures has been conducted because the methodology is very similar to what has been used successfully since 1973.
5. Contact for Statistical Aspects and Data Collection
