2. Sampling Procedures
The mailing list for the COS consists of a certainty component including all multi-establishment companies. 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. A representative sample of single-establishment enterprises will also be drawn from the single-location companies that will be mailed in the Economic Census. The sample will include enterprises with large administrative data values as well as a component of smaller companies selected by Enterprise industry and size.
3. Maximize response rate and non-response
There will be four 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.
