Multiple Worksite Report and the Report of Federal Employment and Wages

B. Collection of Information Employing Statistical Methods

1a. Universe

Multiple Worksite Report - The universe for this program will include the multi-establishment employers subject to Unemployment Insurance coverage in the 50 States, District of Columbia, Puerto Rico, and the Virgin Islands. The employers covered by this census are those having more than one establishment under the same UI account number within the State and the sum of the employment in all of their secondary establishments is 10 or greater. There are approximately 182,800 employers that fit these criteria. The most current QCEW working file(s) for each State serves as the business list.

Report of Federal Employment and Wages/DOD Collection - The universe for this census will include the Federal employers subject to Unemployment Compensation for Federal Employees coverage in the 50 States, District of Columbia, Puerto Rico, and the Virgin Islands. The most current QCEW working file(s) for each State serves as the business list.

b. Sample Size

Multiple Worksite Report - Since this is a quarterly census of multiple worksite businesses, the sample size will be 182,806, the same as the universe. With a loss of 5% of selected units due to out-of-business, duplicates, or non-mailables, and a 15% non-response, the number of respondents is expected to be 146,245. This number may increase or decrease depending upon changes with the census of multi-establishment employers.

Report of Federal Employment and Wages - Since this is a quarterly census of Federal installations multiple worksites, the sample size will be 3,067 non-defense respondents as well as the 5 major civilian (appropriated and non-appropriated) defense respondents, the same as the universe.

2a. Sample Allocation and Selection Procedures

The sampling frame used by each State is the most current QCEW working file(s). All employers that report more than one establishment under the same UI account number within the State and where their employment for secondary establishments is greater than or equal to 10 will be included in the MWR census. All Federal employers within each State will be included in the RFEW census.

b. Estimation Procedure

These data are being collected to ensure the micro data on the longitudinal QCEW data and on the QCEW Report are on an establishment/installation basis instead of some consolidated level consisting of two or more establishments/installations. Therefore, after data are edited and reconciled for apparent inconsistencies and completeness, these data will be the micro-data on the longitudinal QCEW data. Estimates of totals at higher tabulation levels for the QCEW Report will be the sum of the appropriate micro-level data. Since this is a census, the estimates are not subject to any sampling error. Therefore, no standard errors will be calculated.

c. Accuracy

Because a census is being conducted, the estimates are not subject to any sampling error.

d. Problems

There are no unusual problems requiring specialized sampling procedures.

e. Frequency

This is conducted quarterly.

3a. Response

To maximize the response rate for the MWR and the RFEW, an explanation of the importance of the information, the need for employer cooperation and electronic reporting options are emphasized.

Additionally, States conduct two follow-up mailings after the initial mailing and contact key non-respondents by telephone

Employers whose total U.I. account employment within a State is less than 10 are not subject to this report.

b. Non-response Adjustment

A proration adjustment procedure is used to impute data for non-respondents. The data are prorated using the previous quarters’ distribution of employment and wages and the current UI contributions report for the master unit.

c. Reliability

Because this study is a census, no sampling errors are calculated.

To control non-sampling errors, quality control procedures were incorporated into the survey's design. These procedures include follow-up of all non-respondents and validation of all edit failures. Additionally, the States and Regions are given training and assistance in conducting this quarterly census. For example, BLS Washington provided the States with software to print the forms and to process the data. The automation of most survey operations reduced many sources of non-sampling errors.

4. Tests

No tests have been conducted since this is an ongoing data collection activity since 1991.
