OMB Control Number 0607-0925

PART B – Collections of Information Employing Statistical Methods

1. Universe and Respondent Selection

The 2012 Economic Census Classification Report for the Construction, Manufacturing, and Mining Sectors and Selected Wholesale Industries will be an enumeration of partially classified manufacturing, mining, and construction establishments in the 50 states and the District of Columbia. Additionally, wholesale establishments currently classified in select industries will be included in the mailout to verify correct classification due to changes in NAICS for 2012. The mailing list or the NC-99026 is derived from the Business Register. As part of the 2012 Economic Census, this form will be used to obtain physical location and classification information needed to assign detailed NAICS codes.

	FY 2012	FY 2013
Total universe of active establishments	75,000	75,000
Number of establishments to be mailed	75,000	75,000
Expected response rate (85 percent)	63,750	63,750

2. Procedures for Collecting Information

1. Statistical Methodology for Stratification and Sample Selection

The Census Bureau will mail the NC-99026 to obtain classification information. The NC-99026 will contain lists of classification codes and descriptions of business activities. An establishment is to select the activity that best describes its business by checking the box next to the activity listed.

2. Estimation Procedure

There are no data published from this survey. Survey results will be used to update the Business Register so that more reliable data will be collected in the Census.

3. Degree of Accuracy Needed

The accuracy of this information collection is not affected by sampling error. These measures are based in a complete enumeration of the target establishment universe.

4. Unusual Problems Requiring Specialized Sampling Procedures

There are no known problems that will require specialized sampling procedures for this survey.

5. Use of Periodic Data Collection to Reduce Burden

The Census Bureau uses periodic information collection in conjunction with conducting an Economic Census to update its Economic Census mailing lists as required by Title 13, U.S.C., Section 131.

3. Methods to Maximize Response

This information collection will maximize response through the following means:

1. mailing materials that emphasize the mandatory and confidential nature of Census reports, as provided by Title 13, U.S.C.;

2. effective Census questionnaires and instructions that simplify reporting and minimize response burden;

3. systematic mail follow-up for nonresponse supplemented by telephone follow-up for selected firms; and

4. allowing respondents to report electronically via the Internet.

4. Testing of Procedures

This information collection will use procedures that are based on the 2006 Refile Classification Survey, the 2007 Economic Census Classification Report, and a considerable body of other experience with the Economic Census and surveys. Previous Economic Censuses also have been the subject of evaluation studies that have examined methodology, conceptual issues, and related statistical questions.
