2010 Census Coverage Measurement Person Interview and Person Interview Reinterview Operations
A. Justification
1. Necessity of the Information Collection
The U.S. Census Bureau requests authorization from the Office of Management and Budget to conduct the Census Coverage Measurement (CCM) Person Interview (PI) and Person Interview Reinterview (PIRI) operations as part of the 2010 Census. The CCM program will provide estimates of net coverage error and components of coverage error (omissions and erroneous enumerations) for housing units and persons in housing units (see Definition of Terms). The data collection and matching methodologies for previous coverage measurement programs were designed only to measure net coverage error, which reflects the difference between omissions and erroneous inclusions.
The 2010 CCM will be comprised of two samples selected to measure census coverage of housing units and the household population: the population sample (P sample) and the enumeration sample (E sample). The primary sampling unit is a block cluster, which consists of one or more contiguous census blocks. The P sample is a sample of housing units and persons obtained independently from the census for a sample of block clusters. The E sample is a sample of census housing units and enumerations in the same block cluster as the P sample. The results of the housing unit matching operations will be used to determine which CCM and Census addresses will be eligible to go to the CCM Person Interview (PI) Operation. The PI Operations will contain approximately 362,250 sample addresses. The Person Interview Reinterview Operation will be a sample of those cases with an estimate 36,225 sample addresses.
The automated PI instrument will be used to collect the following information for persons in housing units only:
Roster of people living at the housing unit at the time of the CCM PI Interview.
Census Day (April 1, 2010) address information from people who moved into the sample address since Census Day.
Other addresses where a person may have been counted on Census Day.
Other information to help us determine where a person should have been counted as of Census Day (relative to Census residence rules). For example, enumerators will probe for persons who might have been left off the household roster; ask additional questions about persons who moved from another address on Census Day to the sample address; collect additional information for persons with multiple addresses; and collect information on the addresses of other potential residences for household members.
Demographic information for each person in the household on Interview Day or Census Day, including name, date of birth, sex, race, Hispanic Origin, and relationship.
Name and above information for any person who has moved out of the sample address since Census Day (if known).
We also will conduct a quality control operation - PI Reinterview (PIRI) on 10 percent of the PI cases. The purpose of the operation is to confirm that the PI enumerator conducted a PI interview with an actual household member or a valid proxy respondent and conduct a full person interview when falsification is suspected. If PIRI results indicate falsified information by the original enumerator, all cases worked by the original enumerator are reworked by reassigning the cases to a different PI enumerator.
Title 13, United States Code, Section 141 authorizes the Secretary of Commerce to conduct a decennial census of the population, and Section 193 authorizes the Secretary to conduct tests to gather supplementary information related to the census.
2. Needs and Uses
The CCM program will provide estimates of net coverage error and components of coverage error (omissions and erroneous enumerations) for housing units and persons in housing units (see Definition of Terms). Person interview will collect the unit status and independent roster of people who lived at the sample address either at Census Day or Interview Day. These people will be used for person matching.
Information quality is an integral part of the pre-dissemination review of data by the Census Bureau (fully described in the Census Bureau’s Information Quality Guidelines located at http://www.census.gov/quality/). Information quality also is integral to the information collections conducted by the Census Bureau and is incorporated into the clearance process required by the Paperwork Reduction Act.
3. Use of Information Technology
Information technology will be employed during the PI and PIRI operations. PI and PIRI are Computer Assisted Data Collection instruments and interviews are conducted by personal visits or telephone (See Attachments B and C).
Efforts to Identify Duplication
CCM operations are designed to collect information to evaluate the methods used in the 2010 Census and possibly identify new approaches to more accurately measure and prevent (as possible) coverage error (net and components) for housing units and persons in future censuses. This includes estimates of the number of people and housing units duplicated. This effort does not duplicate information collected by any other agency.
5. Minimizing Burden
The proposed information collection consists of collecting demographic and address information about persons rostered in the CCM Person Interview and Person Interview Reinterview operations. Interviews will be conducted at the smallest number of housing units required to adequately estimate net coverage error and the components of net coverage error. Respondents will be asked the minimum number of questions to identify Census Day and Interview Day residence of the sample address and other potential addresses where they may have been counted in the census.
6. Consequences of Less Frequent Collection
Improving census coverage is one of the major goals of reengineering the 2010 Decennial Census Program. If these activities were not conducted, it would adversely affect our ability to measure the coverage of the population in the 2010 Census.
7. Special Circumstances
No special circumstances exist.
8. Consultations Outside the Agency
The Census Bureau published a notice in the Federal Register on June 19, 2009 (Vol. 74, No. 117, PG 29166), inviting public comment on our plans to submit this information collection.
One comment was received from the Brookings Institution (See Attachment D). The letter agrees with the need for both CCM PI and CCM PIRI for the Census Bureau to judge its performance as well as provide essential information. It also made one minor suggestion deemed not relevant for this CCM operation.
9. Paying Respondents
Respondents participating in this survey will not receive any form of compensation for their participation.
10. Assurances of Confidentiality
All respondents will be informed that participation is mandatory, that their responses are confidential, and that all information that could identify individuals will be held in the strictest confidence under applicable Federal statutes. This survey complies with the requirements of the Privacy Act of 1974 and the Paperwork Reduction Act. (See Attachment A – Introductory Letter for CCM PI and PIRI)
11. Justification for Sensitive Questions
The Census Bureau perceives no question in the CCM PI or PIRI questionnaires as being sensitive.
12. Estimate of Hour Burden
A sample of approximately 362,250 housing will be selected spread evenly among the 50 states, District of Columbia and Puerto Rico for the PI operation. A sample of approximately 36,225 housing units will be selected for the PIRI operation in the same areas. To calculate the burden hours, we assumed a theoretical 100 percent response rate and an approximate completion time of 15 minutes per respondent (based on the results from the 2009 Dress Rehearsal). The estimated total annual respondent burden for the PI and PIRI operations is approximately 99,619 hours.
13. Estimate of Cost Burden
There is no cost to respondents, except for the time it takes to respond to the questions.
14. Cost to the Federal Government
The cost incurred by the Census Bureau to conduct the Person Interview field operation is estimated to be about $42,143,247. An inter-divisional Census Bureau team developed the data collection methodologies. The Census Bureau’s Decennial Management Division allocated the resources for the effective and efficient management of the information..
Justification for Change in Burden
This collection is being submitted as new.
