Protocol - Household Roster-Relationships

Add to My Toolkit
Description

The respondent is asked to list all the people who currently live in the household, beginning with the person who owns or rents the dwelling (householder), followed by the spouse or partner of that person, and then other household members. For each person listed, the respondent reports relationship to the householder and spouse of householder, sex, age, and marital status.

Specific Instructions

Household roster questions are about the people who live in the household rather than the individual respondent; as a result, the questions need to be addressed to the head or other knowledgeable adult in the household. If annual household income questions are asked, household roster questions should precede them because the two sets of questions are linked.

Personnel and Training Required

This question is administered by an interviewer with a paper-and-pencil or computer-assisted interview. The interviewer must be trained to conduct personal interviews with individuals from the general population. The interviewer must be trained and found to be competent (i.e., tested by an expert) at the completion of personal interviews. The interviewer should be trained to prompt respondents further if a "don’t know" response is provided.

Equipment Needs

Either a paper-and-pencil or computer-assisted instrument may be used. If a computer-assisted instrument is used, computer software may be necessary to develop the instrument. The interviewer will require a laptop computer/handheld computer to administer a computer-assisted questionnaire.

Requirements
Requirement CategoryRequired
Major equipment No
Specialized training No
Specialized requirements for biospecimen collection No
Average time of greater than 15 minutes in an unaffected individual No

Measure Name

Household Roster-Relationships

Release Date

May 31, 2016

Definition

Question asking the respondent who lives in the household and about his or her relationship with them.

Purpose

Household rosters enumerate the people who live in the household and record some of the characteristics of those people (such as age and sex) and how they are related to one another. The data can be used to describe household size, structure, and composition. Household characteristics have an effect on the socioeconomics and lifestyles of the household inhabitants. Researchers are able to constitute family and nonfamily households from a household roster. This information also illustrates whether multiple generations of a family share the same residence.
