Analysis Units

The method(s) used to collect the data. </div><ul><li>audio computer-assisted self interview (ACASI) -- Interview administered by the respondent, without an interviewer, assisted by a computer with audio prompts.</li><li>audiovisual touch-screen computer-assisted self-interview (AVT-CASI) -- Interview administered by the respondent, without an interviewer, assisted by a touchscreen computer.</li><li>coded on-site observation -- Observation that is conducted in a natural environment.</li><li>coded video observation -- Observation that is conducted by video.</li><li>cognitive assessment test -- Assessment of knowledge, skills, aptitude, or educational achievement by means of specialized measures or tests.</li><li>computer-assisted personal interview (CAPI) -- Data collection method in which the interviewer reads questions to the respondents from the screen of a computer, laptop, or a mobile device like tablet or smartphone, and enters the answers in the same device. The administration of the interview is managed by a specifically designed program/application.</li><li>computer-assisted self-interview (CASI) -- Respondents enter the responses into a computer (desktop, laptop, Palm/PDA, tablet, etc.) by themselves. The administration of the questionnaire is managed by a specifically designed program/application but there is no real-time data transfer as in CAWI, the answers are stored on the device used for the interview. The questionnaire may be fixed form or interactive. Includes VCASI (Video computer-assisted self-interviewing), ACASI (Audio computer-assisted self-interviewing) and TACASI (Telephone audio computer-assisted self-interviewing).</li><li>computer-assisted telephone interview (CATI) -- The interviewer asks questions as directed by a computer, responses are keyed directly into the computer and the administration of the interview is managed by a specifically designed program.</li><li>face-to-face interview -- Data collection method in which a live interviewer conducts a personal interview, presenting questions and entering the responses. Use this broader term if not CAPI or PAPI, or if not known whether CAPI/PAPI or not.</li><li>mail questionnaire -- Self-administered survey using a traditional paper questionnaire delivered and/or collected by mail (postal services).</li><li>mixed mode -- Use when there are two or more modes of collection.</li><li>on-site questionnaire -- Data collection method in which the information is gathered on-site.</li><li>paper and pencil interview (PAPI) -- The interviewer uses a traditional paper questionnaire to read the questions and enter the answers.</li><li>record abstracts -- Presentation of information in a condensed form, by reducing it to its main points. For example, abstracts of interviews or reports that are published and used as data rather than the full-length interviews or reports.</li><li>remote sensing -- The acquisition of information about an object or phenomenon without making physical contact with the object, especially the Earth. In current usage, the term 'remote sensing' generally refers to the use of satellite- or aircraft-based sensor technologies to detect and classify objects on Earth.</li><li>self-enumerated questionnaire -- Data collection method in which the respondent reads or listens to the questions, and enters the responses by him/herself; no live interviewer is present, or participates in the questionnaire administration. If possible, use a narrower term. Use this broader term if the method is not described by any of the narrower terms - for example, for PDF and diskette questionnaires.</li><li>telephone audio computer-assisted self interview (TACASI) -- Interview administered by the respondent, without an interviewer, on the telephone, assisted by a computer.</li><li>telephone interview -- Interview administered on the telephone. Use this broader term if not CATI, or if not known whether CATI or not.</li><li>web-based survey -- An interview conducted via the Internet. For example, interviews conducted within online forums or using web-based audio-visual technology that enables the interviewer(s) and interviewee(s) to communicate in real time.</li><li>web scraping -- A technique employed to extract large amounts of data from websites whereby the data is extracted and saved to a local file or to a database.</li></ui>

Data Type(s)

Describes the procedures the researchers used to contact subjects and/or to collect the data. Such detail could include how surveys were prepared and administered, how interviews were conducted, or how the data were obtained and compiled, as well as information about deadlines and follow-ups to respondents.

Study Design

Describes the concept of the study in detail. The information is similar to that in the Summary field, but more detailed. Such information can include descriptions of the purpose, objectives, and what researchers intended to achieve, as well as lists of questions that the study sought to answer. Historical or background information about the research project is relevant to this field as well.

Study Purpose

The smallest geographic unit represented in the data that can be analyzed. Possible values: Area code Administrative region Block Census Block Census Block group Census division Census enumeration area Census region Census tract City Congressional district Consolidated Metropolitan Statistical Area (CMSA) Continent Core-based statistical area Country County District Ecological zone Electoral district Electoral ward Enumeration area Federal court district FIPS code Geo-political unit (GPU) Geocoded street location Grid coordinates Metropolitan Statistical Area (MSA) Municipality Neighborhood Neighborhood cluster Other Police district Police jurisdiction Police patrol/beat Police precinct Police sector Postal code Prefecture Primary Metropolitan Statistical Area (PMSA) Primary Sampling Units (PSUs) Province Public use microdata area (PUMA) School district State State legislative district Street address Territory Town Township Traffic analysis zone (TAZ) United Kingdom Standard Statistical Regions (SSR) University campus Village Voting Precinct Ward Watershed Zip Code</div>

Smallest Geographic Unit

The percentage of respondents in the sample who participated in the study.

Response Rates

Describes how the cases that appear in the study were selected (e.g., random, convenience, snowball). The sample is a selection out of the universe of all possible relevant cases (e.g. adults in the United States, housing units in three counties of Michigan, etc.) that could have been included in the study. A detailed discussion of such things as sampling error or other limitations of the sampling methodology is not required here. If the sampling description is available in a printed publication, a complete citation may be provided. Note that some studies, such as censuses, do not utilize samples but include all members of the universe.

Sampling Method

Description of Variables

Methodology

Tells when the data were physically collected. The Collection Time Frame field is a text description of the collection dates or collection date ranges.

Date of Collection

A description of technical details and other characteristics of the data collection (such as unique authoring, dissemination, or processing information) that cannot be recorded in the other metadata fields but constitute important information for the user.

Collection Notes

The group of persons or other elements that are the object of the study and to which the study results refer. Age, nationality, and residence commonly help to delineate a given universe, but any of a number of factors may be involved, such as sex, race, income, veteran status, criminal convictions, etc. The universe may consist of elements other than persons, such as housing units, court cases, deaths, countries, etc. In general, it should be possible to tell from the description of the universe whether a given individual or element (hypothetical or real) is a member of the population under study.
