Résumé
Bureau of Labor Statistics (2017). Consumer Expenditures: Age of Reference Person: Under 25 | Country: USA | Category: Housing | Socioeconomic Indicator*: Cellular phone service, 2013-2016. Data-Planet™ Statistical Ready Reference by Conquest Systems, Inc. [Data-file]. Dataset-ID: 002-008-023. Dataset: Age of reference person. Reference person is the first member mentioned by the respondent when asked to "Start with the name of the person or one of the persons who owns or rents the home." It is with respect to this person that the relationship of the other consumer unit members is determined. The Consumer Expenditure Survey is a nationwide survey conducted annually for the Bureau of Labor Statistics (BLS) by the United States Census Bureau. The consumer expenditures program consists of two surveys--the Quarterly Interview Survey and the Diary Survey--that provide information on the characteristics, expenditures, and income of American consumers. For the diary survey, respondents complete a diary of expenses for two consecutive 1-week periods. The diary survey is designed to obtain data on frequently purchased items, such as food or housekeeping supplies, that respondents are less likely to recall over time. For the interview survey, respondents report data to an interviewer. Each sample household is interviewed once per quarter, for five consecutive quarters. This survey is designed to collect data on major items of expense, such as property purchases or vehicle purchases, and those that occur on a regular basis, such as rent or utility payments, that respondents recall for 3 months or longer. Each year approximately 30,000 persons participate in the Quarterly Interview Survey, and 15,000 participate in the Diary Survey. The dataset presents annual income and expenditures integrated from the Interview and Diary surveys in varying detail, classified by income, age, consumer unit size, and other demographic characteristics of consumer units. Expenditures consist of the transaction costs, including excise and sales taxes, of goods and services acquired during the interview or recordkeeping period. In many cases the hierarchy used to display the expenditure items will indicate the scope of a particular category. For example, the hierarchy shows that Entertainment covers events requiring admissions, pets and toys, entertainment equipment, and outdoor recreational equipment. Additional detail can be found in the BLS Glossary: http://www.bls.gov/cex/csxgloss.htm Expenditures consist of the transaction costs, including excise and sales taxes, of goods and services acquired during the interview or recordkeeping period. Detailed inclusions and exclusions for expenditure categories are available on the BLS web site.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
