Consumer Expenditure Survey, 2013: Interview Survey and Detailed Expenditure Files

The Consumer Expenditure Survey (CE) program provides a continuous and comprehensive flow of data on the buying habits of American consumers, including data on their expenditures, income, and consumer unit (families and single consumers) characteristics. These data are used widely in economic research and analysis, and in support of revisions of the Consumer Price Index. The CE program is comprised of two separate components, each with its own questionnaire and independent sample: (1) the quarterly Interview Survey, and (2) the Diary Survey. This data collection contains the quarterly Interview Survey data, which was designed to collect data on major items of expense which respondents could be expected to recall for 3 months or longer. Items include relatively large expenditures, such as those for property, automobiles, and major durable goods, and those that occurred on a regular basis, such as rent or utilities. The Interview Survey does not collect data on expenses for housekeeping supplies, personal care products, and nonprescription drugs, which contribute about 5 to 15 percent of total expenditures. The 2013 Interview Survey contains eight groups of Interview data files (FMLI, MEMI, MTBI, ITBI, ITII, NTAXI, FPAR, and MCHI), forty-three Detailed Expenditure (EXPN) files, and processing files. The FMLI, MEMI, MTBI, ITBI, ITII, and NTAXI files are organized by the calendar quarter of the year in which the data were collected. There are five quarterly datasets for each of these files, running from the first quarter of 2013 through the first quarter of 2014 (with NTAXI files starting the second quarter of 2013). The FMLI file contains consumer unit (CU) characteristics, income, and summary level expenditures; the MEMI file contains member characteristics and income data; the MTBI file contains expenditures organized on a monthly basis at the Universal Classification Code (UCC) level; the ITBI file contains income data converted to a monthly time frame and assigned to UCCs; and the ITII file contains the five imputation variants of the income data converted to a monthly time frame and assigned to UCCs. The NTAXI file contains federal and state tax information for each tax unit within the CU. The FPAR and MCHI datasets are grouped as 2-year datasets (2012 and 2013), plus the first quarter of 2014, and contain paradata about the Interview survey. The FPAR file contains CU level data about the Interview survey, including timing and record use. The MCHI file contains data about each interview contact attempt, including reasons for refusal and times of contact. Both FPAR and MCHI files contain five quarters of data. The EXPN files contain expenditure data and ancillary descriptive information, often not available on the FMLI or MTBI files, in a format similar to the Interview questionnaire. In addition to the extra information available on the EXPN files, users can identify distinct spending categories easily and reduce processing time due to the organization of the files by type of expenditure. Each of the 43 EXPN files contains five quarters of data, directly derived from their respective questionnaire sections. The processing files enhance computer processing and tabulation of data, and provide descriptive information on item codes. There are two types of processing files: (1) aggregation scheme files used in the published consumer expenditure survey interview tables and integrated tables (ISTUB and INTSTUB), and (2) a vehicle make file (CAPIVEHI). The processing files are further explained in the Interview Survey Users' Guide, Section III.H.9. "Processing Files." In addition to the primary users' guide, the Users' Guide to Income Imputation provides information on how to appropriately use the imputed income data. Demographic and family characteristics data include age, sex, race, marital status, and CU relationships for each CU member. Income information was also collected, such as wage, salary, unemployment compensation, child support, and alimony, as well as information on the employment of each CU member age 14 and over. The unpublished integrated CE data tables produced by the BLS are available to download through NADAC (click on "Other" in the Dataset(s) section). The tables show average and percentile expenditures for detailed items, as well as the standard error and coefficient of variation (CV) for each spending

《消费者支出调查》（CE）项目持续且全面地提供了关于美国消费者购买习惯的数据流，包括其支出、收入以及消费单位（家庭及单身消费者）的特征数据。这些数据在经济学研究和分析中得到了广泛的应用，并支持了对消费者价格指数的修订。CE项目由两个独立的组成部分构成，每个部分均拥有其自身的问卷和独立样本：（1）季度访谈调查；（2）日记调查。本数据收集包含季度访谈调查数据，旨在收集受访者能够回忆起三个月或更长时间内的主要支出项目。这些项目包括相对较大的支出，如房产、汽车和耐用消费品，以及定期发生的支出，如租金或公共事业费。访谈调查不收集家务用品、个人护理产品和非处方药的支出数据，这些支出约占总支出的5%至15%。2013年访谈调查包含八个访谈数据文件组（FMLI、MEMI、MTBI、ITBI、ITII、NTAXI、FPAR和MCHI），四十三份详细支出（EXPN）文件以及处理文件。FMLI、MEMI、MTBI、ITBI、ITII和NTAXI文件按照收集数据的年份的日历季度进行组织。每个这些文件都有五个季度数据集，从2013年第一季度至2014年第一季度（NTAXI文件从2013年第二季度开始）。FMLI文件包含消费单位（CU）特征、收入和汇总水平支出；MEMI文件包含成员特征和收入数据；MTBI文件包含按月组织并在通用分类代码（UCC）级别的支出；ITBI文件包含转换为月度时间框架并分配给UCC的收入数据；ITII文件包含转换为月度时间框架并分配给UCC的收入数据的五种估计变体。NTAXI文件包含消费单位内每个税单位的联邦和州税信息。FPAR和MCHI数据集作为两年数据集（2012年和2013年），加上2014年第一季度，包含访谈调查的辅助数据。FPAR文件包含关于访谈调查的消费单位级别的数据，包括时间和记录使用情况。MCHI文件包含关于每次访谈接触尝试的数据，包括拒绝原因和接触时间。FPAR和MCHI文件均包含五个季度的数据。EXPN文件包含支出数据和辅助描述性信息，通常在FMLI或MTBI文件中不可用，其格式与访谈问卷类似。除了在EXPN文件中可获得的额外信息外，用户还可以通过文件的支出类型组织轻松识别不同的支出类别，并减少由于文件组织而导致的处理时间。每个43个EXPN文件都包含五个季度的数据，直接从其相应的问卷部分中提取。处理文件提高了计算机数据处理和制表效率，并提供了关于项目代码的描述性信息。处理文件有两种类型：（1）用于发布消费者支出调查访谈表格和集成表格（ISTUB和INTSTUB）的汇总方案文件；（2）车辆制造商文件（CAPIVEHI）。处理文件在访谈调查用户指南的第三部分.H.9节“处理文件”中进一步解释。除了主要用户指南外，《收入估计用户指南》还提供了关于如何适当使用估计收入数据的信息。人口和家庭特征数据包括每个消费单位成员的年龄、性别、种族、婚姻状况和CU关系。还收集了收入信息，如工资、薪金、失业补偿、子女抚养费和赡养费，以及每个14岁及以上消费单位成员的就业情况。美国劳工统计局（BLS）生产的未发表综合CE数据表可通过NADAC下载（在数据集（s）部分点击“其他”）。这些表格显示了详细项目的平均和百分位数支出，以及每个支出的标准误差和变异系数（CV）。
