On occasion, updates are made to some variables. The codebook structure was developed iteratively by reaching a consensus on the analysis of shared transcripts to create an all-encompassing set of codes, with definitions, inclusion and exclusion criteria, and exemplar text from the transcripts. For any published analysis using downloadable CHS data, please reference the URL of this webpage, the CHS year(s) analyzed and the date on which the dataset was downloaded (suggested citation below).The codebook may include a dataset’s record layout, list of variable names and labels, concepts, categories, cases, missing value codes, frequency counts, notes, universe statements, and so on. Before analyzing the data below, read our analytic considerations. A codebook is an essential document that informs the data user about the study, data file (s), variables, categories, etc., that make up a complete dataset.Please complete the EPI data request form to request more information on multi-year survey weights. Survey data from 2009 and after cannot be combined with earlier years. This may include explanations on meaning, numerical values, range, units of measurement, sources (of for example questionnaires), classification schemes used, and/or labels of questions asked. Multi-year weights are only available for data years 2002-2008, and for select two-, three- and five-year combinations from 2009-2020. A codebook explains all the concepts and/or variables that are present in the datafiles. If an analysis requires the combination of multiple years of data, a multi-year weight is needed.The Health Department's suggested guidelines for CHS data reliability (PDF) incorporate relative standard error (RSE), confidence interval width, and sample size. Organizations have various guidelines for when an estimate should be considered unreliable. Some conditions may be rare or the sample sizes for some populations quite small, making CHS estimates potentially unreliable.A question matrix (PDF) shows which topics are available each year.Code in SAS without SUDAAN (SAS), as well as code in R (R), are also available. Codebook development Codebook development was a top-down/bottom-up process. Annotated sample code for analysis using SAS and SUDAAN is provided for each year below. The sample selection process is summarised in figure 1. Due to the complex sampling design of the CHS, data must be analyzed in a software program capable of handling complex survey data (such as SUDAAN or STATA).For more information on the CHS, visit our Methodology page.īefore downloading any datasets, review the following information: (See Dat files in this collection).Datasets are available on this page for each year of the Community Health Survey (CHS). The data are available line by line (one line per case) in a "dat" format. The total number of cases in this 1% sample is over 11 million. Sample universe: ANES 2016 web and face-to-face post-election respondents Sample composition: ANES 2016. The data-set on the China Archive consists of separate 1% samples for each of China's three municipalities (Beijing, Shanghai and Tianjin) and provinces and autonomous areas. Methodology File User Guide and Codebook. The codebook lists all the data cleaning tasks that you wish to. This is the 1% 1990 China Census data-set now residing in the China Archives collection. Complete template: After this, you can simply fill out the template, which creates the codebook. This code simply describes that the sentence involves pigeons. The China Population and Information Research Center subsequently released a 1% Sample of the individual questionnaires from the 1990 Census. For example, in the sentence: Pigeons attacked me and stole my sandwich. An example for an elaborated naming convention is the naming convention of. The main source of data from the 1990 census is: Population Census Office under the State Council 1991, Major Figures of the Fourth National Population Census of China, Beijing: China Statistical Publishing House. Codebooks are an inevitable component of data documentation and data sharing. # of persons in HH # of births in HH in 1989 # of deaths in HH in 1989 # of registered persons absent from the HH, and the name and sex. The 1990 census questionnaire contained some 19 items (see the Codebook in this collection), including the following: name relationship sex age nationality (self id) registration status for persons 6 years +: education for persons age 15 years +: industry occupation "nonworking" person status marital status residence in 1985 for women aged 15-64: # children ever born # children surviving for women aged 15-49: birth and birth order in 1989 household items: HH type (domestic or collective) HH serial No. More than 1.1 billion persons were counted in the 1990 census. DescriptionOn July 1, 1990, the People's Republic of China conducted the country's 4th national census.
