Household Survey Data Accuracy Assessment

Unfold the household survey is the international way for countries to know people’s Living conditions. The household survey system of developed countries such as the United States, Canada and Germany has been quite perfect. But our country present household survey work is mainly on the way of recording cash receipts and cash disbursements of accounts. Try to objectively reflect the consumption demand of urban residents, and social modernization. It is the window for the governments at all levels of community, to understand the livelihood of the people. It is the basis of much important work, such as national employment, distribution, circulation, supply policy and determine the consumer price index weighting work, so the accuracy of the data is extremely important.But due to the limited budget, the low level of persons who work for household survey investigation, the uneven quality of statistics, and investigators at the same time, very few people are integrated by government authority and have been contacted with the household survey. Therefore household survey work, though important, but the residents seldom pay attention to household survey work. Some residents do not cooperate with household survey work, and even false data on household income and other sensitive problem, the household survey work to bring very great distress. It is difficult to guarantee the accuracy of household survey data results.With the further development of the information revolution, the accuracy of data has attracted more and more attention by the social. Especially for companies and countries, the impact of the accuracy of the data are often decisive, household survey data accuracy is low can seriously interfere with overall policies making. It is related to the provinces, municipalities and the effectiveness of the national government to make relevant policy, also deeply affect the social market economy of all kinds enterprise marketing strategy formulation and strategic planning, also relates to the statistics department and the government credibility. Therefore, according to household survey work situation in our country, the accuracy of the result of the household survey data of theoretical research on evaluation methods targeted, and expand the corresponding empirical analysis work, has the important practical significance.Specific research process, this paper put on the existing research results of data quality assessment, the basic theory and evaluation method are analyzed in depth and summarized. Data quality evaluation standards in constantly update, now including the accuracy, timeliness, availability and consistency and so on several big evaluation dimensions. But by combining practice, this article analysis found that the present stage based on the characteristics of the household survey statistics, the most should attach importance to and has high maneuverability is quantitatively evaluated in view of the data accuracy.Secondly, the system summary introduces the existing general data about the accuracy of the evaluation of qualitative and quantitative methods, analyzes in detail the practicality and advantages and disadvantages of all kinds of evaluation methods.Third, this article from the Beijing municipal bureau of statistics website, xinjiang autonomous region bureau of statistics website, and the national bureau of statistics web site query by household survey work to get the data reflect the residents’ living conditions, choose the most important per capita disposable income, per capita spending data and data of the deposit to the data as the research object has carried on the empirical analysis of the data accuracy assessment. Empirical analysis conclusion is Beijing municipal bureau of statistics (NBS) and the national bureau of statistics released by the household survey data in general is true, the accuracy is high; Xinjiang household survey of the accuracy of the statistics there may be a bigger problem, family per capita income and other sensitive index of data is false phenomenon.Finally, according to the empirical study to evaluate the effect summarized a set of specific practices in the household survey data accuracy assessment of feasible scheme, for the country’s household survey data accuracy in the overall evaluation. And analyzes the limitations of this study, based on data accuracy evaluation of research, put forward from the Angle of multi-dimensional comprehensive evaluation of household survey data quality, data accuracy assessment for other statistical scholars provide specific reference, and the evaluation of the quality of research work.
