The Economic Statistics Meetings and The Reading and Discussion on surveys were held on a regular basis. Three themes were studied through these meetings: (a) Missing in censuses were reviewed using Economic Census and Census of Commerce; (b) A model for stratum jumpers based on small-area estimation was developed and presented at Japanese Joint Statistical Meeting 2012. Quantile estimation under doubly protected hot deck imputation was studied through simulations and presented at Joint Statistical Meeting 2013 in Motreal as an invited paper

We conducted extensive micro data analysis using several sets of official statistics. Our research covered household classification, database construction for dissemination, analysis of "Survey on Time Use and Leisure Activities", etc. We presented some of our findings at several academic meetings, and published some papers in journals.

We studied use of auxiliary variables to provide accurate official statistics given statistical resources. In particular, we proposed doubly protected regression random imputation, compared four bootstrap methods for stratified three-stage random sampling through simulation, and examined the structure of questions in the U.S. Economic Census. The results have been presented at the annual joint statistical meeting in Japan and published in refereed journals.

The 5th Japan's Artists Survey was conducted to construct the total database including the four rounds surveys conducted during the past twenty years. Artists' annual income was analysed by their household patterns. The results were published at several academic meetings both in Japan and overseas. The use of ten percent sampled micro data of Japan's Population Census from 1985 to 2005 was granted just before the final project year. We constructed its database, and finished the initial data processing by the household patterns

Throughout our research period in the past two years, we regularly held seminars once or twice a month. Besides the project memebers and a few graduate students, official statisticians from divisions of the government joined our seminar. The main results we obtained are as follows :1. Most members of the project participataed in collecting and summarizing previous resarch in the field of sampling from the finite population, mostly in the field of economic surveys. Our viewpoint was to develop a useful guideline to design new sample surveys, especially those conducted by the government when we take into account the effect of nonresponse explicitly.2. As for statistical analysis of incomplete data, we surveyed actual methods of correcting incompleteness of the data, employed by official statisticians. At the same time, we discussed theoretical aspects of estimation and evaluation of the sampling errors when nonresponse is present.3. The papers presented at the seminar are compiled, so that they are easily available for future studies

A practical problem of economic statistics is divided into (1) collection / processing stage of data and (2) an analysis stage. In particular you must examine reliability about observation when you analyze the micro data. The typical problem is to cope with incomplete data supplementing with external information. In this study, investigate technique to analyze the incomplete data which is supplemented by statistical matching.1. Some theory models and an experiment of statiscal matching based on the government examine statistics to do so, me compare complete matching and statiscal matching and investigate a possibility of disclosure of micro data to the public.2. As examples of incomplete data are missing values, termination of data collection, the curancy, and grouping of continuous data. And aecrecy of the individual information is a kind of incomplete data. In particular, we investigate the processing method of missing values.3. An application of bootstrap method to the case of incomplete data. Suggest a simple non parametric method of bootstrap to supplement incomplete data

WE HAD RESEARCH MEETIGS ONCE A MONTH TO HEAR THE RECENT TRENDS IN STATISTICAL SURVEY FROM GOVERNMENT STATISTICIANS.TO IMPROVE EFFICIENCY IN STATISTICAL SURVEY, INTERNET AND OTHER MAGNETIC DEVICES CAN BE USED TO COLLECT QUESTIONNAIRES FASTER THAN NOW.TO USE COMPUTERS EFFICIENTLY IN STATISITICAL SURVEYS, FOLLOWIG PROBLEMS SHOULD BE EXAMINED FURTHER : (1)TO ESTABLISH COMMON CODINGS SYSTEM BETWEEN NATIONAL AND LOCAL GOVERNMENTS, (2) TO INTRODUCE AUTOMATICAL REPORTING SYSTEM TO FIRMS AND ESTABLISHMENTS.AS FOR MAK1NG STATISTITICAL TABLES EFFICIENTLY, FOLLOWIG PROBLEMS SHOULD BE EXAMINED FURTHER : (1) TO COMPILE AND USE AN OVERALL BUSINESS FRAME, (2) TO USE MICRO STATISTICAL LINKAGE FOR DIFFERENT SURVEYS.INTENSIVE COMPUTER EXPERIMENTS ARE NEEDED TO MAKE AN INQUIRY INTO ABOVE PROBLEMS BY USING DESIGNATED STATISTICS COMPILED BY DIFFERENT MINISTRIES.AS THE USE OF DESIGNATED STATISTICS IS RESTRICTED BY STATISTICS LAW, FURTHER RESEARCH IS NEEDED FROM THE VIEWPOINT OF LAW

(1) We have conducted comprehensive research in order to find out present situations on arts and culture in Japan. There are two major streams in our research ; one is the reuse and re-construction of existing government statistics on arts and culture, and the other is to conduct our own questionnaire surveys on both demand and supply of arts and culture.(2) We also went on a research trip to Australia to collect various kinds of materials on statistical surveys on arts and culture in Australia.(3) We made an analysis on daily time use and activities from the result of SURVEY ON TIME USE AND LEISURE ACTIVITIES.(4) We made an analysis on expenditure for arts and culture from the result of FAMILY INCOME AND EXPENDITURE SURVEY.(5) We made an analysis on arts education from the result of BASIC SURVEYON SERVICE INDUSTRIES.(6) For the last fifteen years we have conducted four periodical questionnaire surveys on (a) professional artists, (b) arts organizations and halls and (c) students demand on art activities. These database are re-organised for easier access, and then made a time-series analysis respectively.(7) We made a basic frame for 'Survey on Art NPO's in Japan' in order to grasp the actual situation of art NPO's

We held 7 meetings on the Japanese official statistics from April, 2002, to January, 2003. There we discussed (a) new regional price indexes in the National Survey on Prices ; (b) theoretical aspects of regional comparisons ; (c) prefecture-based unemployment estimator from the Labor Force Survey ; and (d) a new estimation method in GDP statistics. In particular, we proposed a new resampling method for the National Survey of Prices, which was presented at the annual meeting of the Japan Statistical Society. At the meeting, we also made two presentations on (a) use of micro data from the Family Income and Expenditure Survey and (b) new economic indicators. In 2002, we had no talks on use of IT in Japanese economic statistics at the regular monthly meeting.From April, 2003, to January, 2004, we had 7 meetings on the Japanese official statistics. This time, we discussed use of IT in Japanese economic statistics : (a) use of portable devices on the Retail Price Survey ; (b) IT statistics from the Survey on Time Use and Leisure Activities ; and (c) New Generation Statistics System by METI. At the same time, we continued our research on the resampling method for the National Survey on Prices. Our method was applied to NSP micro data and the results will be submitted to a refereed journal.In summary, we have obtained several satisfactory accomplishments on application of recent advanced statistical theory on surveys. Use of IT, on the other hand, will be studied continuously. We had obtained useful comments and suggestions from our monthly meetings

世帯データを中心として,官庁統計におけるミクロデータの利用可能牲が広がってきている。その中で,今後の広範な研究利用を実現するためには,いくつかの現実的な問題が解決されなければならない。特に,研究上の多様な要望に対応しやすい一次統計データベースの構造を検討すること,さらにミクロデータを提供するためのデータ処理に関わる作業をできるだけ効率的に設計するとが必要である。すでに初年度の研究において,世帯のミクロ統計データに対象を絞って,研究基盤を整備する効果的な条件を検討した。昨年度と今年度の研究においては、その成果に基づいて,家計調査および家計消費状況調査を対象として標本設計に関する詳細な情報を収集し,調査の特性を明らかにする作業を実施した。家計消費状況調査に関しては統計法上の目的外利用の手続きによって,ミクロデータを利用した分析を実施した。現在,その内容の取りまとめ作業に当たっている段階である。関連して,研究者の視点から要求される問題として,ミクロデータを分析する場合に必要なデータに関する情報の整備方法についても検討した。具体的な例としては,個票における欠測値ないし外れ値の発生などの不完全性と,それに対処するための補完ないし外部情報の利用に関する情報がある。世帯データの提供に密接に関連する問題である「統計データアーカイブ」については,諸外国の事例を参照しつつ,わが国の官庁統計に対する課題を検討している

(1)Research Meeting on Economic StatisticsFrom May 2004 to January 2006, we have held 15 regular Research Meetings on Economic Statistics, including three conducted during May 2004 to September 2004, when they were not funded yet. Among the topics were : the first occasion of survey practice by a private survey company in Japan's official statistics ; a new estimation method for the monthly Labour Statistics taking its time series structure into account ; the new survey on small- and medium sized firms in Japan ; use of resampling methods and density estimation in the National Survey of Prices ; Economic Census in Japan ; and Business Register in US and UK. Particularly, we organized a registered session entitled "Reforming the Official Statistics System in Japan" at the Joint Statistical Meeting 2005 in Japan. Two key note speakers (Mr. Tatsuo Inoue and Professor Yoshiro Matsuda) and two discussants (Professor Hideo Fukui and Professor Kei Takeuchi) were invited to the session and many researchers and official statisticians participated to discuss.(2)OutputSaigo and Sitter (2005) proposed a residual-rescaling jackknife variance estimator with re-imputation for randomly imputed survey data. Yoshizoe (2005) discussed economic statistics in Japan in a historical perspective. Hiromatsu, et al. (2004) and Katsuura (2005) studied combination of multiple statistics for empirical analyses.In addition to articles appearing journals and books, we made several presentations at the Joint Statistical Meetings 2005 and 2006. Among them were : Research on Statistical Matching using Japan's Household Survey (by Yoshizoe) ; A Bootstrap Method for Two-Phase Sampling (by Saigo) ; Use of kriging for interpolating Tokyo's land prices (by Saigo and Masunari) ; and Effects of changes in questionnaire on survey outcome-An empirical study on Survey on Time Use and Leisure Activities (by Katsuura). Some of them are submitted for publication in research journals

This research issues related to the official statistics, this research was focused on issues directly related to improvement of the current survey method and also wide-range utilization of the survey results, and was intended to present theoretical solutions.The actual research activities were carried out jointly with other research groups Research meetings were held about once every fiscal year, and exchanges of opinions were carried out with researchers in peripheral regions and staff members from various government agencies involved with official statistics. The results of the research were announced by academic societies and other bodies in fields related to official statistics, such as the Japan Statistical Society.Along with the death of Satoru Kanoh (professor at the Institute of Economic Research, Hitotsubashi University)who planned this research, the research representative was replaced with Inaba in the final fiscal year. Kanoh configured this research organization after arguing that theoretical study concerning official statistics was an urgent research issue and that it was necessary to carry out total research on mutually related research topics. In May 2007, the Statistics Law was amended, and stipulations covering the provision of statistics by tabulation carried out under contract and the provision of survey sheet information concerning the measures to guarantee anonymity were newly enacted. The contents of these stipulations are directly related to the issues of this research, enabling the foresight and importance of this research planned by Kanoh to be confirmed. We believe that in order to use the results of this research for the disclosure and utilization of official statistics, it is necessary to carry out exchanges of opinions with various government staff members to a greater extent than before, and it is also desirable to carry out further research based on the results of these exchanges

During the term of this project(ie., April, 2006-March, 2008), we had had 13 meetings on economic statistics(Economic Statistics Research Meetings, ESRM henceforth). Among them are : Use of the Japanese Population Census as a micro data(June, 2006) ; Use of private statistics for the Business Frame in Japan(October, 2006) ; Use of information from the National Tax Agency in the Japanese official statistics(May, 2007) ; Preparation of 2010 Population Census(October 2007) ; Recoding of and Access to US Population Census(October, 2007) ; Reforming the Japanese Statistical Law and data archive in the future(November, 2007) ; and Data archive in UK(November, 2007). In addition, we discussed nonsampling errors and panel surveys both of which are particularly useful for reuse of micro data through data archive. Moreover, we had two notable conferences jointly with the Japan Statistical Society : entitled The Japanese Official Statistics in the Future (September 2006, Tohoku University) and The Current Situation and Future Challenges of the Japanese Official Statistical System (September, 2007., Kobe University). Both of the conferences gathered more than 100 participants and provided useful keynote speeches and discussions about the rapidly changing Japanese official statistical system.Other than these 13 ESRMs, we had published 29 papers and made 10 presentations during April, 2006 to March, 2008
