   The Survey Planning Division coordinates the activities of the Statistical Survey Department. It is also responsible for executing and tabulating statistical surveys entrusted by other national administrative organizations and local governments. Furthermore, it is responsible for technological and methodological research and studies on statistics, compiling derived statistics such as Social Indicators, as well as the overall coordination of statistical surveys within the MIC. The Geographic Information Office belongs to this Division, and is charged with preparing and using geographic information, as well as being responsible for grid-square statistics and the Census Mapping System (CMS). The Director for Information Processing is responsible for planning and researching the information processing systems used for tabulation. The Director for Statistical Classification and Commodity Specification is responsible for establishing standards for applying statistical classifications, and research on commodity specifications.


   The Population Census Division is in charge of executing and tabulating the Population Census, and the Housing and Land Survey. It also compiles current population estimates and internal migration statistics. The Labour Force Statistics Office in this Division is responsible for statistical surveys on employment and unemployment such as the Labour Force Survey and the Employment Status Survey, and the Survey on Time Use and Leisure Activities.

The Price Statistics Office of this Division is responsible for the Retail Price Survey, the National Survey of Prices [1967-2007], and the Consumer Price Index.

5. Field organizations and collecting data

   Although the Bureau conducts various censuses and statistical surveys, it has no field organization of its own. Instead, its field activities are conducted through the statistical organizations of local governments.


   The statistical organizations of the prefectural and municipal governments play an important role in supporting Japan’s statistical system. They are solely responsible for collecting data for central government censuses and other large-scale surveys such as the Population Census, the Census of Manufactures, and the Establishment and Enterprise Census [1947-2006]. Furthermore, at their own discretion, they conduct independent surveys according to their needs, develop local statistics, and improve the use of statistics within local administrations.


   At the prefectural level, to fulfill its data collection responsibilities for the central government censuses and statistical surveys, each prefectural government has a statistical division staffed with statistical personnel. These statistical personnel in all prefectural governments numbered 1,930 in fiscal 2013, and were funded by the MIC.


   By contrast, few municipalities have a statistical division. The personnel engaged in statistical work numbered 8,068 as of April 2013, but in many cases they have other responsibilities besides statistics. The expenses for municipal personnel engaged in statistical work are covered by the Local Grant Tax System of the central government.


   Generally, there are representative methods of collecting data: mail, enumerators and response via the Internet. In Japan, many censuses and statistical surveys employ enumerators, taking into consideration factors such as response rate and accuracy. The enumerators are public servants, who are appointed on a temporary basis for the respective censuses and statistical surveys.


Production of statistics

   Censuses and statistical surveys are planned and conducted, and the results are compiled, released, and published according to the following flowchart:


Flowchart of census/survey-taking - from planning to publication

Overall planning of census/survey-taking and establishment of organizations (Statistics Bureau)

(1) Preparing questionnaires (survey items), and deciding on survey methods, statistical tables, etc.

   Given the purpose and characteristics of a census/ survey, the survey items to be covered, survey methods to be employed, and statistical tables to be produced are considered and determined, and questionnaires and other documents are designed accordingly.


(2) Conducting pilot surveys

   In case of a large census/survey, pilot surveys are conducted to check the suitability of the questionnaire and the survey methods.


(3) Preparation of census/ survey documents, and establishment of organizations

   Manuals for census/ survey-taking, letters requesting cooperation, instructions on how to answer questions and other necessary documents are prepared. At the local level, enumerators and supervisors are selected and appointed, thus establishing the census/ survey organizations.


(4) Instruction/orientation for local governments and enumerators regarding the census/ survey-taking

   The Bureau and local governments hold a series of meetings to instruct and explain the census/ survey-taking process to local government officials and enumerators, especially fieldwork aspects, including the distribution and the collection of questionnaires.


Fieldwork (local governments and enumerators)

(5) Listing and contacting respondents, and distributing and collecting questionnaires

   Enumerators make a list of all the respondents they are to cover and contact, distribute questionnaires, request the cooperation of respondents, collect the completed questionnaires, and submit them to prefectural/municipal governments. This work is to be done during the designated period and in accordance with the designated methods.


(6) Examining completed questionnaires and other documents, and submitting them to the Bureau

   The prefectural and municipal governments conduct a series of checks to ascertain whether or not the submitted questionnaires and other documents have any deficiencies in their content, and in due course the prefectural governments submit them to the Bureau.


Receipt of questionnaires and other documents (Statistics Bureau)

(7) The Bureau receives questionnaires and other documents, and issues official acknowledgment to the prefectural governments.


Data-processing (National Statistics Center)

(8) Data contained in the questionnaires are processed by the Center to produce statistical tables.(See box)


Publication (Statistics Bureau)

(9) Releasing and analyzing results, and publishing reports

   Census/ survey results, which have been produced and certified by the Center, are analyzed by the Bureau, and a summary is released to the public as an advance report as promptly as possible. The final reports and electronic media such as CD-ROMs and MOs containing the results of the census/ survey are compiled later and distributed to the central, prefectural and municipal governments as well as major university libraries, etc., so that users can access them. The reports, including electronic data, can be purchased through the Government Publications Service Center and non-profit organizations.


Flow of census/survey-taking



Processing census and statistical survey data

    The questionnaires and other documents of various censuses and statistical surveys are processed by the National Statistics Center. The Center is responsible for processing the data collected by the Population Census and other fundamental censuses and statistical surveys in the country, as well as for research on essential statistical technology that is closely associated with this data-processing work. The Center thus aims to ensure the reliability of statistics and contribute to the development of statistical technology.

    The process for producing statistics from questionnaires collected in censuses and statistical surveys sent to the Center generally consists of procedures such as (1) registering and storing questionnaires, (2) inputting data, (3) coding entries, (4) editing data, (5) data processing, and (6) certifying the statistical tables produced.

General data-processing procedures

Flow of census/survey-taking

(1) Registering and storing questionnaires

    Upon receipt of questionnaires and other documents from central or local governments, the Center checks whether any are missing or duplicated; divides the documents into groups of a certain size, and places them in storage rooms that are specially designed for safekeeping.

(2) Inputting data

    The questionnaires are fed into optical character readers (OCRs) or keyed into computers.

(3) Coding entries

    Entries in the form of phrases or sentences are converted into alphanumeric codes according to certain classification standards such as industrial, occupational, and income and expenditure.

(4) Editing data

    Entries in the questionnaires are examined for duplication, omissions or invalid entries, and are corrected, if feasible. In addition, after coding the entries, all input data are checked thoroughly by computer for validity and consistency. Any errors detected are either corrected by computer, or edited by keyboard entry, referring to the original questionnaires.

(5) Data processing

    Clean data thus obtained are processed to produce statistical tables.

(6) Certifying the statistical tables

    The statistical tables produced are examined by computer in accordance with pre-programmed procedures to check for any inconsistencies within each table and among tables (automatic examination). Major figures are also analyzed, by comparing them to past figures and related statistics. Statistical tables are thus certified by the Center, and then submitted to the Bureau.
