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 1,965 in fiscal 2010, and were funded by the MIC.
By contrast, few municipalities have a statistical division. The personnel engaged in statistical work numbered 8,634 as of April 2010, 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 two representative methods of collecting data: mail and enumerators. 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.
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
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.
In case of a large census/survey, pilot surveys are conducted to check the suitability of the questionnaire and the survey methods.
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.
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.
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.
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.
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.
