Statistical System of Japan

Statistical Organizations of Japan

The statistical system of the Japanese government is decentralized, in that, while the Statistics Bureau (SBJ) conducts fundamental censuses and statistical surveys, other relevant ministries produce statistics for their own policy purposes.
Under this decentralized system, it is generally difficult to maintain consistency in statistical activities among different ministries, and to avoid duplication in the compilation of statistics. Therefore, the Director-General for Policy Planning (Statistical Policy) (DGPP-SP) is responsible for coordinating the statistical activities of different ministries.

Point of Official Statistical System

Statistical Surveys Conducted by National Administrative Organs

Statistical surveys request individuals, juridical persons or other organizations to report facts for the purpose of producing statistics.
Statistical surveys conducted by national administrative organs are divided into two categories: "Fundamental Statistical Surveys" conducted to produce "Fundamental Statistics" and otherwise "General Statistical Surveys. "Statistical surveys conducted by the national administrative organs undergo individual clearance through the Minister for Internal Affairs and Communications with a view to reducing the reporting burden by eliminating duplication among statistical surveys.

Fundamental Statistics

Among the statistics produced by the administrative organs, especially the important ones are identified as the Fundamental Statistics and developed systematically. The Fundamental Statistics are defined by the Statistics Act as follows:

• Population Census
• National Accounts (SNA)
• Statistics that are or are to be produced by administrative organs and are designated by the Minister for Internal Affairs and Communications as those falling under any of the following:

• Obligation to report
• Prohibition of impersonating Fundamental Statistical Surveys
• Affairs undertaken by local public entities

Confidentiality of Personal Information on Respondents of a Statistical Survey

Persons who are officially engaged in handling of questionnaire information and trustees of statistical surveys have a duty that they shall not divulge any confidential information of the respondents that may have come to their knowledge in the course of duties. Those who violate the prohibition are sentenced to imprisonment for not more than two years or a fine of up to one million yen.

Production of Fundamental Censuses and Statistical Surveys

SBJ's Mission and Principles - As Central Organization of Official Statistics -

Statistics is necessary for the administration and the decision-making of companies as an "information platform for society."
We systematically develop and disseminate relevant and reliable statistics which meet the needs arising from socioeconomic changes, and provide them in a timely and proper manner. We aim to support the planning, formulation and evaluation of governmental policies, and assist in rational decision-making by individuals and businesses.
Moreover, we strive to contribute towards the improvement of people's lives, and development of the society and economy.

Production and Provision of Fundamental Censuses and Statistical Surveys

List of Statistics Produced by the SBJ

The SBJ plans and conducts the important statistical surveys of Japan, and prepares and provides accurate statistics that are beneficial for society, by responding adequately to socioeconomic changes in our country.
The representative examples are the Population Census and the Economic Census.
These two are complete censuses where the entire population is surveyed

The results withstarmarkare reported monthly at the Cabinet meeting by the Minister.
Underlined are the fundamental statistics.
*1 Except the years in which the Economic Census for Business Activity is conducted
*2 Prior to 2019, the survey was conducted as the National Survey of Family Income and Expenditure

Flow of Statistical Survey

Production of Statistics

Major methods of statistics production include the method mainly based on statistical survey, method to tabulate materials held by government agencies, and method to estimate by processing and calculating other statistics and data. Statistical survey is produced in the SBJ basically following the flow as shown below.

Planning and designing surveys and maintaining the implementation systems

Survey items, methods, and processing are examined according to the features and purposes of surveys, to formulate survey plans and to prepare documents and design systems necessary for implementing surveys. Survey implementation systems such as the arrangement of enumerators are also established.

Field survey

In cooperation with local governments and enumerators, identifying respondents, questionnaires are distributed and requested to be filled out, and collected and examined during the designated period and in accordance with the designated method.

- Role and Importance of Enumerators -

In conducting the statistical survey, it is very important for us to accurately grasp respondents (survey targets) and to have them fill out questionnaires correctly. The enumerators get survey cooperation by visiting the survey area to grasp the survey targets (respondents), meeting the people to be surveyed face to face, and explaining the purpose of the survey and how to fill out questionnaires. Through such cooperation between the enumerators and local governments, the statistical survey is conducted smoothly.

Data processing

The submitted questionnaires are delivered from the SBJ to the NSTAC, then are processed after checking the data quality by converting the questionnaires into data, coding based on the stipulated classification criteria, checking and investigating the data, and tabulating and validating the statistical tables.

Publication

The processed results are analyzed and published by SBJ. The survey results with a summary of the results and statistical tables are provided through the internet.
