Hello, and thank you for visiting our National Statistical Portal site. Now, let’s take a look at the meaning of national statistics together. 

First, to understand national statistics, it is necessary to examine the types of statistical systems. Statistical systems can be broadly divided into centralized and decentralized systems. Each country adopts and operates an appropriate system based on its historical context and political background. 

A centralized statistical system is one where all statistical activities of a country are concentrated in a specialized institution that measures all statistics needed in various fields. Currently, countries like Canada, Sweden, Finland, and the Netherlands have adopted this type of statistical system. 

On the other hand, a decentralized statistical system is one where statistical activities are distributed among various institutions, and each institution independently compiles the statistics it needs. This system is currently adopted by countries such as the United States, the United Kingdom, Japan, and Taiwan.

Our country's statistical system can be described as a decentralized statistical system. In adopting this decentralized statistical system, we have the National Statistical Office as the central statistical agency. The National Statistical Office is responsible for coordinating statistics to prevent duplication of statistical production among various statistical agencies, enhance reliability, and maintain statistical quality. To produce important basic statistical data for the nation, the National Statistical Office conducts various survey activities, including the complete enumeration census and industrial census. It also carries out sample surveys, such as the annual sample surveys for mining/manufacturing statistics and transportation statistics, as well as construction industry statistics. Additionally, for monthly sample surveys, it conducts the economically active population survey, household survey, mining and manufacturing activity survey, service industry activity survey, and consumer price survey. Besides these, it also prepares analytical statistics.

The comprehensive index of the economy, life tables, and social indicators of Korea fall into this category. Through various types of statistical surveys, the major national statistical information that has been selected, compiled, and processed is constructed in the form of a database and is provided through the internet communication network, managed by the National Statistical Portal site. Additionally, the Statistics Korea nurtures statistical professionals through the Statistical Training Institute and conducts various educational training sessions and research on different statistical methods to help foster a correct understanding of statistics. Now, let's take a look at the precious national statistics that Statistics Korea is responsible for, and the process of creating them. As you can see, the national statistical approval process begins with the submission of the approval application and continues through to the input of the statistical adjustment database, leading to the planning and design of the statistical survey. At this time, the scope of the survey, survey items, survey methods, and survey targets are determined, and the survey form is prepared.

Additionally, we will prepare administrative support measures such as data processing methods and budget estimates. After conducting preliminary surveys, training for statistical investigators, and promoting the statistical survey, we will commence the full-scale collection of statistical data. Investigators will obtain information from the survey subjects and record it on the survey forms. The survey manager will oversee the field investigations while simultaneously collecting and reviewing the completed survey forms. 

When the actual survey is conducted through in-person interviews, the investigators must clearly identify themselves and explain the purpose of their visit to help the respondents understand. It is essential to ensure that respondents are aware that the information obtained through the interviews will be kept confidential, which will help us gather accurate and reliable statistical data. The statistical data collected through this survey will undergo data processing, starting from reviewing the information on the survey representation to compiling statistical tables, ultimately producing objective and usable statistical tables.

To accurately convey facts and effectively present information, it is essential to ensure that the data is well organized. Statistical tables are one of the most commonly used methods of data organization. Once the organization of the data is complete, national statistical information will be provided to stakeholders through statistical publications or the national statistics portal site. The provision of data through the statistical database allows for easy understanding by enabling the search, classification, and re-analysis of statistical data. The Statistics Korea is committed to providing a user-centered statistical service that designs the future of South Korea.
