Redundancy, omission of statistics and inconsistency between statistics compiled by various agencies may occur under a decentralized system.

One of the major functions performed by KOSTAT is to provide the statistical data for a variety of users such as policy-makers, governmental planners, administrators, researchers at research institutes, universities, political parties, enterprises, individuals, etc. The provision of statistical data is made through various means of publicity such as publications, CDs, on-line database system(KOSIS), Statistical Datawarehouse system, MDSS(Micro Data Service System), tabulation for special requests, etc.
Statistical Quality Assessment
A statistical quality assessment system, which is, now in place in Korea can be summed up as a combination of the statistical inspector system and the quality assessment checklist scheme. Since the revision of the Statistics Act in 2007, the rotational assessment and self-assessment are being carried out every 5 years and every year, respectively.
Statistical Training and Research
The Statistical Training Institute (STI) trains annually around 3,600 persons from both governmental and non-governmental agencies. Its training curriculum includes several courses on basic and advanced statistics, sampling technique, computer technology, survey methodology, etc.
The Statistical Research Institute (SRI) has contributed to the advancement of National Statistics through statistical research and development. The SRI conducts research projects required to develop new statistics and statistical techniques to improve the quality of national statistics. It also conducts in-depth analysis of statistical data.
International Statistical Cooperation
KOSTAT actively participates in international and regional conferences as well as projects on statistics. KOSTAT hosts international conferences on statistics and related fields. In addition, KOSTAT regularly receives statistical obligations and sends its work-results to international organizations and other countries.
