Microdata Integrated Service

Statistics Korea not only collects microdata of self-produced statistics, but also collects microdata of other statistical agencies such as government departments, local governments, and research institutes in one place, so that people can conveniently use various statistical data through MDIS.

Microdata : data on the characteristics of units of a population, such as individuals, households, or establishments, collected by a census, survey, or experiment.

Service Promise: We endeavor to perform to the highest of standards to ensure that the value of the economic and social data we hold can be maximized. Under the Statistics Act we have a legal duty to protect any information we collect from users.
