Building production data is of high interest to the public and is closely related to the economy, culture, society, population, etc., of a country or region. In particular, the output of buildings is considered important, as it reflects the economic dynamics of the construction market. As such, South Korea collects and distributes data related to building production as statistics under the Building Act and other relevant laws.

However, the statistics currently available are mere summaries, e.g., the area and number of buildings, with which it is difficult to understand intuitively the building production and grasp the current situation. In particular, statistics on building production are of high interest to the public, and there is a need to improve building production statistics in order to establish effective data-driven building policies. Doing so requires developing a statistical index to monitor the current situation of the building industry and view it in comparison to other sectors or over time, rather than simply providing figures. In addition, such an index should be provided in a form that is standardized and easy for users to understand. In other words, it is necessary to develop building production indices that allow the intuitive understanding of building output and determine the causes of changes in building output in comparison to statistical indices and indicators in other sectors.

The purposes of this study are to 1) develop building production indices that allow for comparison between different points of time and comparison to other indices and indicators and produce a pilot index, 2) use the pilot index for comparative analysis with other indices and indicators such as economic and demographic indices, and 3) prepare measures for sustainable production and publication of the building production indices.
