Residential Construction tracks the actual construction (not sales) of housing and is part of Gross fixed capital formation. GFCF consists of resident producers' acquisitions, less disposals, of fixed assets during a given period plus certain additions to the value of non-produced assets realised by the productive activity of producer or institutional units. The GDP used in denominator of the MIP indicator comes from the ESA 2010 transmission programme.

Private consumption expenditure consists of expenditure incurred for the direct satisfaction of individual or collective needs by private households or non-profit institutions serving households (such as religious societies, sports and other clubs, political parties, etc.).

The annual building permits data are business cycle indicators providing information on the development of granted building permits in one year. Builders apply for building permits and local building administrations issue them normally before the beginning of the construction work. Therefore building permits are considered as a leading indicator of the creation of new residential buildings. The data cover the permits for all types of residential buildings (including residences for communities).

The data are expressed in square meters of usable floor area per 1000 inhabitants.
