The number of dwellings and dwellings completed in the year demonstrates trends in the housing market supply over time.

The Organisation for Economic Co-Operation and Development (OECD) Affordable Housing Database publication includes the total number of dwellings and the rate of dwellings per 1,000 inhabitants, as well as the number and proportion of dwellings for which building was completed and the dwelling was ready to be occupied in a given year, in OECD countries. A dwelling is defined as a room or suite of rooms and its accessories in a permanent building or structurally separated part there of which is intended for private habitation. Data on the stock of dwellings are mainly drawn from statistics at a national level and cross-country comparisons should be undertaken with care.

OECD data are also used in the following dashboard menu options: Social rental housing stock (OECD), Household tenure (OECD), Home ownership (OECD), Housing prices (OECD), Housing costs (OECD), and Homelessness estimates (OECD).
