Occupancy rate is the total number of occupants usually resident in private dwellings divided by the total number of occupied private dwellings. This gives the average number of people per dwelling or simply the average household size.
This definition relates only to people who usually reside in private dwellings, hence visitors are excluded.
The occupancy rate describes the relationship between New Zealand's housing stock and the changing social structure.
For the last three censuses, Manukau City recorded one of the highest occupancy rates of any territorial authority while the Thames-Coromandel District had consistently recorded the lowest until 2006 when it was overtaken by Buller District.
In 2006, the national occupancy rate was 2.7, marginally lower than in 1996 (2.8). Manukau City had the highest occupancy rate at 3.4, while the Buller District had the lowest at 2.3.
