Household crowding by ethnicity in Porirua City, New Zealand

The equivalised crowding index applies the concept of the adult equivalent. The formula weights each individual who is in a couple relationship as one half, as well as children aged under 10 years (Morrison, 1994). This gives an equivalised number of people per bedroom. Any value in excess of 1.0 represents a measure of crowding. The formula is:

Crowding Index = [(1/2 number of children under 10 years) + (number of couples) + (all other people aged 10 years and over)] / number of bedrooms

Blank spaces represent nil or zero or the figure too small to be expressed. The figure was suppressed if there were fewer than 50 in the subject matter population of the area. Owing to rounding percentages do not always sum to 100 percent.All cells in this table have been randomly rounded to base 3 prior to calculations. 2001 figures were revised to ensure maximum comparability with previous years (16/5/2003)
