The number of one-person households has been growing steadily over the last decade. An increase in divorce rates and people marrying later in life mean more people are living alone.
One-person households tend to increase with age. As people age, children leave home and older people are more likely to live alone. There is also a preference for ’ageing in place’ and an increasing delivery of care in the home that reduces the number of people moving into retirement homes (Statistics New Zealand (1998), "New Zealand Now: Housing", Wellington, pp.48–49).
In 2006, 23.0 percent of households were one-person households. In the Buller District the figure was 31.6 percent, the highest for any territorial authority in 2006. Manukau City had the lowest proportion of one-person households at 14.2 percent while Tasman District was closer to the total New Zealand figure at 22.9 percent.
