Population by age group in Hamilton City, New Zealand

The census usually resident population count of New Zealand is a count of all people who usually live, and are present, in New Zealand on a given census night. This count excludes visitors from overseas and excludes residents who are temporarily overseas on census night.

This data has been randomly rounded to protect confidentiality. Individual figures may not sum to totals and values for the same data may vary in different tables.

Census counts are not directly comparable with other published population estimates. The estimated resident population is higher than the census usually resident population count because the estimates make an allowance for net census undercount and residents who are temporarily overseas at the time of the census. They also have a different reference date – 5 March for the 2013 Census and 30 June for population estimates.

This time series is irregular. Because the 2011 Census was cancelled after the Canterbury earthquake on 22 February 2011 the gap between this census and the last one is seven years. The change in the data between 2006 and 2013 may be greater than in the usual five-year gap between censuses. Be careful when comparing trends.
