Methods - how we monitor

Where and how we collect the data

Monitoring sites

The data were collected across New Zealand by Statistics New Zealand1 as part of the Census of Population and Dwellings. The purpose of the Census is to collect demographic and social statistics, which can be used by Government, business and community organisations for planning and other decision making.

Monitoring frequency

This indicator is usually updated every five years after the results of each Census are published. There census that was supposed to occur in 2011 was delayed until 2013 due to the Canterbury earthquakes. The next Census is due in 2018.

Monitoring history

Census information on the population growth is easily available for the period 1991-2013 from Statistics New Zealand. The period between the 2006 and 2013 census was 7 years instead of the usual 5 years.  

Measurement technique

The Population Census is a self-administered hand-delivered questionnaire carried out every five years. Statistics New Zealand tries to cover all people in New Zealand on Census night. Data are entered into a national database and rounded to ensure anonymity. Data are summarised into various levels including national, regional and territorial authority.

How this indicator is compiled

  • Data for the Waikato region for 2001 to 2013 were sourced from Tables 1 and 1b of Statistics New Zealand’s Census 2013 Regional Summary.
  • Data for 1991 and 1996 were sourced from the 2001 Regional Summary.
  • For the Waikato region population totals data were used directly from the table.
  • The per cent changes for the Waikato region, New Zealand and our region's districts were calculated as:

           Per cent change = Population 2013 – Population 2006 x 100
                                                      Population 2006
