Executive summary:

This paper describes new sub-national New Zealand population measures that have been developed by The Treasury using integrated administrative data. The new measures have been made available in an interactive online form in the Treasury’s Insights tool. The paper describes the development of the new measures, compares them against existing sources of official population data, describes some high level findings, and presents three case studies describing population change in specific territorial authority areas.

This paper builds on the framework and results presented in The Treasury’s Living Standards Framework (LSF) Dashboard and the accompanying Analytical Paper “Our people - Multidimensional wellbeing in New Zealand” (McLeod 2016). It profiles people with low mental health wellbeing, using the five General Social Surveys (GSS) from 2008- 16 and other datasets in Statistics New Zealand’s Integrated Data Infrastructure (IDI). The research questions addressed are:

• Which demographic groups have higher rates of low mental health wellbeing?
• Which wellbeing indicators are most closely associated with low mental health wellbeing?
• What is the multidimensional wellbeing profile for users of mental health services and other government services?
• Which people with low wellbeing for mental health are less likely to access mental health prescriptions and referrals?
