Possible to manipulate the data, produce tabulations and undertake statistical analyses to individual specifications

Ideal for learning to use census data

Statistics NZ is investigating the possibility of producing more census CURFs in the future. Products and services for the 2011 Census have not been finalised.

We would be interested on your input on the need and use of a Census CURF

2008 New Zealand General Social Survey

Background The NZGSS provides data on important social and economic

outcomes of New Zealanders that is not available from other sources

The NZGSS will be used to:

Monitor progress over time and track the impact of events such as the current recession

Identify the factors associated with multiple poor outcomes

Provides new information about how people think they themselves are faring, which complements objective information

Allow international comparisons with other OECD nations

Investigate new topics in a timely manner

Scope and Content

Human Rights

Culture & Identity

Leisure & Recreation

Social Connectedness

Safety & Security

Knowledge & Skills

Physical Environment

Overall Life Satisfaction

Paid Work

Economic Standard of

Living

HousingHealth

Support Across

Households

First results from the NZGSS were released on:

29 October 2009 at 10.45 am

First major new survey funded under the Programme of Official Social Statistics (POSS)

New Zealand General Social Survey

Key Messages: what is the NZGSS?

The NZGSS is one of three regular household surveys run by Statistics New Zealand (the others being the HES and the HLFS)

Nationally representative sample of 8721 households

Biannual (survey runs April – March)

Face to face computer assisted interviews

Respondent is one household member aged 15 years or over

Dissemination and Data Access

NZGSS is funded as part of the Programme of Official Social Statistics (POSS)

POSS represents a major investment by government in the evidence base for policy

POSS depends entirely on use of the data collected to inform policy and promote greater transparency in monitoring outcomes


Statistics New Zealand:

Provides the dataset

Publishes tables containing the most important aggregate statistics

Undertakes a limited amount of analysis

Supports users without strong analytical capability themselves

But to get full value from the NZGSS it needs to be used more widely…


We are keen to facilitate access to the NZGSS via:

Secondments to Statistics New Zealand for joint work
