This webpage gives you information on how to use Healthspace, and explains frequently used statistical terms used on this website.
What is Healthspace?
What is available in Healthspace?
Healthspace gives you access to regional health and population data for New Zealand. You can explore regional data in two main ways:
- Map display: You can look at a single indicator across all regions, and compare between regions.
- Local area report: You can view all indicators for a health topic for an individual region in one place.
What are Healthspace map displays?
The interactive map displays allow data for a selected indicator to be displayed on a map, bar graph and time series graph at the same time. Indicators are presented at a range of regional levels, including:
- district health boards
- territorial authorities (city and district councils)
- regional councils
- Auckland local boards
- area units.
What are Healthspace local area reports?
Local area reports let you explore indicator data for a selected region and New Zealand. All indicators for the health topic are displayed, mostly as tables and graphs. Currently, these are only available for the Alcohol-related harm topic.
How do you use Healthspace?
We recommend you use Google Chrome or Firefox Mozilla web browsers.
To use Healthspace, select a Health Topic from the homepage, or from the drop-down menu. Scroll down the page, and select a map display to explore.
In the map display, use the drop-down boxes to select individual indicators and other options, such as the time period. Click on a region on the map or table to see the time series for that place and see it highlighted on the bar graph. Multiple areas can be highlighted at one time.
To zoom in and out of the map, hover over the top of the map to bring up the control panel, and use the + and – magnifying glass icons to zoom in and out. You can move the entire map by holding down the left mouse button and then moving the mouse.

Statistics and methods
What are crude and age-standardised rates?
Rates for health outcomes on Healthspace are presented as either crude rates or age-standardised rates.
Crude rates represent the proportion of the population affected. They are calculated by dividing the number of people affected, by the number of people in the population.
Age-standardised rates take into account the age structure of the population, and are used to compare statistics between different populations.
What is a confidence interval?
A confidence interval gives the range that the true value is likely to fall within. Generally, 95% confidence intervals are presented on Healthspace.
For survey data, 95% confidence intervals give the range that if we selected 100 different samples, we would expect the prevalence value to fall within the range 95% of the time.
What is the difference between prioritised ethnic groups and total response ethnic groups?
Prioritised ethnic groups assign people who reported multiple ethnic groups to only one ethnic group, in the prioritised order: Māori, Pacific, Asian, European/Other.
Total response ethnic groups include everyone who identifies with that ethnic group. This means that the sum of the ethnic group populations will be greater than the total population.
