Accessing Data from the Australian Data Archive
Accessing data in ADA may involve any of the following stages:
- Finding studies and variables
- Viewing study and variable information
- Analysing data
- Downloading data
For more information on how to access ADA data, you can also read ADA User Guide No. 2, Accessing Data from the Australian Data Archive (PDF).
1. Finding Data
There are two methods for finding data in the Australian Data Archive.
- Browse the ADA Data Catalogue
- Search for data using the search box above
Searching or browsing from within one of the ADA subarchives will automatically limit the results to data from within that subarchive. At any time during a sub-archive search, you can expand your search by selecting the "Expand this search to all ADA" link in your search results.
You can also save your searches to return to later. Click on "Save this search" in your search results to save the search expression. You can then access these saved searches from your account section at the top right of every page.
2. Viewing study and variable information
Once you have located data you are interested in, you can find out more about the data by exploring the Study Page. Here you will find information on who conducted the study, data collection and methodology, access conditions, variables in the study, and related information (such as questionnaires, reports and other information). From here you can also access the Nesstar online analysis and request to download the data from the study.
3. Online analysis
From the Study Page, you can access the Nesstar online analysis system, to run analysis of the data you are interested in online. To analyse data, simply click on the link to "Analyse or Download this data in Nesstar" at the top of the study page. This will open the Nesstar system for you. If you would like to conduct detailed analysis of the data (using the Nesstar tabulation and analysis tools) you will need to register with ADA, and login using your ADA username and password. Note that if you would like to analyse data that has restricted access conditions online, you will need to complete a Restricted Data Access request.
More details on using the Nesstar online analysis and download system are available in the ADA User Guide No. 2, Accessing Data from the Australian Data Archive.
4. Download the data
From the Study Page, you can also access the Nesstar data download system, to export the data files for the study to your own computer. In order to download data however, you need to have been approved for download access for the study you are interested in. This can be done by submitting a Request for Data Access from your personal User page. (Note: you need to be a registered user and logged in to make an access request). If you would like to request multiple studies at a time, simply add these to the Data Download request by selecting the additional studies you are interested in.
Once your download access has been approved, you will receive an email notification from ADA, and a link to the study will be added to your User Page.
To download data, follow the link on ADA to the study page, and click on "Analyse or Download this data in Nesstar" at the top of the study page. This will take you to the Nesstar system. From here you can then select the Download Data icon , choose the data format you would prefer, and then click on the "Download" button to download your data.
