Data Users

Thank you for considering using data from Fiji National Microdata Repository. This page describes how you may search, browse, understand and download a microdata set contained in the Repository.

The Fiji National Microdata Repository is a web-based cataloging system that serves as a portal for public health practitioners and researchers to browse, search, compare, apply for access, and download relevant data collected under various data collection initiatives. The data may come from various population based surveys conducted periodically by various technical programs in Ministry of Health as part of their program monitoring and evaluation as well as from routinely reported data from health facilities at all levels and from research projects.

The repository provides rich, fully searchable metadata, and controlled access to the microdata.


Searching the Microdata Catalog:


The users may search the catalog to find appropriate datasets by using relevant keyword given in either the study description or in one of the study's variables. The user enters their keywords in the search field, and based on the items selected in the checklist, the catalog returns a list of datasets containing the keywords entered.



Understanding the Metadata And Access Level to Different Datasets:

Once the user found the survey or variables in the catalog, the user can browse the rich metadata about each data set to understand it further before actually downloading it.


Understanding the access level to your microdata set:

Different data sets may have different access levels depending upon the level of sensitivities involved and other criteria. Overall, there are five different types of access levels:

Access Levels


Direct Access Data Files: these microdata sets are directly downloadable from the catalog without any restrictions. The user is not required to be logged into the site and no information is collected on the person downloading the data.


Public Use Data Files: requires the user to be logged in and registered on the site before they are able to download the data. The user is required to agree to a terms of use of the data and the application keeps records of who downloads the data. 


Licensed Data Files: requires that user to be logged in and registered on the site. Users are also required to fill in and submit a detailed application form listing their reasons for wanting access to the data. Once the user submits the application form, the system informs the system administrator that a request for data has been made. In order for the user to get access to the data the system administrator needs to review the application and approve it.


Data available in an Enclave: under this policy no data is available for direct download through the online repository. Users submit a written request to access the data at a secure facility physically located on the premises of the data producer or a facility nominated by the data producer.

Data available from external repository: the datasets are not directly stored in the Fiji National Microdata Repository, but the user can access the survey data from another repository.



Downloading and Exporting Datasets:

The microdata files are provided in a .Nesstar zipped format as well as in one of the data format (e.g. STATA or SPSS format). However, if the user wants the datafile in a different format other than provided, they should download the Nesstar file instead. Nesstar file regroups datasets and metadata of a survey in a single format file. The user thus needs to have an unzipping software as well as software that can open and read .Nesstar files.

A free reader application, the Nesstar Explorer allows users to view metadata and export data to common statistical formats. Once installed, users will be able to open the downloaded and unzipped files with the Nesstar Explorer.

Download Nesstar Explorer v3.62 for Windows system


When opening Nesstar Explorer, the user will immediately be prompted to select a Nesstar file to open. The application will start displaying a two-frame interface. The left frame provides a navigation tree. The right frame displays the content of the item selected in the navigation tree.

Data in the Nesstar format cannot be read by standard statistical software like STATA, SPSS or SAS. However, the Nesstar Explorer allows users to export data files into multiple types of formats so that analysis can be performed with statistical software the user is familiar with. To export a single data file:



1: Select the desired data file in the folder pane.

2: Select File > Export Dataset. This will open the Export Dataset window.

3: Choose the format in which to export the data by picking from the drop-down list under Save as Type.

4: Enter a name and location for the exported file and click Save.




Exporting the dataset to ASCII format requires that the dataset be properly resequenced before the .Nesstar file is saved.


It is also possible to export multiple data files in one operation:

     1. Select File > Export All Datasets from the main menu. This will open the Export Datasets window.
     2. Select the datasets you wish to export by clicking the check boxes in the Datasets frame.
     3. Choose the format in which to export the data.
     4. Choose the location in which you want to save the data files, select the desired location.
         The option is also given to create a sub-folder to the export folder.
     5. Select OK to perform the data export.
