Requesting different types of data

Requests for aggregate data

Aggregate data is statistics that have been processed in a summary or table form, for example, incidence numbers and rates. It could be taken from our published reports. Do check these reports before submitting a request for aggregated data.

Requests for non-identifiable and key-coded data

Non-identifiable and key-coded data are individual, record-level data with no data that could identify the person which the record refers to. Key-coded data contain surrogate identifiers, whereas non-identifiable data doesn’t. Surrogate identifiers are useful to determine if there are multiple episodes for the same records.

For non-identifiable or key-coded data requests, you must analyse the data in the NRDO office, and will only be given the output as aggregate data. Data will not be released in record level format.

Requestors may request for data variables using the following lists. Please tick the checkboxes and provide justifications accordingly. All requests will be subjected to approval.
