AVAILABILITY OF STATISTICAL INFORMATION
The administrative data source may not represent all of the population required by the receiving agency. Alternative methods and/or data sources may need to be used in conjunction with the administrative data in order to obtain the information required. It is also important to know at what level the data are being collected. For example if data are collected based on a post code this limits how the data can be grouped to represent the populations in different geographical areas that are not aligned with post code boundaries.
It is also important to be aware that the scope defined by the administrative data source may not be the same as the scope that is actually achieved by that data source due to issues with implementation and access to reporting units. Data custodians may not have a vested interest in following up where data are not recorded for some of the population because their focus is not on the use of the data for statistical purposes.
