The social and population statistics architecture provides a high-level view of the primary data sources and the ways in which they are combined to meet information needs in the future. Information needs will change over time, and we can expect continued demand for more detailed, complex, and comprehensive data. These demands must be met within constraints imposed by funding, by respondent burden, and by privacy concerns.
This architecture is a continuation and development of the existing model of a Census of Population and Dwellings and household sample surveys supported by administrative data. There is no paradigm shift; rather it is an evolving system.
Improvements are two-fold: be as efficient and effective as possible in conducting the census and household survey programme; and combine administrative and survey sources using statistical techniques that make up for the weaknesses of each source through the strengths of the other.
