The Act is significant for South African public administration and statistics governance because it modernises the Statistics Act 6 of 1999, broadens the institutional scope of the National Statistics System, strengthens the co-ordinating and supervisory role of the Statistician-General, introduces mechanisms for quality assurance and designation of official statistics, requires organs of state to institutionalise statistical capacity, and creates a clearer framework for data-sharing, training, ethics, regulation, and statistical planning. It also expressly provides for the Act's primacy over conflicting legislation on matters within its scope, subject to the Constitution and express amendment.
