A major difference is that the UNECE’s framework does not have support any particular policy agenda, and as such does not have any policy focus, and the indicators are selected and presented as a toolbox for National Statistics Offices. By contrast, the OECD's Framework is meant to be more operational and policy-based and builds on the UNECE toolbox. Therefore the two approaches can be considered as mutually supportive. Furthermore, they should also fulfil standard statistical requirements, e.g. come from official or other well-established sources, be defined in a comparable way, have data collected regularly and be timely.
