“MF” is the attribution of global material extraction to domestic final demand, hence is given in absolute tons, in t per person, or in t per GDP

3 Pros:
•    Referencing per person, per GDP or per country links to a target of economic activity
•    Thus, economic performance is measurable
•    Efficacy of resource usage is very telling

3 Cons:
•    Interpretation of MF/person needs care
•    Interpreting MF/GDP implicitly promotes the target of material welfare as life’s target
•    Interpreting MF/country should respect the local geological & meteorological framing
