Measures of life value: These refer to the ranges of the fields of life value which are maintained, gained or lost at the margins in reference to a prior or compared state (e.g., at the collective level, literacy rate growth, caloric and protein intake compared to health requirements, and housing ratios per capita to ratios of able-bodied citizens to available meaningful work of value to others).
Although life-value measures are not commensurable across fields and domains of life without reduction to fungible monetary units abstracting away all life contents, direct and accurate measure of more or less ranges of life is applicable to phenomena in any life-field or domain.
Life-value measure is applicable to phenomena in any life-field or domain by identification of more/less range of life capacity through time.
