Real GDP per capita serves as a primary correlational metric for estimating average standard of living within macroeconomic theory, specifically linking material aggregate production to non-material outcomes such as life expectancy and human development. While formal correlation coefficients establish positive relationships between national income levels and societal well-being indices like the Human Development Index (HDI), this theoretical framework operates under the boundary condition that it fails to account for intra-national income distribution inequality without supplementary data on poverty stratification. Despite these distributional limitations, growth in real GDP per capita theoretically implies proportional increases in living standards across diverse population segments over time.
