What are the indicators of GDP as a good measure of standard of living?

While GDP can be a useful indicator of a country's economic health and, by extension, its standard of living, it has several limitations and nuances. Here are the key indicators and considerations:

GDP Per Capita

GDP per capita, calculated by dividing the total GDP by the population, is often used as a proxy for the standard of living. This measure provides an average income figure per person, which can give insights into the economic welfare of a nation134.

Real GDP and Purchasing Power Parity

To adjust for inflation and regional price disparities, economists use real GDP (which accounts for inflation) and GDP per capita adjusted for purchasing power parity (PPP). These adjustments help in getting a more accurate picture of the true income and purchasing power of the population14.

Correlation with Economic Development

Higher GDP per capita is generally associated with better living conditions, such as improved life expectancy, reduced poverty, and increased investment in technology and public services. Economic development, as measured by GDP, plays a crucial role in enhancing life satisfaction and public service satisfaction134.

Human Development Index (HDI)

The HDI, developed by the United Nations Development Programme, includes measurements of life expectancy, education, and per capita income (often using GNI or GDP per capita as a substitute). This index provides a more comprehensive view of well-being by incorporating non-economic factors1.

Limitations

Despite its usefulness, GDP has several limitations as a measure of standard of living:

  • Non-market activities: GDP does not account for non-market activities like volunteering, caregiving, and household work, which are important to people's well-being245.
  • Income inequality: GDP does not capture distributional issues such as income inequality and poverty, which significantly impact well-being245.
  • Environmental and health impacts: GDP ignores the costs of environmental degradation and negative externalities on human health25.
  • Subjective well-being: GDP does not capture subjective measures of well-being like happiness, life satisfaction, or mental health25.

Multidimensional Measures

For a more comprehensive understanding, it is recommended to use GDP per capita in conjunction with other multidimensional measures of well-being, such as the HDI or other indices that include social indicators like education, health, and environmental quality134.

In summary, while GDP per capita is a significant indicator of the standard of living, it should be used with the understanding of its limitations and ideally complemented with other measures to get a fuller picture of well-being.
