- Purchasing Power Parity – a technique used to determine the relative value of different currencies by comparing countries.
- Real and nominal GDP:

- Real – shows the figure adjusted for price changes (e.g. inflation)
- Total and per capita GDP:

Comparing economic growth:
By using purchasing power parities, different currencies can be compared across various countries. The technique involves by comparing the value of a set basket of goods in different currencies using a base currency (e.g. US dollar) and an exchange rate. An example is the Big Mac Index which compares the price of a Big Mac in different countries by converting all currencies to the US dollar using exchange rates.
Limitations of GDP in comparing living standards between countries over time:
In the UK, the Office for National Statistics measures the national wellbeing of the population in order to assess the quality of life within the economy. An increase in real incomes is often linked to an increase in subjective happiness.

Limitations of GDP in comparing living standards between countries over time:
- GDP doesn’t account for the improving quality of goods over time (especially technological goods).
- The GDP figure doesn’t include unpaid or unofficial work such as washing your own car or the childcare of your own child. The value of the goods and services consumed by the producers is also excluded.
- The increase in real GDP may be shared unequally amongst the economy’s population so the GDP per capita figure may mask huge inequalities within the economy.
- An increase in GDP may lead to other problems: increased pollution, increased number of working hours, increased stress levels, etc. These can all lead to a worse standard of living.
In the UK, the Office for National Statistics measures the national wellbeing of the population in order to assess the quality of life within the economy. An increase in real incomes is often linked to an increase in subjective happiness.
Limitations of happiness measurements:
- Very difficult to measure
- Happiness can change quickly
- Happiness is often subjective
