Difficulties in measuring living standards

The most common method for measuring living standards is using GDP per capita. This is national income divided by population and gives a rough guide to average incomes. High real GDP per capita indicates citizens are able to purchase more goods and services.

This shows variation in GDP per capita of $100,000 to $118 in the poorest countries.

However, there are several difficulties in using GDP to measure living standards.

Difficulties measuring living standards

1. Purchasing Power Parity. When comparing living standards between different countries, it is important to take into account different purchasing power parity’s (PPP) – GDP per capita in $ terms does not necessarily reflect the local purchasing power of a country. For example, in Namibia incomes may be quite low – say $1,000 per capita. However, living costs are likely to be much lower in Namibia than say the US. With $1,000 you can buy a lot more in Namibia than in the UK or US. Therefore, it is important to take these factors into consideration when comparing living standards between countries


If we use GDP per capita in purchasing power parity (PPP) then income differentials are smaller.

2. Economic activity not measured. Some countries may have large ‘black market’ or economic activity that isn’t measured by official statistics. For example, in a country like Namibia, there is likely to be a significant degree of subsistence farming. This makes zero contribution to GDP statistics because nothing is officially produced, but people may have decent living standards.

3. Externalities of growth. Higher GDP suggests higher living standards, but higher economic growth may be at the cost of increased pollution and congestion. This leads to a decline in living standards (poor health from pollution, time wasted from congestion) therefore GDP overestimates living standards. This has been an issue for countries like China – whose breakneck economic growth has been at the expense of pollution.

4. Hours worked Two countries may have similar GDP, but if one country has an average hourly week of 60 hours worked, this suggests lower living standards than a country which has an average of only 40 hours per week.

5. Poverty. Living standards need to take into account how income and expenditure are distributed through society. A country may have high GDP per capita but still have significant poverty. Other measures of living standards, such as Human Development Index (HDI), try to include these factors.

6. Intangibles. Living standards are not just about consumption of goods and services. Arguably a key factor in living standards is issues such as a degree of individual liberty/democracy and freedom. This becomes difficult to quantify from an economic perspective.

7. Literacy.  Access to education is considered an important aspect of living standards. Without education, people will struggle to obtain their potential and their human capital will be lower. Education can also improve living standards in non-monetary ways – enjoying a greater degree of culture

8. What do we mean by living standards? Some may think of living standards through financial measures (e.g. income e.t.c). Others may place less emphasis on this and focus on issues such as the environment, ‘general well-being’ and levels of happiness.

Other measures of living standards

1. Human development index

A composite index including real GDP at PPP, education levels and healthcare standards


Index of Human Poverty HPI

Similar to HDI, but a greater weighting to equality of distribution and levels of absolute poverty.
