IMPORTANT FACTS - GDP (Gross Domestic Product) is the measure of the total size of a country’s economy.
This is the economic value of all the goods and services produced and provided by a country during the course of one year; this is divided by the total number of people in that country to calculate GDP per capita. The final amount is worked out in US dollars and gives an idea of the strength of the economy. The higher the GDP the more developed a country is likely to be. In 2017, the UK had a GDP of $ 38,847 USD per person per year which ranks the UK 22nd internationally (IMF figures - Source). Ghana, by comparison, has a GDP of around $ 1,607 per person.
In 2017, UK GDP was estimated at US$2.56 trillion (approx £1.46 trillion) - the 6th largest economy in the world (IMF figures - Source)

Purchasing Power Parity (PPP)
This adjusts GDP for the relative cost of goods and services in different countries. Find a full explanation here. Once this has been taken into account:
- The UK's "PPP" GDP in 2017 was US$2.88 trillion - 9th largest economy (IMF figures - Source)
- Per capita this is US$43,620 – 26th internationally (IMF figures - Source)
Big Mac Index
This is one way to measure Purchasing Power Parity - by comparing the relative prices of Big Macs in different countries. The index was created by The Economist and has been extended to give the figure for how long someone in a country needs to work in order to earn enough for a Big Mac. It isn't perfect as in some countries Big Macs are cheap food and in others considered a luxury.
See here for the latest Big Mac Index.
Other similar measures exist such as the Tall Latte Index of the cost of Starbucks coffee.
Human Development Index (HDI)
It is important to note that GDP per capita and well-being are not always linked! Whilst GDP per capita is useful, it masks inequality, particularly in countries with large populations. Being aware of indices of inequality such as the 'Gini Coefficient' could therefore be useful as a point of discussion
HDI offers an alternative to GDP per capita. It is a comparative measure of life expectancy, literacy, education and standards of living for countries worldwide, forming a standard means for measuring wellbeing (especially child welfare). It is used to distinguish whether a country is developed, developing or under-developed, and also to measure the impact of economic policies on quality of life. There are also HDIs for states, cities, villages, etc. collated by local organisations or companies.
The UK ranks 16th in the world in this index (according to 2015 data) and is considered to have "Very High Human Development" (Source)
