Adrian White, an analytic social psychologist at the University’s School of Psychology, analysed data published by UNESCO, the CIA, the New Economics Foundation, the WHO, the Veenhoven Database, the Latinbarometer, the Afrobarometer, and the UNHDR, to create a global projection of subjective well-being: the first world map of happiness.

Participants in the various studies were asked questions related to happiness and satisfaction with life. The analysis is based on the findings of over 100 different studies around the world, which questioned 80,000 people worldwide. For this study data has also been analysed in relation to health, wealth and access to education.

Whilst collecting data on subjective well-being is not an exact science, the University' research team say that the measures used are very reliable in predicting health and welfare outcomes. They argue that whilst these measures are not perfect they are the best we have so far, and these are the measures that politicians are talking of using to measure the relative performance of each country.

The researchers have argued that regular testing as a collaboration between academics in different countries would enable us to track changes in happiness, and what events may cause that. For example what effect would a war, or famine, or national success have on a country's members' happiness.

Adrian White said:

“There is increasing political interest in using measures of happiness as a national indicator in conjunction with measures of wealth. A recent BBC survey found that 81% of the population think the Government should focus on making us happier rather than wealthier.

"Further analysis showed that a nation's level of happiness was most closely associated with health levels (correlation of .62), followed by wealth (.52), and then provision of education (.51).

White continued:

“There is a belief that capitalism leads to unhappy people. However, when people are asked if they are happy with their lives, people in countries with good healthcare, a higher GDP per capita, and access to education were much more likely to report being happy.

“We were surprised to see countries in Asia scoring so low, with China 82nd, Japan 90th and India 125th. These are countries that are thought as having a strong sense of collective identity which other researchers have associated with well-being.

"It is also notable that many of the largest countries in terms of population do quite badly. With China 82nd, India 125th and Russia 167th it is interesting to note that larger populations are not associated with happy countries."

White added:

“The frustrations of modern life, and the anxieties of the age, seem to be much less significant compared to the health, financial and educational needs in other parts of the World. The current concern with happiness levels in the UK may well be a case of the 'worried well'."
