The BBC questioned people in 23 different countries on what they though were the big problems facing the world. Over 25,000 people were interviewed for the survey. Respondents were given a list of problems and were asked to give their opinion of the degree of it's severity, ranging from 'very serious' to "not serious'.

In this year's poll, poverty was rated as the most serious global issue in 10 of the countries polled, including in the UK, US, Kenya, Australia, Brazil and Chile. However, in Russia, Turkey, Mexico, Indonesia and Nigeria more felt that the rising cost of food and energy was very serious.
The poll, which was conducted before the Copenhagen summit took place, also found that the Japanese were the only nation to regard climate change as the most serious global issue – although the Chinese and Costa Ricans identified environmental issues more generally or pollution as the most serious.
The Chines ranked climate change as the second most serious issue, whereas Americans ranked it ninth.
If poverty is seen as the world's most serious problem, it is not the most top-of-mind. When respondents were asked to name spontaneously 'the most important issue facing the world today', economic problems were most commonly cited, with one in four mentioning them (26%). Terrorism and war followed with 10 per cent.
And while poverty was some distance ahead of other global issues in terms of how serious it was seen to be, it was only one of a number of issues that people had discussed with friends and family recently. The greatest number - 30 per cent - said they had talked about rising food and energy costs with their friends and family recently, with extreme poverty and the spread of human diseases the second most discussed issues (29 per cent) and the state of the global economy third (28 per cent).
