The World Giving Index (WGI) is an annual report published by the Charities Aid Foundation, using data gathered by Gallup, and ranks over 130 countries in the world according to how charitable they are. The aim of the World Giving Index is to provide insight into the scope and nature of giving around the world. The first edition was released in September 2010. The most recent edition was published in November 2015, with Myanmar, the USA and New Zealand ranking as the top three. Canada, Australia, the United Kingdom, the Netherlands, Sri Lanka, Ireland and Malaysia complete the top ten. == Methodology == This report is primarily based upon data from the Gallup World Poll, which is an ongoing research project carried out in more than 140 countries that together represent around 95% of the world’s adult population (around 5 billion people). In most countries surveyed, 1,000 questionnaires are completed by a representative sample of individuals living across the country. The coverage area is the entire country including rural areas. The sampling frame represents the entire civilian, non-institutionalised, aged 15 and older population of the entire country. In some large countries such as China and Russia samples of at least 2,000 are collected, while in a small number of countries, the poll covers 500 to 1,000 people but still features a representative sample. The survey is not conducted in a limited number of instances including where the safety of interviewing staff is threatened, scarcely populated islands in some countries, and areas that interviewers can reach only by foot, animal or small boat. 〔(Gallup World Poll Methodology ), Retrieved 10 November 2015.〕 In all, over 150,000 people were interviewed by Gallup in 2014 and samples are probability-based. Surveys are carried out by telephone or face-to-face depending on the country’s telephone coverage.〔 There is of course a margin of error (the amount of random sampling error) in the results for each country, which is calculated by Gallup around a proportion at the 95% confidence level (the level of confidence that the results are a true reflection of the whole population). The maximum margin of error is calculated assuming a reported percentage of 50% and takes into account the design effect. Gallup asked people which of the following three charitable acts they had undertaken in the past month:〔 * helped a stranger, or someone they didn’t know who needed help? * donated money to a charity? * volunteered your time to an organisation? 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「World Giving Index」の詳細全文を読む スポンサード リンク
