Americans in Qatar are a large expatriate community who numbered around 3,800 in the year 1999. In recent years, this figure has more than doubled and various estimates now put the number of Americans in Qatar to be up to 15,000. Most Americans within the country tend to be based in the capital city of Doha and are largely attracted by the tax-free inducement of the gulf state.
