There are all kinds of differences between the United Kingdom and the United States. Some are governmental: the U.S. has a federal structure and a president, making its executive branch separate and equal with its legislative and judicial branches. The U.K. has a parliamentary system: members of the legislature are elected to serve within it, and the largest party forms a government, drawing its executive ministers from within the legislature. And, of course, there's the monarchy.

Other differences between the two nations are financial. For example, the top tax rates kick in at lower brackets in the U.K. than in the U.S., but citizens get a lot more for a very similar overall tax burden, including healthcare that is free at the point of need. 

Other differences are cultural. For example, the U.K. makes quite a ritual out of drinking tea, while Americans tend to prefer coffee. Brits drive on the left, while Americans drive on the right. Only a few Brits own guns and, by law, keep them in gun cabinets, while many more Americans own guns and specific laws vary state to state.

However, few of the differences are as obvious as those surrounding language. Each country has a number of accents and idioms within its borders, and a person's use of these will often tell not just which nation they herald from, but where specifically. Can we pinpoint you, at least down to the country? Let's find out!
