The United States is relatively young by world standards, being less than 250 years old. America was the first of the European colonies to separate successfully from its motherland, and it was the first nation to be established on the premise that sovereignty rests with its citizens and not with the government. In the 20th century, the United States emerged as a world power. The nation’s wealth is partly a reflection of its rich natural resources and its enormous agricultural output, but it owes more to the country’s highly developed industry. Despite its relative economic self-sufficiency in many areas, the United States is the most important single factor in world trade by virtue of the sheer size of its economy.

The United States’ physical environment ranges from the Arctic to the subtropical, from the moist rain forest to the arid desert, from the rugged mountain peak to the flat prairie. Although the total population of the United States is large by world standards, its overall population density is relatively low. The country embraces some of the world’s largest urban concentrations as well as some of the most extensive areas that are almost devoid of habitation.

Tourism in the United States is a large industry that serves millions of international and domestic tourists yearly. Tourists visit the US to see natural wonders, cities, historic landmarks, and entertainment venues. Americans seek similar attractions, as well as recreation and vacation areas. In the US, tourism is either the first, second, or third largest employer in 29 states. As of 2016, Orlando is the most visited destination in the United States. Tourists spend more money in the United States than any other country, followed by France. One hundred million tourists visited Florida in 2015, a record for the nation.

England, the predominant unit of the United Kingdom (England, Scotland, Wales, Northern Ireland), occupies more than half the island of Great Britain. With over 65 million inhabitants, England is by far the most populous country of the United Kingdom. England's long and storied history and pervasive culture spread worldwide through the English language and made England a popular tourist destination. The United Kingdom is the world's eighth biggest tourist destination, with over 36 million visitors in 2015.

The country's principal tourist destinations are in London, with the Tower of London being the single most visited attraction in the country. The London Eye, Buckingham Palace, Big Ben, the National Portrait Gallery, and Westminster Abbey are only a few of London’s hugely popular attractions.

Although Wales closely shares its political and social history with the rest of Great Britain, and the vast majority of the population speaks English, the country has retained a distinct cultural identity and is officially bilingual. Over 560,000 Welsh language speakers live in Wales, and the language is spoken by a majority of the population in parts of the north and west. Cardiff is the capital and biggest city in Wales and the tenth biggest city in the UK. 

Although Wales has its own traditional food, it has absorbed much of the cuisine of England and Welsh diets now owe more to the countries of India, China and the United States. Both beef and dairy cattle are raised widely, but Wales is more well known for its sheep farming and thus lamb is the meat traditionally associated with Welsh cooking. Chicken tikka masala is the country's favourite dish while hamburgers and Chinese food outsell fish and chips as a takeaway.
