American studies as an academic discipline is taught at some British universities and incorporated in several school subjects, such as history, politics, and literature. While the United States of America is the focus of most study, American Studies can also include the study of all the Americas, including South America and Canada. The methods of study are interdisciplinary, and students and researchers come from many fields, including anthropology, cultural studies, history, literature, film studies, gender studies and economics. Because of Britain's long association with the Americas, there is also a history of comment and analysis of the geography, culture and peoples of America, from Sir Walter Raleigh and Charles Dickens to Rudyard Kipling and Alistair Cooke.
