Usonian

Of or related to the United States of America; term coined by Frank Lloyd Wright to refer to his new ideal for architecture. This word is preferable to "American" since there are dozens of countries in North and South America. In some Latin American countries, such as Brazil, the use of "American" to refer to US nationals is considered offensive and officially discouraged.

While Canadians and Usonians share a common heritage and close proximity, there are some subtle cultural differences.
