A culture region is a section of land that has common cultural elements. These elements can include religion, language, cuisine or architecture, among many others. Culture regions are found on every continent except Antarctica.
The lands within culture regions can vary dramatically in size from a few square miles to millions. The Islamic culture region across North Africa and Southeast Asia is among the largest and covers millions of square miles, while Spanish Harlem in Manhattan encompasses only 2. Cultural regions have changed, expanded and diminished throughout history and will continue to do so as the world experiences more ethnic change.
