"In Canada and the United States, the term  football usually refers to a ball made of cow hide leather, which is required in professional and  collegiate football. Footballs used in  recreation, and in organised youth leagues, may be made of  rubber or plastic materials (the  high school football rulebooks still allow the inexpensive all-rubber footballs, though they are less common than leather)."
