These sources have been chosen because each of them includes not only current but also historical statistics.
Many of them include both U.S. and international statistics unless otherwise noted.
Aside from citing articles and books, have you ever wondered how to cite a company annual report or an industry report? The reality is, there is no "official" style for citing business sources. However, it is common practice to use adaptations of one of the following citation styles: the American Psychological Association (APA) Style or the Chicago Style. Whichever style you choose, use it consistently for the entire project/paper.
