This report is one of the 58 numbered parts of Population Census Volume I. Each of these parts contains four chapters, A, B, C, and D, originally published in the PC(1)-A, B, C, and D series of individual reports (except parts 54-58 which contain only chapters A and B). As indicated in the listing below there is one numbered part for the United States, each State, the District of Columbia, Puerto Rico, Guam, Virgin Islands, American Samoa, Canal Zone, and Trust Territory of the Pacific Islands. The starting page numbers for chapters A, B, C, and D are given below; the first page of each chapter presents a list of contents. The present publication includes changes for typographical errors found in some maps and tables after issuance of the series of individual reports, but the tables have not been revised to reflect the corrections listed on pages 37-40 and 359 for this report.
