National Geographic : 1940 Dec
New United States Map Shows Census Changes SWIFT-CHANGING America, altered mightily in a decade by engineers and builders, rather than scarred by bomb and blitzkrieg, along with epochal population movements, is delineated in the new 10-color map supplement of the United States, 41 by 26/2 inches, which accompanies this issue of the NATIONAL GEOGRAPHIC MAGAZINE.* Hereon are shown striking results of the 1940 census, most comprehensive enumeration in all history, and also historic alterations on the face of a vast nation-new dams and ex press highways, newly created national parks and monuments, expanding cities and dust bowl migrations, and defense bases and sites of camps where millions of the country's first peace-time conscripted forces will train. Increases and decreases of State populations are recorded in another inset, and the altered order of our 30 biggest cities is given in a table comparing their 1930 size with that of 1940. Besides the 48 States of the Union, "from sea to shining sea," the new map shows all of the Maritime Provinces of Canada and most of its industrially developed section, Mexico as far south as the Tropic of Cancer, and vir tually all of the Bahama Islands, site of one of the eight new air and naval bases acquired by lease from Great Britain. Miami Beach Has Biggest Gain In the light of the latest census, scores of towns and cities emerge for the first time on a national map, most of them in the western States. Thirty others-notably Charlotte, North Carolina, and Sacramento, California, which have passed the 100,000 mark-move into heavier type with an increased population, while a few drop into a lower classification. On the map appear 8,838 place names, 288 of which have been added since The Society last mapped the Nation seven years ago. Biggest percentage gain recorded for any city was made by Miami Beach, Florida, which grew 321 per cent in the last ten years-from 6,494 to 27,340. But even that is small com pared to its 908.4 per cent growth in the 1920's. In 1910 it did not exist. Among the larger cities, those of 100,000 or more, Miami, Florida, made the greatest in crease, with 54.4 per cent. San Diego, Cali fornia, was second with 36.5 per cent, and Washington, D. C., third, with 36.2 per cent. Among cities of a million or more, Los An geles, with its area of 365.7 square miles, grew fastest in population. It gained 20.9 per cent. Of the Nation's top thirty cities-those above the 300,000 level-Baltimore has moved ahead of St. Louis. Washington, with its mul- tiplying government activities, has shot up from fourteenth to eleventh place, entering the 500,000-to-a -million class. Moreover, suburban counties surrounding the Nation's Capital were among the most rapidly growing in the country. Arlington County, Virginia, gained 112.3 per cent and Montgomery County, Maryland, 65.5 per cent. Army Training Camps Shown The special National Defense inset shows the nine Corps Areas of the United States Army, with the various corps area and division headquarters, principal air stations, posts and recruit reception centers. National Guard divisional areas are out lined to indicate the States from which the divisions are drawn. Each division is num bered in red and its training camp bears the corresponding number. Thus friends of a National Guardsman from Ohio can see at a glance that his division, the 37th, trains at Camp Shelby, Mississippi. A New Yorker, belonging to the 27th Division of the National Guard, would train at Fort McClellan, Anniston, Alabama. The 26th, or Yankee Division, trains in Massachusetts at Camp Edwards, named for its World War commander. Most of the other northern units drill in the South. On the same inset appear naval and subma rine bases, torpedo stations, navy yards, ma rine barracks, and naval air stations, including the big southeastern air base recently com pleted at Jacksonville, Florida, more than six months ahead of schedule. Also of major im portance in the program of the expanding Navy is the United States Fleet Training Base on San Clemente Island, California, between San Diego and Los Angeles. Population shifts revealed by Uncle Sam's immense nose-counting chore, the 1940 census, are indicated in another eloquent inset. Shown in white are the six States which de creased in population during the decade North and South Dakota, Nebraska, Kansas, Oklahoma, and Vermont. Never before in United States history have more than three States shown a loss. The explanation in the case of the first five is drought, for these Great Plains States reflect the exodus from the Dust Bowl, reaching from Texas to Canada. * Additional copies of the map The United States may be obtained by writing to the National Geo graphic Society, Washington, D.
