1950 POPULATION OF THE STATES Average Increase for United States: 14%% loss since 1940. 834 Drawn by Harry S. Oliver Forty-four of 48 States Gained Population in the Fruitful Forties Biggest gainers are the 19 dark gray States and the District of Columbia. They increased by a higher percentage than the Nation as a whole, with California leading (see below). Light gray States gained less than the national average. States shown in white lost population. leap up the population ladder was foreshad owed in a NATIONAL GEOGRAPHIC article under the subhead, "Baton Rouge Still Can't Believe It!" * Huge plants turn out synthetic rubber, avia tion gasoline, and a host of other petroleum products. They boosted the Baton Rouge population by 257.03 percent in ten years. Growing from 34,719 to 123,957, the Loui siana capital shot up from 288th to 84th place. Effects of war and defense preparations are dramatically shown by the mushroom growth of little Windham, Ohio, near Ravenna. It grew by 1149.1 percent, from 316 inhabitants to 3,947, because of the location of the big Ravenna Arsenal near by. Even this growth is overshadowed by the new "atomic cities"-Oak Ridge, Tennessee; Richland, Washington; and Los Alamos, New Mexico. They boomed from virtually noth ing to 30,236, 21,793, and 9,927 respectively. Most of the 2,187 place names added since the 1940 U. S. map appear in the western States, again the region of greatest percentage growth. So do most of the giant dams built during this dynamic decade when hydroelectric capacity increased by 57 percent. Among them are eight of the world's ten highest, nota bly Grand Coulee in Washington, Shasta in California, and Hungry Horse, the newest, in Montana, for power, irrigation, and flood con trol. The program is still in full swing.f Between 1940 and 1950, California grew by 53.3 percent, adding more than 3/2 mil lion. In State rank she jumped from fifth to second, passing Ohio, Illinois, and Pennsyl vania. Second and third honors for rate of growth went to two other sunny States Arizona, with a gain of 50.1 percent, and Flor ida, with 46.1 percent. Population shifts will be reflected in Con gress, for census figures form the basis for representation in the House of Representa tives. If the membership of the House is kept at 435, nine States will lose Congressmen to seven other States. Those that will gain are California, Florida, Maryland, Michigan, Texas, Virginia, and Washington. Those that will lose: Arkansas, Illinois, Kentucky, Mis sissippi, Missouri, New York, Oklahoma, Pennsylvania, and Tennessee. Largest U. S. cities (over 500,000) are: New York, 7,835,099; Chicago, 3,606,436; Philadelphia, 2,064,794; Los Angeles, 1,957, 692; Detroit, 1,838,517; Baltimore, 940,205; Cleveland, 905,636; St. Louis, 852,623; Washington, D. C., 802,178; Boston, 790,863; San Francisco, 760,753; Pittsburgh, 673,763; Milwaukee, 632,651; Houston, 594,321; Buf falo, 577,393; New Orleans, 567,257; Minne apolis, 517,277; and Cincinnati, 500,510. * See "Louisiana Trades with the World," by Fred erick Simpich, in the December, 1947, NATIONAL GEO GRAPHIC MAGAZINE, page 724.
