National Geographic : 1968 Feb
New Map Charts FOR THE EIGHTH TIME in 45 years, the National Geographic Society this month presents a new wall map of The United States to its members as a supple ment to their magazine.* Since the Society issued its first such map in April, 1923, the country has grown by more than the present total population of France, Spain, and Switzerland combined. That first map showed a land of 48 states, 3,022,387 square miles, and 110,850,000 peo ple. Now the Nation is home to more than 200,000,000 Americans, and the admission of two states in the past ten years has added 592,824 square miles. The Nation's spiraling population-now adding one person every 141/2 seconds-passed the 200-million mark last November 20 (below). The new map, 421/2 by 291/2 inches, forms an impressive full-length portrait. With insets, it spans the 5,850 miles from Elliott Key, Florida, to Hawaii's Kure Island, west of Midway-greatest distance between any two points in the United States. Men and machines constantly change the face of the land. Including 6,000 miles under construction, the new high-speed Interstate Highway System, shown by yellow-filled dou ble red lines, extends for 32,500 miles of an eventual 41,000 miles (see article beginning on page 194). Beltways now circle several large cities, speeding traffic around instead of through these ever more congested urban centers. Across the middle of Lake Pontchartrain in Louisiana a single red line traces the world's longest bridge-24 miles from shore to shore. The longest bridge-tunnel combination Population grows: Census Clock in Washington, D. C., records a historic change at 11:03 a.m. on November 20, 1967. President Johnson marks the occasion with Census Bureau Director A. Ross Eckler, right, and Secretary of Commerce Alex ander B. Trowbridge, left. Dials light with each birth, death, immigrant, and emigrant. Living space shrinks: Homes, apartments, and shopping centers carpet a bluff above the Pacific in Daly City, California, within commuting distance of San Francisco. Two-thirds of the U.S . populace 220 live in burgeoning metropolitan areas.
