Total annual rice production: Highest producers in dark green are China and India. Some of the higher-producing countries in green and light green are Russia, Brazil, U S A, and some of the low-producing countries (very light green) are Mexico and Australia.

The map shows striking regional differences in the percentage of change in the population of counties in the United States between 2000 and 2010. In the Northeast and Midwest, most counties either had small gains of between 0 and 4.9 percent or lost between 0 and –5 percent. In a few counties in upstate New York, western Pennsylvania, eastern Ohio, and parts of northern Michigan, Wisconsin, and Minnesota, losses exceeded 5 percent. Western Ohio, northern Indiana, much of Illinois, and eastern Iowa experienced modest declines of between 0 and –5 percent. At the same time, population increased by 5 to 14.9 percent in southern Minnesota, Wisconsin, Missouri, and parts of Indiana and Ohio. In the South, many areas showed strong growth—from 5 to 14.9 percent and higher—including Maryland, Virginia, Delaware, North Carolina, Georgia, Florida, and Tennessee. Counties lost population (between 0 and –5 percent, with significant numbers of counties less than –5 percent) in West Virginia, eastern Kentucky, Alabama, Mississippi, Arkansas, and northern Louisiana. From the Northern Plains to Texas, a vast area of rural counties lost significant numbers of residents—declines of more than –5 percent in many counties. This population loss is most evident in eastern Montana, North and South Dakota, Nebraska, western Iowa, Kansas, southeastern Wyoming, Colorado, and West Texas. In contrast, counties in the Rocky Mountains, Great Basin, and Southwest often experienced strong growth—from 5 to 14.9 percent and higher—as exemplified by western Montana, southern Idaho, most of Wyoming and Colorado, parts of New Mexico, much of Nevada, and virtually all of Utah and Arizona. The Pacific coast states of Washington, Oregon, and California also grew, except for eastern Oregon, which saw declines from 0 to –5 percent and less. Hawaii’s population grew by more than 14.9 percent. In Alaska, the counties around Anchorage and Fairbanks also made strong gains, whereas other counties declined or grew slightly.

A map illustrates the distribution of calcium carbonate in modern surface sediments globally, with highest concentration found in the Caribbean, Mediterranean, and South Pacific and lowest concentration dominating the North Pacific, and Southern Ocean.

Percentage of ocean surface comprised of calcium carbonate.

Distribution of Calcium Carbonate in Modern Surface Sediments

The distribution is represented as a percentage by weight. Areas with the least calcium carbonate, ranging from 0 percent to 20 percent, are marked in very light blue and are prevalent in large parts of the Pacific Ocean, particularly around Samoa, the South Pacific, and parts of the Indian Ocean. Light blue regions, representing 20 percent to 40 percent calcium carbonate, cover parts of the North Atlantic Ocean, including areas around Cuba, the western coast of Africa near Senegal and Mauritania, and the southern Indian Ocean near Madagascar. Medium blue areas, indicating 40 percent to 60 percent calcium carbonate, include regions in the North Atlantic Ocean, off the coast of the United Kingdom and France, the Mediterranean Sea, parts of the Arabian Sea, and the South Pacific Ocean. Blue-green regions, with 60 to 80 percent calcium carbonate, are seen in the central Atlantic Ocean, areas around the Caribbean including Cuba and Guatemala, the western coast of Africa near Gabon and Angola, and the Indian Ocean. The highest concentration of calcium carbonate, 80 percent to 100 percent, marked in dark green, is found in regions of the North Atlantic Ocean, around the Bahamas and north of Cuba, parts of the South Atlantic Ocean near the eastern coast of South America, the central Pacific Ocean, and the northern Indian Ocean near Sri Lanka.
