Spotlight Dead Zones in the Chesapeake Bay
According to the Chesapeake Bay Foundation, the Chesapeake Bay ecosystem and many of it rivers and streams are losing their natural resiliency due to pollution, sprawling growth, and loss of habitat. In recent years the Bay's ecosystems have become increasingly unbalanced and are losing their ability to recover from continued pollution. This graph shows the volume (in million cubic meters) of dead zones in the Chesapeake Bay since 1950. Despite the relatively static levels of pollutant loads, evidence suggests the dead zone—the areas of the bay where levels of oxygen are too low to support most aquatic life—has increased over time.

Adopting New Farming Practices in India
How farmers get access to new and existing technologies is critical to increasing labor productivity. This graph shows the percentage of farmers adopting modern farming practices in Andha Pradesh, India by source of information. Word of mouth appears highly reliable, with 91.5 percent of farmers adopting new practices after approaching another farmer as a source of information. Extension workers and input dealers, public agencies meant to deliver knowledge to farmers, also prove to be effective. Extension workers as a source of information have only been accessed by 8.4 percent of farmers countrywide. Radio, newspaper, and television media also lead to about a fifty percent adoption rate.

Justifiable Homicides
A justifiable homicide is defined as the killing of a felon by a law enforcement officer in the line of duty or the killing of a felon during the commission of a felony by a private citizen. This graph shows the number of justifiable homicides committed by police officers and private citizens between 1976 and 2005. The number of justifiable homicides committed by the police tends to exceed the number committed by citizens. In the last 10 years the number of justifiable homicides has declined 13 percent.
Study Buddies: Use of Prescription Stimulants Among College Students
Final exams at many U.S. colleges are just around the corner -- how many students are getting a little extra help studying? A report in Addiction Journal found that 6.9 percent of students had ever used non-medical prescription stimulants (Ritalin, Dexedrine or Adderall). 4.1 percent of students had used stimulants in the past year, and 2.1 percent had used them in the past month. This graph shows the percent of students who had used stimulants in the past year by the U.S. geographical region their college is located in. Rates were higher at colleges located in the north-eastern region of the U.S. and at colleges with more competitive admissions standards. The report also found that stimulant use was higher among college students who were male, white, members of the greek system and earned lower grade point averages. Users were more likely to report use of other recreational drugs.
YouTube Generation
According to a recent report from PEW, young adults are almost twice as likely to point to YouTube as a source for online video; 49 percent of viewers ages 18-29 say they watch YouTube, compared to 27 percent of viewers of all ages. This graph shows the percentage of young adults compared to viewers of all ages by different venues of watching video online. MySpace receives a smaller young adult audience than YouTube with 15 percent of young adult viewers and 6 percent overall. Cable and network TV sites are less popular among young adults, as well as news websites which garner 12 percent of viewers of all ages compared to 6 percent of young adults.
GDP per capita of OECD Countries
The Gross Domestic product (GDP) per capita is one way to measure the size of a country's economy. This graph ranks the different OECD countries according to their GDP per capita in 2006. OECD ranked Luxembourg, Norway, the United States, and Ireland as having the highest GDPs per capita. Due to the complex nature of this aggregate, slight differences between countries should not be taken into account. Check out OECD's Factblog on the topic. Data uploaded by official source, OECD.
Water Efficiency and Energy Production
How much water is used by various energy production and power generation technologies? This graph shows the low range of water use efficiency of various energy production technologies. In terms of power generation, nuclear energy is the least water efficient while hydroelectric power is the most water use efficient system. Data uploaded by hayden.
Recycling Electronic Waste
E-waste, or electronic waste, is the fastest growing form of toxic waste in the world. It is estimated that in the U.S. alone approximately 6,000 computers are discarded every day. E-waste is also toxic, as electronics can include heavy metals, Mercury, Cadmium, and Lead. Switzerland was the first country to set up an electronic waste recycling system. This graph shows the amount in tons of e-waste collected in Switzerland from 1994 to 2006. Graph by deepali.
Rising U.S. Population
A study by the Metropolitan Institute at Virginia Tech predicts that the U.S. population will hit 1 billion between 2100 and 2120. This graph shows the yearly population change in the US since 1900. The last U.S. census conducted in 1999 counted the American population at 272,690,813, just under a third of the one billion mark. Currently the two most populated countries in the world are China with a population of 1.3 billion and India with 1.1 billion. The report suggests that America should begin changing the way we utilize urban space now so that we can accommodate the growing population in the future. Data uploaded by Suite22.
Has the housing market hit bottom?
A blog post on Arlington Condo points to current trends in local real estate as one way to look at the relation between the recession and the housing market in Arlington, Virginia. Some economists think the market has hit bottom and is close to stabilizing, while others forecast it won't hit bottom until later this year. This graph shows the original listing price and the final net close price for condos in Arlington. On average condos are selling at roughly an 8 percent reduction from the original listing price. When the difference between the original listing price and the final net close price (closing price minus seller concessions) begins to narrow, that’s when you know the bottom was reached.
