September 11 attacks
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks.
New York City
In the 1970s, job losses due to industrial restructuring caused New York City to suffer from economic problems and rising crime rates. While a resurgence in the financial industry greatly improved the city's economic health in the 1980s, New York's crime rate continued to increase through that decade and into the beginning of the 1990s. By the mid 1990s, crime rates started to drop dramatically due to revised police strategies, improving economic opportunities, gentrification, and new residents, both American transplants and new immigrants from Asia and Latin America. Important new sectors, such as Silicon Alley, emerged in the city's economy. New York's population reached all-time highs in the 2000 Census and then again in the 2010 Census.
The city suffered the bulk of the economic damage and largest loss of human life in the aftermath of the September 11, 2001 attacks. Two of the four airliners highjacked that day were flown into the twin towers of the World Trade Center, destroying them and killing 2,192 civilians, 343 firefighters, and 71 law enforcement officers. The North Tower was subsequently the tallest building ever to be destroyed and still is. The rebuilding of the area, has created a new One World Trade Center, and a 9/11 memorial and museum along with other new buildings and infrastructure. The World Trade Center PATH station, which had opened on July 19, 1909 as the Hudson Terminal, was also destroyed in the attack. A temporary station was built and opened on November 23, 2003. An permanent rail station designed by Santiago Calatrava, the World Trade Center Transportation Hub, the city's third-largest hub, was completed in 2016. The new One World Trade Center is the tallest skyscraper in the Western Hemisphere and the sixth-tallest building in the world by pinnacle height, with its spire reaching a symbolic in reference to the year of U.S. independence.
