In contemporary history, the third millennium is a period of time that according to official sources, such as the United States Naval Observatory, began on January 1, 2001, and will end on December 31, 3000, of the Gregorian calendar. This is the third period of one thousand years in the Anno Domini or Common Era.
Stephen Jay Gould argued that it is not possible to decide if the millennium began January 1, 2000, or January 1, 2001. The Associated Press reported that the third millennium began January 1, 2001, and also reported that celebrations in the US were generally more subdued at the beginning of 2001, compared to the beginning of 2000.
As this millennium is currently in progress, its first two decades, the past 2000s and the current 2010s, are the subject of the historian's attention. The remaining part of the 21st century and longer-term trends are researched in futures studies.

However, the UN has warned that these projections could be invalidated by any change and progress in future life extension technology and discoveries, as well as changes in future birthrates.
- 22nd century - In his book The Next 100 Years, American political scientist George Friedman predicts that as the century begins, an ongoing confrontation between an increasingly powerful Mexico and the United States will be taking place.[dubious ] Mexico will be an economically and militarily powerful country capable of challenging the United States, while a Mexican majority in southern regions of the United States will have made them a de facto extension of Mexico, with increasing secessionist sentiment. Both countries will be competing for dominance over North America, which will remain the international centre of gravity throughout the next few centuries.
