As this millennium is currently in progress, its first two decades of 21st century (the past 2000s and the current 2010s), are the subject of the historian's attention.

- According to the UN Population Bureau, life expectancy in 2200 is predicted to be around 100 for developed countries and the world population is estimated to be about 8.5 billion. The UN says that these projections could be invalidated by changes and progression 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. 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.
