World Population: 10.5 Billion (+/- 1 Billion)

2100: 75 Years From Now
3 Generations From Now (from 2020 CE)

This estimate aligns with the medium-variant projection from major demographic studies like those conducted by the United Nations, which predict that the population could be between approximately 9.3 billion and 11.3 billion by the end of the century.

Michael Alan Prestwood
Author & Natural Philosopher

Prestwood writes on science-first philosophy, with particular attention to the convergence of disciplines. Drawing on his TST Framework, his work emphasizes rational inquiry grounded in empirical observation while engaging questions at the edges of established knowledge. With TouchstoneTruth positioned as a living touchstone, this work aims to contribute reliable analysis in an emerging AI era where the credibility of information is increasingly contested.
