This prediction concerns China’s population in the year 2100. As of today (November 30, 2025), that year has not occurred, so it is impossible to determine whether the prediction has come true.

We do have long‑range demographic projections suggesting large declines in China’s population by 2100—many major forecasts now project China falling well below 1 billion, and some scenario ranges can go down toward roughly half of its peak. However, these are still projections, not outcomes, and demographic forecasts over ~75 years carry significant uncertainty due to possible changes in fertility policy, migration, mortality, and economic conditions.

Because the target year (2100) is still in the future, the correctness of the statement that China will have “about 600 million people” by then cannot yet be evaluated. Therefore the only defensible status is: too early to tell.
