what was the population of earth during the Copper age

The world population during the Copper Age was very small by modern standards—roughly a few million people , with one cited estimate placing it at about 10 million during the Bronze Age , which followed the Copper Age. The Copper Age itself is usually placed around the 5th to 3rd millennium BCE , so the global population was likely below that Bronze Age level and still in the low-millions range.

Quick context

The Copper Age, also called the Chalcolithic, was a transitional period when people began using copper tools alongside stone. Exact population totals are not known, because there were no censuses, so all figures for that era are estimates rather than precise counts.

Practical estimate

A reasonable way to think about it is:

• Early Copper Age: likely around 1–5 million people.
• Late Copper Age: possibly several million , trending upward toward Bronze Age numbers.
• Best caution: any single exact number would be misleading, because scholarly estimates vary widely.

Why it is hard to pin down

Population estimates this far back are built from archaeology, settlement size, food production, and demographic modeling, not records. That means the answer is less like a census figure and more like a historical range.

Bottom line

If you want one short answer, the Earth’s population during the Copper Age was probably in the low millions , not tens or hundreds of millions.
