Copper Production & Population Growth

Copper is an essential metal for modern civilization. While often working behind the scenes, it is a fundamental component in everything from household wiring to advanced electronics. An analysis of its production over the last century reveals a compelling story. As the global population has grown, so has the demand for copper.

More recently, however, its production trajectory has accelerated, reflecting a growing global need for connectivity, advanced technology, and new forms of energy. As the book "RED METAL, BLUE PLANET" illustrates, key moments in recent history have highlighted this growing demand.

The Industrial Baseline: A Parallel Growth

For much of the 20th century, copper's story was closely linked with basic industrial development. As global populations expanded and societies built out their infrastructure, the demand for copper increased at a similar, steady pace. This period showed a parallel growth between population and copper use. Homes needed wiring and pipes, cars required electrical systems, and factories used copper components.

The Digital Accelerator: More Copper Per Person

A notable shift began in the mid-1960s, and then accelerated in the mid-1990s. The "Digital Revolution," with the widespread adoption of personal computers, the internet, and early mobile phones, created new and significant demands for copper.

This wasn't just about more people; it was about more copper per person. Each new electronic device and the data infrastructure to support it added to the global copper requirement. This trend was amplified by the "Rise of a New Consumer" in 1999. China's rapid industrialization and urbanization, in particular, drove substantial new demand for construction materials, electronics, and infrastructure, creating a strong "super-cycle" for copper that pushed production levels higher.

Supply Challenges

Unlike in the past—such as the 1990s “supply flood” from Chile—today’s supply growth faces tougher conditions. New high-grade deposits are harder to find, ore grades are declining, and mine development takes longer due to regulatory hurdles.

This growing imbalance highlights the need for greater efficiency, recycling, and continued investment in mining innovation.
