In the early 1900s, Jerome was a booming mining town of nearly 15,000; after commercial mining ended in 1953, its population fell to roughly 400

In the 1880s, Jerome experienced a rapid population increase thanks to lucrative copper mining opportunities. Thousands flocked to this bustling community on Cleopatra Hill, creating a viable town. However, unstable conditions from underground activities led to challenges. The subsequent decline in copper prices and the onset of the Great Depression caused many to leave, but national recognition and community efforts later helped safeguard Jerome's heritage.
