During the Gold Rush, the population of California increased a great deal. The original population of California was around 12,000 people before the gold rush. After the discovery of gold all of the adventurers and people who wanted to get rich decided to make the long journey across America to California and attempt to strike it rich easily and quickly. The population grew to over 100,000 people. Along with the people who came to find gold came the people who built stores to sell equipment and supplies to the prospectors. Just like today, if an area has a lot of jobs many people move to that area to get a job which brings new stores, new houses, and new opportunities.
