You meant "affect" and not effect. It did many things that would be hard to list in one post. Really, if you wiki gold rush you can see history and trends resulting from it. But in short it established a large American presence in the west; much quicker than if there wasn't one. This then allowed for new forms of trade and merchants to develop.

The California gold rush was in 1849, it effected California's population by all of the immigrant miners coming to find gold, later on admitting California as a state in 1850.
The Gold Rush made the population of California grow immensely. It was the sole reason why California was able to apply for statehood.
