Sacramento is America’s most diverse city. While other cities like New York City or Los Angeles are diverse as well, the different cultures in Sacramento blend more smoothly together meaning that it’s also one of the most integrated countries in the nation as well. Sacramento is known for being an environmentally friendly city. Thanks to their energy distribution system, SMUD, the city has become a leader in use and the development of clean fuel sources. Sacramento built itself during the Gold Rush. Without the gold rush, it is far less likely that Sacramento would be the capital of California and the sixth biggest city in the state. The city was a very important distribution hub, allowing Sacramento to grow commercially very quickly.
