When most people think of Nevada, they usually think about Las Vegas, and it turns out that tourism is one of the state's main industries. That's usually okay so long as there are other good jobs. In Nevada, you're pretty limited when it comes to employment, which is why a lot of people are choosing to move out of the state. This is truer in rural areas, where there are way fewer options.
The state's education system also isn't the greatest, which is another reason that many with families are choosing to leave for places like Arizona or California. In addition, the unemployment rate is among the worst in the entire country.
