Most people that move into or out of Simpsonville, do so in the summer. This might be due to the ease of moving with children since they are no longer in school. Additionally, the weather might be another reason why people move to the city at that time of the year. Summertime is a warm time, and that is important for an activity like moving. The challenge with moving in the summer is that the demand for movers complicates the process and increases the cost of moving.
