In 2008, 4.05 million parents were living with an adult child. By the end of 2011, the number had risen to 4.6 million — a 13.7 percent increase. This is a growing trend, so it’s important to know that you’re not alone in this journey. One of the main reasons parents are living with their adult children is because of rising senior care costs and demands. Although it might be difficult at first, a little cooperation and communication can go a long way when it comes to living with and caring for an elderly parent.
