While being a single parent can certainly be very rewarding, it can also be difficult. Especially in situations where the noncustodial parent is not paying child support.
A study that looked at the involvement a noncustodial father has with his children pointed to one of the biggest factors coming down to how far away he is living from his kids. This distance can be due to the father choosing to live farther or closer, but also if the mother decides to relocate the children.
With a downed economy it could be harder to keep a job or even find a job, and because of this, children are suffering financially if their non-custodial parent can either not afford to pay child support, or is paying a lot less than he or she used to.
