Are there risk factors for children & youth when families constantly move from place to place?

I ask this because I've noticed there are many people who are on Social Assistance who move around constantly, especially when young children are involved. I'm wondering, if there are possible risk factors that can be developed among children & youth down the road? How can moving around constantly affect them later on, i.e. lack of stability etc. I'm not trying to be quick to judge, because who knows what went on however am wondering as my boyfriend has studied Youth Corrections & Interventions at Durham College.
