A study scheduled to be released this week says the number of homeless people in North Dakota without shelter (966) has exceeded the number of state residents in emergency shelters (807), the Associated Press reports.

The survey was taken in July 2011 and the report was assembled by the North Dakota Coalition for Homeless People.

The report cites a housing shortage that has spilled across the state from western North Dakota, where record oil production has created new jobs and drawn thousands.
