The Williston Herald describes the Census Bureau’s estimate of 2011 population for North Dakota and key cities in their article Census estimates indicate growth in ND oil patch.
The article says the official estimates are that Williston and Watford City grew by 9% in 2011.

I took a quick look and concluded the pace of change is outrunning the Census Bureau’s ability to track the small-level detail.
For example, here is the estimate for Williston: 2010 population – 14,824; 2011 population – 16,006
Here is the total for Williams county, where Williston is located – 2010 population – 22,560; 2011 population – 24,374
I’m a long distance away, but I can tell from here that those estimates are far too low. The real growth curve is far above 9%.
