How an oil boom brought diversity to North Dakota; CNN, 2/2/15

Steve Hargreaves, CNN; How an oil boom brought diversity to North Dakota:

"Ten years ago there were three black people working in North Dakota's oil fields. Not three percent, just three people.

Now there are over 600.

Many of them came for jobs working in the Bakken oil fields, and settled in towns like Williston, N.D.

Like the state itself, most people in this oil boomtown are white. But it's impossible not to notice the number of minorities -- particularly blacks -- among the huge influx of oil workers that's descended upon the region over the last few years. And while the recent fall in oil prices has called the longevity of the boom into question, at least some of these workers are here to stay."
