This seems pretty accurate to me. From Business Insider (Australia): 
In his fourth book, “American Nations: A History of the Eleven Rival Regional Cultures in North America,” award-winning author Colin Woodward identifies 11 distinct cultures that have historically divided the US.
“The country has been arguing about a lot of fundamental things lately including state roles and individual liberty,” Woodward, a Maine native who won the 2012 George Polk Award for investigative reporting, told Business Insider.
“[But] in order to have any productive conversation on these issues,” he added, “you need to know where you come from. Once you know where you are coming from it will help move the conversation forward.”
Here’s how Woodward describes each nation:
YANKEEDOM:
Encompassing the entire northeast north of New York City as well as parts of Michigan, Wisconsin, and Minnesota, Yankeedom values education, intellectual achievement, communal empowerment, and citizen participation in government as a shield against tyranny. Yankees are comfortable with government regulation. Woodward notes that Yankees have a “Utopian streak.” The area was settled by radical Calvinists.NEW NETHERLAND:
A highly commercial culture, New Netherland is “materialistic, with a profound tolerance for ethnic and religious diversity and an unflinching commitment to the freedom of inquiry and conscience,” according to Woodward. It is a natural ally with Yankeedom and encompasses New York City and northern New Jersey. The area was settled by the Dutch.THE MIDLANDS:
Settled by English Quakers, The Midlands are a welcoming middle-class society that spawned the culture of the “American Heartland.” Political opinion is moderate and government regulation is frowned upon. Woodward calls the ethnically diverse Midlands “America’s great swing region.” Within the Midlands are parts of New Jersey, Pennsylvania, Ohio, Indiana, Illinois, Missouri, Iowa, Kansas, and Nebraska.TIDEWATER:
Tidewater was built by the young English gentry in the area around the Chesapeake Bay and North Carolina. Starting as a feudal society that embraced slavery, the region places a high value on respect for authority and tradition. Woodward notes that Tidewater is in decline today, partly because “it has been eaten away by the expanding federal halos around D.C. and Norfolk.”GREATER APPALACHIA:
Colonised by settlers from the war-ravaged borderlands of Northern Ireland, northern England, and the Scottish lowlands, Greater Appalachia is stereotyped as the land of hillbillies and rednecks. Woodward says Appalachia values personal sovereignty and individual liberty and is “intensely suspicious of lowland aristocrats and Yankee social engineers alike.” It sides with the Deep South to counter the influence of federal government. Within Greater Appalachia are parts of Kentucky, Tennessee, West Virginia, Arkansas, Missouri, Oklahoma, Indiana, Illinois, and Texas.DEEP SOUTH:
The Deep South was established by English slave lords from Barbados and was styled as a West Indies-style slave society, Woodward notes. It has a very rigid social structure and fights against government regulation that threatens individual liberty. Alabama, Florida, Mississippi, Texas, Georgia, and South Carolina are all part of the Deep South.EL NORTE:
Composed of the borderlands of the Spanish American empire, El Norte is “a place apart” from the rest of America, according to Woodward. Hispanic culture dominates in the area, and the region values independence, self-sufficiency, and hard work above all else. Parts of Texas, Arizona, New Mexico, and California are in El Norte.THE LEFT COAST:
Colonised by New Englanders and Appalachian Midwesterners, the Left Coast is a hybrid of “Yankee utopianism and Appalachian self-expression and exploration,” Woodward says, adding that it is the staunchest ally of Yankeedom. Coastal California, Oregon, and Washington are in the Left Coast.THE FAR WEST:
The conservative west. Developed through large investment in industry, yet where inhabitants continue to “resent” the Eastern interests that initially controlled that investment. Among Far West states are Idaho, Montana, Wyoming, Utah, Washington, Oregon, North Dakota, South Dakota, Colorado, Nevada, Utah, Nebraska, Kansas, Arizona, New Mexico, and California.NEW FRANCE:
A pocket of liberalism nestled in the Deep South, its people are consensus driven, tolerant, and comfortable with government involvement in the economy. Woodward says New France is among the most liberal places in North America. New France is focused around New Orleans in Louisiana as well as the Canadian province of Quebec.FIRST NATION:
Comprised of Native Americans, the nation enjoys de facto independence by being far in the North. Woodward says the territory of the First Nations is huge, but its population is less than 300,000, most of whom live in the northern reaches of Canada.
