* All citizens of Canada are classified as “Canadians” as defined by Canada’s nationality laws. However, since 1996 “Canadian” as an ethnic group has been added to census questionnaires for possible ancestry. The majority of respondents to this selection are from the eastern part of the country that was first settled. Respondents generally are visibly European (Anglophones and Francophones), however no-longer self identify with their ethnic ancestral origins.
By far the largest ancestral group, stretching from coast to coast across 21st century America is German, with 49,206,934 people. The peak immigration for Germans was in the mid-19th century as thousands were driven from their homes by unemployment and unrest.
The majority of German-Americans can now be found in the the center of the nation, with the majority living in Maricopa County, Arizona and according to Business Insider, famous German-Americans include, Ben Affleck, Tom Cruise, Walt Disney, Henry J. Heinz and Oscar Mayer.
Indeed, despite having no successful New World colonies, the first significant groups of German immigrants arrived in the United States in the 1670s and settled in New York and Pennsylvania.
Germans were attracted to America for familiar reasons, open tracts of land and religious freedom and their contributions to the nation included establishing the first kindergartens, Christmas trees and hot dogs and hamburgers.
41,284,752 Black or African Americans
The census map also identifies, Black or African-American as a term for citizens of the United States who have ancestry in Sub-Saharan Africa.
The majority of African Americans are descended from slaves from West and Central Africa and of course have become an integral part of the story of the United States, gaining the right to vote with the 15th amendment in 1870, but struggling with their civil rights for at least another century.
Predominantly living in the south of the nation where they were brought to work on the cotton plantations and as slaves in the late 18th to mid-19th centuries, Black or African Americans also have sizable communities in the Chicago area of Illinois and Detroit, Michigan.
Another group who joined the great story of the United States were the Irish and the great famine of the 1840s sparked mass migration from Ireland.
It is estimated that between 1820 and 1920, 4.5 million Irish moved to the United States and settled in the large cities like New York, Boston, Philadelphia, Chicago and San Francisco.
Currently, almost 12 percent of the total population of the United States claim Irish ancestry – compared with a total population of six and a half million for the Republic of Ireland and Northern Ireland today.
Irish residents of note include John F. Kennedy, Derek Jeter and Neil Armstrong and 35,523,082 people call themselves Irish.
And from 1990 to 2000, the number of people who claimed Mexican ancestry almost doubled in size to 31,789,483 people.
Those with Mexican ancestry are most common along the Southwestern border of the United States and is largest ancestry in Los Angeles, Houston, Phoenix, San Diego, Dallas and San Antonio.
The next largest grouping of people in the United States by ancestry are those who claim to be English-American.
Predominantly found in the Northwest and West, the number of people directly claiming to be English-American has dropped by 20 million since the 1980 U.S. Census because more citizens have started to identify themselves as American.
They are based predominantly in the northeast of the country in New England and in Utah, where the majority of Mormon immigrants moved in the middle 19th century.
Notable American people with English ancestry are Orson Welles and Bill Gates and 26,923,091 people claim to come from the land of the original Pilgrims.
The surprising number of people across the nation claiming to have American ancestry is due to them making a political statement, or because they are simply uncertain about their direct descendants. Indeed, this is a particularly common feature in the south of the nation, where political tensions between those who consider themselves original settlers and those who are more recent exist.
One of the most influential nationalities to migrate in large numbers to the United States were the Italians.
Between 1880 and 1920, more than 4 million Italian immigrants arrived in the United States forming ‘Little Italies’ wherever they went.
Bringing their food, culture and entertainment to the nation, another large wave of Italian immigrants arrived in the country following WWII, bringing the total number today to 17,558,598 people.
The largest of the Slavic groups to live in the United States, Polish Americans were some of the earliest Eastern European colonists to the New World.
Up to 2.5 million Polies came to the United States between the mid-19th century and World War 1 and flocked to the largest industrial cities of New York, Buffalo, Cleveland, Milwaukee and Chicago.
In many states, the Hispanic population doubled between the 2000 and 2010 census. In New Mexico, Hispanics outstripped whites for the first time, reaching 46 per cent compared to 40 per cent.
Historically, along with the English, the French colonized North America first and successfully in the North East in the border areas alongside Quebec and in the south around New Orleans and Louisiana.
