[25] According to estimates by Thomas L. Purvis (1984), published in the European ancestry of the United States, gives the ethnic composition of the American colonies from 1700 to 1755.

[26] The ancestry of the 3,929,214 population in 1790 has been estimated by various sources by sampling last names in the very first United States official census and assigning them a country of origin.

[15] There is debate over the accuracy between the studies with individual scholars and the Federal Government using different techniques and conclusion for the ethnic composition.

[28] The 1909 Century of Population Growth report came under intense scrutiny in the 1920s; its methodology was subject to criticism over fundamental flaws that cast doubt on the accuracy of its conclusions.

In 1927, proposed immigration quotas based on CPG figures were rejected by the President's Committee chaired by the Secretaries of State, Commerce, and Labor, with the President reporting to Congress "the statistical and historical information available raises grave doubts as to the whole value of these computations as the basis for the purposes intended.

The diaspora is concentrated in countries that had mass migration such as the United States (as well as Canada, Australia, New Zealand, South Africa and Zimbabwe) and that are part of the English-speaking world.

The 1783 Treaty of Paris represented Great Britain's formal acknowledgment of the United States' sovereignty at the end of the American Revolutionary War.

[citation needed] The vast majority of the Founding Fathers of the United States were of mixed British extraction.

Many of the prewar WASP elite were Loyalists who left the new nation, some moving north to the Canadian colonies which remained under British rule.

[62] Linda Colley, a professor of history at Princeton University and specialist in Britishness, suggested that because of their strong colonial influence on the United States, the British find Americans a "mysterious and paradoxical people, physically distant but culturally close, engagingly similar yet irritatingly different".

[63] For over two centuries (1789–2009) of early U.S. history, all Presidents with the exception of two (Van Buren and Kennedy) were descended from the varied colonial British stock, from the Pilgrims and Puritans to the Scotch-Irish and English who settled Appalachia, with more recent presidents such as Joe Biden and Donald Trump having partial British ancestry.

Colonial ties to Great Britain spread the English language, legal system and other cultural attributes.

[65] Historian David Hackett Fischer has posited that four major streams of immigration from the British Isles in the colonial era contributed to the formation of a new American culture, summarized as follows: Fischer's theory acknowledges the presence of other groups of immigrants during the colonial period, both from the British Isles (the Welsh and the Highland Scots) and not (Germans, Dutch, and French Huguenots), but believes that these did not culturally contribute as substantially to the United States as his main four.

Apple pie – New England was the first region to experience large-scale English colonization in the early 17th century, beginning in 1620, and it was dominated by East Anglian Calvinists, better known as the Puritans.

Baking was a particular favorite of the New Englanders and was the origin of dishes seen today as quintessentially "American", such as apple pie and the oven-roasted Thanksgiving turkey.

[71] Baseball – The earliest recorded game of base-ball for which the original source survives, involved the family of George II of Great Britain, played indoors in London in November 1748.

[72] The English lawyer William Bray wrote in his diary that he had played a game of baseball on Easter Monday 1755 in Guildford, also in Surrey.

[79] The design consisted of 13 stripes, red and white, representing the original Thirteen Colonies, the canton on the upper left-hand corner bearing the British Union Flag, the red cross of St. George of England with the white cross of St. Andrew of Scotland.

The flag was first flown on December 2, 1775, by John Paul Jones (then a Continental Navy lieutenant) on the ship Alfred in Philadelphia).
