===Population in 1790===
According to ''The Source: A Guidebook of American Genealogy'', by Kory L. Meyerink and Loretto Dennis Szucs, the following were the countries of origin for new arrivals coming to the United States before 1790. The regions marked * were part of, or ruled by, the Kingdom of Great Britain (the United Kingdom of Great Britain and Ireland after 1801). The ancestry of the 3,929,326  population in 1790 has been estimated by various sources by sampling last names in the 1790 census and assigning them a country of origin.

According to the Harvard Encyclopedia of American Ethnic Groups (Thernstrom, S 1980, "Irish," p.&nbsp;528), there were 400,000 Americans of Irish birth or ancestry in 1790; half of these were descended from Ulster, and half were descended from other provinces in Ireland.

==== 1790 population of Scotch-Irish origin by state ====
The [[United States Census Bureau|Census Bureau]] produced official estimates of the colonial American population with roots in the [[Provinces of Ireland|Irish province]] of [[Ulster]], in collaboration with the [[American Council of Learned Societies]], by scholarly classification of the names of all [[White Americans|White]] heads of families recorded in the [[1790 United States census|1790 Census]]. The government required accurate estimates of the origins of the population as basis for computing [[National Origins Formula]] immigration quotas in the 1920s (i.e. how much of the annual immigrant quota would be allotted to the [[Irish Free State]], as opposed to [[Northern Ireland]] which remained part of the [[United Kingdom]]). The final report estimated about 10% of the U.S. population in 1790 had ancestral roots in [[Ireland]], about three fifths of that total from Ulster–broken down by state below:
