I tried to find out what numbers Google were using, but I can't find your quote on the page you link to? Edit: ah it's from the article.

You must be mistaken. It's well known that the USA was conceived as a "melting pot nation", a nation of immigrants, and those agitating for the opposite are rightly rebuked as un-American. Diversity is our strength, e pluribus unum, etc.
That is simply not compatible with ever having had white-only immigration laws, let alone so recently that it would still affect the age-structure.
We have a long and illustrious history of discriminating against different races, when it comes to immigration. Just to list a few examples:
https://en.wikipedia.org/wiki/Naturalization_Act_of_1790
"The law limited naturalization to "free white person(s) ... of good character", thus excluding Native Americans, indentured servants, slaves, free blacks and later Asians, although free blacks were allowed citizenship at the state level in a number of states." (note that Dred Scott v Sanford later explicitly declared that black people couldn't receive citizenship.)
https://en.wikipedia.org/wiki/Chinese_Exclusion_Act
(followup to the Page Act of 1875, which banned Chinese women so Chinese male laborers who came over to build the railroads wouldn't reproduce.)
https://en.wikipedia.org/wiki/Immigration_Act_of_1924
"The Immigration Act of 1924 ... prevented immigration from Asia, set quotas on the number of immigrants from the Eastern Hemisphere, and provided funding and an enforcement mechanism to carry out the longstanding ban on other immigrants."
Only in 1952 with the McCarran-Walter Act was this exclusion on Asian immigrants lifted, and the National Origins Formula (attempting to keep the racial composition status quo) was in place until 1965.
I am only highlighting that the oft-repeated claim that America was conceived as a nation of non-discriminatory immigration is a lie. It only moved in that direction with the Immigration and Nationality Act of 1965.
But I sense you're having fun being so vaguely edgy and contrarian so I don't want to further encourage it.
