About half of Americans born at the turn of the 20th century had blue eyes, according to a 2002 Loyola University study in Chicago. By mid-century that number had dropped to a third. Today only about one 1 of every 6 Americans has blue eyes, said Mark Grant, the epidemiologist who conducted the study

in 1900, 50% of Americans had Blue eyes

as of 2015, 16.6% of Americans have Blue eyes


in 1900, over 35% of Americans had natural blonde hair, that has now declined to approximately 16%


in 1900, whites made up 87.9% of the USA
they now make up about 66%

the % of blue eyed and blonde haired people has fallen much more drastically than the decline of white people in the USA


which leads us to a dilemma, will blue eyes and blonde hair become extinct in the United States ?
if the trend continues than surely by around the year 2300, we wont have any more blue eyed or blonde haired people in the USA

or will their population stabilize ?
along with the white population ?

Brown is dominant - doesn't work like that. Most brown-eyed people have some blue-eyed genes in the line that will occasionally pop up.

Percentage decline doesnt equate to a population decline.

The US population grew 419% since 1900
The ratio of blue eyes in the US dropped 66.8%

So the total number of blue eyes has increased since 1900. Only at a very small number. Is the blue eye representation losing importance? Most definitely. Going extinct in the US? Not happening.

That's not how it works: dominant and recesssive

If there are any blue eye genes in a pool, even if no one in the group (say, the entire country) has blue eyes, babies will still be born with blue eyes.

Exactly. This is why I have a Mexican friend with green eyes and Armenian friends with blue.

I used to work with a woman who had brown hair and eyes. She was married to a black man who had brown eyes and hair. Their baby had blue eyes and fair hair. And yes, it was his baby. It's entirely possible.

I was born when nearly half the population had blue eyes, and they're still blue.

Perhaps, but the numbers are not there. Yet.
