You do INDEED have the ability to look it up yourself.
But since you cannot Google, Use AI, or are just fucking ignorant, I'll supply the answer for you.
But before that, why does the number matter?
How many children are born Blind?
Since you don't know, does that mean they don't exist or don't matter.
You are so fucking ignorant, it pains me to respond to you.
But you asked a question.
Here is the answer.
How common is intersex?
Intersex traits occur in approximately 1 in 1,500 to 1 in 2,000 births for conditions that are visibly apparent at birth. However, if you include all variations of intersex traits that might not be immediately noticeable (such as chromosomal differences like Klinefelter syndrome or Androgen Insensitivity Syndrome), estimates rise to about 1 in 100 to 1 in 200 people.
So while visibly noticeable intersex traits are relatively rare, broader intersex variations are not uncommon.
