When is the week we want to get to for higher baby survival if born early?

Sorry I don't know how else to put it...I don't remember what it is from my first pregnancy...is it like 24 weeks or something like that?  Looking for the magic number that ups the baby's survival rate if born early...and the number 24 sticks out in my head!

Just wondering what it was if you know, thank you!
