Because "current residents" also include the children and teenagers currently living there? You act like young adults are 100% flown in by storks, as if the city doesn't itself procreate, as if school children doesn't grow up into young adults.
Any good sources showing how much various cities' fertility rate contributes to their population growth?
They don’t contribute, as they are all below replacement rate.

Probably true worldwide except maybe Africa and Middle East.
