Is it true that every time someone dies, a baby is born somewhere?

I don’t know I always wonder if there is any link between someone dying somewhere and some baby getting born somewhere else at the same time. What does astrology say?

Yes, that is totally true, but not exactly how you may be thinking of it.
The world is gigantic. There is currently about 7.8 billion people on earth. To put that in perspective, think of how much money you have in the bank, and how long it would take to count every dollar. If you have 1000, it would take about 15 minutes to count up to that. If you had a million, it would take just over 11 days to count every single one… if you had a billion, it would take around 32 years to count.
That means, to count every single person on the planet, at 1 second per person, it would take nearly 250 years to count them all. Thats a hell of a lot of people.
Since we have such a giant number of people, around the world, there are aprox. 15,000 births per hour. That means that about 4 babies are born every second. At the same time, there are about 6300 deaths per hour, or 1.75 per second.
That means, that every time someone dies, there are about 2.5 children being born at the exact same time.

No, it is NOT true.
For every person that dies there are approximately 2.4 births.
Since you obviously have some ulterior reason for asking this question, suffice to say that on any given day, the world’s population increases by about 225000.

This may or may not happen.
Considering the increasing (actually exploding) population of human and animals becoming distinct, a lion might get born as a human in this life.
In fact, there must be at least one species which is vanishing at a very high rate.
Crazy math nobody will actually bother to do ever.
So, Nobody knows.
Clearly. No one.
We can only guess such questions. No, yes, maybe…
But one thing is for sure.
“every time some “human” dies “on “this earth”, a “human baby” is born somewhere? is a false statement.

No. The human population is currently increasing and, in general, has been doing so for many thousands of years because more babies are born than people die. At some point in the future there will be population stasis, because growth cannot go on indefinitely, and this will probably be followed by population decline; but for how long is just guesswork.
