hOW many people were born and how many of them died during the last 1000 years?

Approximately, on a rough estimate, it may be few million people - plus or minus. Even if there is any slight change it may be only few percentage here an there. Minor deviations accepted.

For your kind information, I am telling this information only in respect to our own country. In other countries, the figures may differ.

It is impossible to calculate how many were born in thr last thousand years with any degree of accuracy, but one can say with certainty that all of them have died except the approximately 6.8 billion currently living.
