billion people have been born throughout history — that is the demographers' count, and everyone alive is inside it. The registry is built with room to spare: the free records will last more than five centuries — for everyone yet to be born. Your record is fixed by your day of birth and already sits in its place: a number is computed, not issued — it costs nothing and it is permanent.
The count is kept. The record will not be lost.
The scale runs to the registry ceiling — two hundred billion records. The empty part is not a gap in the data: those are free records for people not yet born.
≈ 109.34B have already lived their lives. The rest are living now — and you are among them.

The last complete decade is the most populous in history: the 2010s produced more births than any decade before them. The evenness of the neighbouring rows is not rounding — the annual number of births worldwide is close to its early-1980s level, and it peaked in 2012. UN estimate, World Population Prospects 2024.
Every figure in the breakdown is computed from the same cumulative table that issues the numbers — the breakdown matches the counter to the last digit.
Decades start at 1950: before that the demographic anchors sit further apart than ten years, and splitting between them would show a precision we do not have. Everything before 1950 is one row — and the search by date of birth finds your place inside it: it works for any past date.
