Module 05
Each of these has a published value for the year you were born and a published value for now. The difference is measured from your beginning rather than from a round-numbered year.
Annual values, interpolated to your date. The series themselves are not measured daily, and a figure that pretended otherwise would be inventing precision.
The living counter carries the most recent annual figure forward at the rate of the last two years. It is an estimate between measurements, not a census.
Every figure is listed with its source and the year it was retrieved, so it can be checked.
