The statistics page sets out certain summary data from the database.

Note that you can choose any one tree or all trees.

Note the footnote: Age-related calculations are based on individuals with recorded birth and death dates. Due to the existence of incomplete date fields(e.g., a death date listed only as "1945" or "BEF 1860"), these calculations cannot be 100% accurate.

There are birth years prior to 1000 but so far I have not found a way to get either Reunion to export 3-digit years as 4 or the web-site to,interpret 3-digit figures as 4 when it creates what is known as a true date. I have tried manually editing the database where the true date is stored, but this gets overwritten every time I update the data. I cannot enter a 3-digit year with a preceding "0" because both Reunion and TNG strip it from what is saved. Neither the Reunion nor TNG support groups have been able to provide a solution (mainly because the 3-digit years should convert to true dates), so if anybody has any suggestions for fixing this, I would be most grateful!
