DoB calculation from Census Age

Post by GladToBeGrey » 06 May 2010 14:42

AS (like GC before it) can calculate and create BIRT events based on the stated age in the census.

For UK censuses (Leave aside UK 1841 for the moment) age is given either in whole months (up to 11) or otherwise in whole years.

So someone aged 9yrs in the 1851 census (taken on 30th March 1851) could have been born anywhere between 1st April 1841 and 30th March 1842.  However, unless I've missed a setting/option somewhere, AS calculates a single date of 1841 (cal).  

AS already does such a calculation for persons aged in months (e.g. 3mo at 1851 census calculates a DoB of December 1850).

Could the already excellent AS be further enhanced to calculate the range for ages given in years (as it already can for 1841 for different reasons)?

Perhaps it could be an option to calculate either a single year DoB (as now) or the range.

Cheers; John.

I'ved added it to the (AS) wishlist.

The reason I don't like it is that in Family Historian (and GEDCOM) you can't record that a between date is calculated (or estimated or approx.). When I see a birthdate as being 1841(cal) I know that it can't be totally trusted as it is calculated from another date. In my experience census dates are frequently wrong and the 9 year old in your example could easily be 8 or 10. If however the birth date is recorded as being 'between 1st April 1841 and 30th March 1842' it implies that it is certain that the date is in that range.

I ought to add I'm not entirely happy about using the date range for 1841 census either (for the same reason) but as the calculated dates can be so far out it does make some sense.

If it could be recorded as 'between 1st April 1841 and 30th March 1842 (calculated)' then I'd be happy (and would probably have had this as the default setting!).

Cheers
