Population between 2 dates

[#1]

I have a table of people with a date of Birth and a date of death if the person is deceased.

I want to be able to select a range of dates and have a counter of population alive during that period.

I guess the way QV works, I need to generate a table containing a person alive for each date that exists between the earliest DOB and today.

How can I script this?

My table people table has

person_id,

date_of_birth,

date_of_death

Thank you !
