Charles Platt just wrote to cryonet:


Currently on my web site at is a population
similation program that allows the user to vary birth rate, death rate,
and maximum lifespan, and see the impact on total US population during the
next 100 years. The program runs on any MS-DOS or Windows computer.

I wrote this program after I was unable to find any demographic authority
who had considered the possible impact of a change in maximum lifespan.

My unsurprising conclusion is that since the birth rate compounds itself
(more children have more children), it is always a more powerful
determinant of population than changes to the death rate, including
changes caused by a lengthened maximum lifespan. To take the most extreme
case: If maximum biological lifespan becomes infinite, while the birth
rate decreases to zero, total population would still gradually decrease as
a result of accidental death.


Have fun! This might add some rigor to the discussion.
