[Branson, Steven S]

Effectively only 4% die, 4% become children and 92% remain adults. Total = 100%.

My best student came to me with the same problem

The value for the transitions for adults should be 92% remain adults, 8% die and 4% produce children.  These do not add up to 100% as the population increases due to adults having children and decreases due to people dying.
