True but wrong -- start with a stable population where the birth rate and death rates are equal. Then increase the life span by 20% and wihat happens?

The death rate will have decreased resulting in population growth.

The biggest example is China's attempt to lomit their population growth woth the "one child" policy. If I recall the open source article correctly, their population would have doubled over 50 years eaven if every family was limited to just one child.

Over the longer term, however, the "one child" policy would cause a dramtic decline in population.

The time constant of a few generations makes figuring these things out a bit challenging.

Since firstbornes are usually males it starts feeding on itself too, they are getting a very lopsided population out of the deal with fewer females. Fewer couples = fewer firstborns in the next generation... and then the process repeats.
