The vital coefficients (a and b) that I provided were for the global population. If you wish to examine a particular population subset, then different parameters apply. For example, the United States has a=0.03134 and b=1.5887E-10. For the United States, zero population growth will be reached when the population reaches about 400 million.

You are partially right in mentioning China and India. Backwards countries that become industrialized have not fit this model very well because a more efficient use of resources will affect the parameters. However China has instituted severe population control policies that are offsetting the industrialization of these two countries; they probably wash each other out, and the global population prediction is still valid.

Look, either your formula is accurate or it isn't. Either I am right or I am wrong. Either your faith in the forumula is justified or it isn't.

You lofted the forumula. I observed that it isn't accurate due to the examples given. You stated, "Yes but." Sorry, nice try.
