The overall human death rate is not likely to change significantly in the foreseeable future. It will presumably decline in nations like Russia which have recently suffered sociopolitical upheavals. The opposite trend can be expected for developing nations as their youthful populations age. Globally, birth rates will probably continue to decline in the coming decades since, nowadays, couples are increasingly prone to limit their family size, whatever their wealth. Coercion by national governments, such as Chinas one-child policy, appears to be unnecessary. If and when the global birth rate again matches death rate, we will hit zero population growth.
