For Humans
Regarding the human population, end-targets for an optimum population include ecological sustainability, economic output and philosophical or ethical ends-in-themselves.
Some commentators disagree with the concept of "optimum population", believing that the human population will always, in the long-term, be able to adapt to the requirements of a larger population. Others do not believe it is a helpful concept as any calculation will always be plagued with assumptions, as well as unverifiable predictions, even if it could theoretically exist.
To reach an optimum population, a country must be able to measure human welfare and environmental impacts, as well as having policies in place to influence the fertility rate and net migration. This implies agreement on welfare, environmental issues, accurate projections of immigration, age distribution and changes in lifespan among other factors. Reaching optimum population is an important objective in the wider project of creating a sustainable society.
