- Optimum population
The optimum population is the size of a population that is optimal. There are, however, various opinions on what "optimal" means in this usage, resulting in various end-targets for it, but estimations usually take ecological sustainability and carrying capacity more or less into account. Also, optimum population can refer to a specific area, such as a region or country, but can also refer to the entire world or universe.
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.
Various end-targets are often balanced together in estimating the optimum human population, and different emphasis on different end-targets cause variability among estimates.
- Decent wealth and resources to everyone
- Basic human rights to everyone
- Preservation of cultural diversity
- Allowance of intellectual, artistic, and technological creativity
- Preservation of biodiversity
Based on this, the estimation of optimum population was to be roughly around 1.5 billion to 2 billion people.
