What are contributing factors which affect population size?Our capacity to procreate is impacted by economics, knowledge, and health. A number of things contribute to population control. Birth control is crucial, and it can be accomplished by using particular techniques that work well alone or in combination. Prescription birth control or contraceptives are the first approach. Birth control must be available (accessible) in order for this strategy to work. The second is the possibility of governmental initiatives that either support or oppose people having and rearing children. Supports are the most popular government initiative for encouraging people to have children (for families with children). In contrast, a disincentive to raising big families, like direct taxes, would apply. I truly oppose forced family planning, like the one-child policy that China practiced for many years, but there are less restrictive ways to get the same result. The third category is personal economics. The decision to have children depends on your ability to support them financially. Unfortunately, it isn't the case in many third-world nations, where poverty and sickness are pervasive. I don't mean forcible control when I say that those countries need to do more to keep their populations under control. They must adopt human methods of population control utilizing tried-and-true procedures that don't effectively drive women into early pregnancy. It puts the fourth technique into action. The fourth strategy is instruction. Although it is an extremely effective method, the secret to effective birth control education is to make it accessible by putting in place the infrastructure required to have an impact. It needs to be publicized to achieve acceptance and sustainably funded to ensure longevity. Emigration and immigration are the final two strategies I'll mention. Through collaboration with nations that depend on immigration for the growth of their economies, nations with excessive populations can develop strategies for population emigration. As long as there is a desire to develop and implement solutions, there are many options. Migration will continue as long as there is war and poverty because the world is a large place and boundaries are artificial. By eliminating those factors, educating people, and promoting responsible family planning, you can control the population. possibly during our lifetime.
