Final answer:
Developing countries most commonly use family planning and education to control population growth, aiming to lower the fertility rate and manage the population effectively.
Step-by-step explanation:
The most common strategy adopted by developing countries to deal with the problem of population growth is through policies and educational programs focused on family planning and reducing the fertility rate. These efforts are crucial in addressing the paradox whereby declining growth rates still result in substantial population increases due to the large base population. Developing countries often implement national and regional policies to encourage family planning, such as in India, and develop initiatives meant to increase educational outreach on the benefits of family planning to manage population growth more effectively.
Through the process of demographic transition, countries typically experience a shift from high birth and death rates to lower rates as they develop economically. Strategies to lower birth rates are aimed at achieving a sustainable population size and include offering incentives, improving healthcare, and public health measures, such as vaccinations to reduce child mortality. Efforts to manage population growth take into account deeply personal and cultural beliefs, which can sometimes be at odds with state policies.
