A population policy aimed at achieving zero population growth is most effective in a country with which type of population pyramid? a. Expansive b. Constrictive c. Rectangular d. Stationary

A population policy aimed at achieving zero population growth is most effective in a country with a constrictive population pyramid. This type of pyramid indicates a lower number of young individuals compared to older populations, signaling that the country is already facing challenges related to declining birth rates. Implementing policies that encourage family planning and support for aging populations can aid in stabilizing this demographic trend. On the other hand, a stationary population pyramid reflects a balance between birth and death rates, implying that the population is neither growing nor shrinking significantly. In such a scenario, zero population growth policies may not be as vital, since the demographic balance is already relatively stable, making it easier for governments to monitor and adapt to changing needs without drastic interventions.
