The critical effects of a runaway population growth on a country’s national development, both for developed and developing countries, have been widely researched and debated by many, both on the academic and practical levels. Proof of that is the utmost importance to efficiently sustain a managed population growth rate of a developing country. The Philippines is no exception. As a developing country, it cannot afford to continue on its ambivalent stand on this matter. Other neighboring countries, like Japan and China, have legislated and implemented successfully measures to curtail their own population growth rates. In a predominantly Catholic country like the Philippines, however, any form of direct legislation to curtail population growth would certainly meet stiff resistance and probably be considered downright unacceptable. What then can our country do to properly manage the population growth issue? This paper aims to present an alternative solution to the said problem. The proposed development theory herein presented centers on early and continuous integration in the formal educational system’s curricula of the values of a properly timed marriage, or childbirth, and the optimal family size preference by citizens in the context of nationalism. Institutionalizing these values-inputs as the preferred and acceptable social behavior in the formal education system is virtually a form of “legal indoctrination.” The paper challenges the philosophy and approach of how population education (POPEd) is carried out in this country, which is sad to say, has been ineffective as gleaned from the data and statistics gathered in this study.
