This IA was about “How does the working-age population increase over time? What is the particular trend?”. I used logistic growth model for my essay.

No one would hesitate to admit the aging issue as one of the biggest challenges that South Korea is facing recently.

The Korean Working Age Population and the Logistic Growth Model

Introduction

No one would hesitate to admit the aging issue as one of the biggest challenges that South Korea is facing recently. Because the aging population is strongly correlated with economic, societal, and health-related problems, the issue has not been ignorable among South Korean residents, including myself. Indeed, I have witnessed the increased numbers of media coverage talking about low fertility rates and possibility of declining population growth. According to the population forecast model, although the population growth has been increasing at a steady rate for the past decades after the end of Korean War, it estimates that the population will decrease after 2027.1 With my growing interest in the prospect of South Korea, I wanted to discover the general trend of the aging population’s effect on Korea’s economy. Upon research, I found out that the working-age population is the best indicator that reflects the impact of low fertility rate on the potential labor workforce. According to Investopedia, the working-age population is the total population of the working age that is considered willing and able to work in a country, which provides an estimate of the potential workers in an economy. I was able to connect this information with what I learned in economics, in particular macroeconomics, as increase in the working population results in economic growth or increase in real GDP. Moreover, the working-age population is significant in an economy as it is the group that can financially support the aging population. Therefore, my research question is: How does the working-age population increase over time? What is the particular trend? (How does it differ from the OECD’s total working-population graph?) In order to answer these research questions, I will model the working-population graph that I found on the “OECD Data” website to discover a particular trend of Korea’s working-age population growth (and further compare it with OECD graph).

The ultimate goal of this investigation is to connect everyday life knowledge with the one that I had learned mainly in mathematics, but also in economics as well. In order to devise a mathematical model that fits the pattern of change, I will be using software Logger pro and Desmos Graphing Calculator. Throughout this investigation, I want to see the connection between concepts of mathematics and real-life application around us. I feel that this investigation has great significance as I can use the information to analyze and predict the future economic path that South Korea should take…
