introduction

In this current of modernity, population growth is at the intersection of some of today's most pressing challenges. This is the case when the global population increases the pressure on local resources, which can worsen the current situation. The interaction between demographic development and local population decline is the cause of increasing concern, especially when our planet is already struggling with various implications (Kara Anderson, 2023). As such, population growth is one of the important topics discussed, where for most of human history, the global population was a fraction of what it is today. Over the past few centuries, the human population has undergone remarkable changes, but after a period of very rapid population growth, demographers expect the world's population to stabilize shortly. For example, this chart data shows changes in population development occurring in Malaysia, including changes in population growth, including the way the population is growing around the world, which brings changes and things, or preliminary plans expected by demographers for the future (Hannah Ritchie et al., 2025). As a result, population growth refers to the change in the number of individuals living in a certain region in a certain period. This change can be caused by the difference between the birth rate and the death rate, migration and emigration. In general, when the number of births exceeds the number of deaths, or when more people move into a region than those who leave it, positive population growth occurs. Conversely, negative population growth occurs when deaths exceed the number of births or when more individuals leave a region than enter it (Kara Anderson, 2023).

In the meantime, population refers to all the people living in a certain country, area, or place (Choo Chin Low, 2019). This is so, leading to a perspective that ranges in scale from a small village to a large country or even the whole world. Because of this, population dynamics is a serious issue facing the world today, especially in urban centers. For example, according to the United Nations (2018) more than 55% of the world's population currently lives in urban areas, and this figure is expected to increase to 68% by 2050 (United Nations, 2018). As a result, the world's rapid urbanization has put enormous pressure on housing, infrastructure and public services. At the same time, there are many cities around the world where there is an unbalanced development heritage area due to population growth that has caused gentrification and loss of local identity. In a formula, this population problem becomes a change to the increase and decrease of the local population that will affect the social structure and cultural continuity of the community in the area, especially in cities that have deep historical significance.Furthermore, the thing that can be linked in the global population problem is through the study area carried out in the central area of ​​Georgetown called Komtar where previously there was a period of population decline, but according to the data of the last few years shows that the population in the city is increasing but not the original residents who are settled (PRB, 2024). However, population growth in this area is not entirely beneficial as population growth here has the biggest impact. For example, the increase in population density, especially foreigners in this area, has put pressure on the infrastructure and there has been an increase in the cost of living and exacerbated issues such as traffic congestion and environmental degradation (United Nations, 2024). Finally, the population growth caused by tourism, because this area is a tourist attraction, leads to the conversion of residential spaces into places of business and administrative affairs, thus disrupting the lives of citizens and reducing the supply of housing for the local population (SDG for Malaysian States, 2024). Therefore, this will result in gentrification, making it difficult for residents to continue living in their original area.

    In this context, when there is a significant population change and migration in one country to another there is a strategy taken by the United Nations at the UN Population Division which gathers information on issues such as international migration and development, urbanization, world population prospects and policies, as well as marriage and fertility statistics has supported the Commission on Population and Development to implement the Program of Action adopted by the International Conference on Population and Development (IPCD) 1994 where it has prepared the official demographic estimates and projections of the United Nations for all countries and regions in world to help States build capacity to enact population policies, and improve the coordination of related UN system activities through its participation in the Committee for the Coordination of Statistical Activities (United Nations, 2024). For example, the population growth in Komtar, Georgetown has an impact on the cultural attractions and the surrounding area (Lim Sok Swan et al., 2017). This is because as the area becomes more commercially attractive, traditional businesses, small businesses and community institutions may be replaced by chain stores and tourist enterprises being a positive change but actually weakening the cultural authenticity of the area and diminishing the historical character that makes Georgetown a World Heritage. At once, the increase in population or new visitors may really reduce the spirit of the original community in the area

In this situation, to deal with this population problem, a balanced urban planning approach should be implemented through a systematic plan to support the development of the city and preserve the city's heritage. For example, properly regulating housing development, encouraging community economic activity, and ensuring that the voice of local residents is heard in the decision-making process. Clearly, urban theorists recommend the use of frameworks such as "inclusive urbanism" and "culturally sensitive planning" to ensure that development improves community conditions rather than replacing them (SDG for Malaysian States, 2024). In doing so, the urban planning framework is essential in heritage cities where the identity of the cities and the local quality of life are preserved and balanced. Hence, through the study in Komtar, Georgetown Penang was focused and explored how the changing population problem affects the heritage zone of this city as a key area in the World Heritage Site of Georgetown, Komtar which reflects both the challenges and opportunities of urban development in the context of heritage. By examining the pros and cons of urban population change, this study aims to provide a deeper understanding of sustainable urban population management in heritage zones.
