20 Countries with Most Cities Over 1 Million

In this piece, we are going to look at 20 Countries with Most Cities Over 1 Million. If you want to skip our detailed analysis on the population dynamics of the world, and how declining birth rates are changing those dynamics, you can go directly to 5 Countries with Most Cities Over 1 Million.

Although the world population sits healthy at 8 billion mark as of 2024, the global demographic landscape is undergoing a transformative shift, with declining birth rates playing a pivotal role in the discussion on overpopulation, especially in countries with numerous cities surpassing one million inhabitants.

Over the past 70 years, countries worldwide have experienced a remarkable decrease in birth rates, which mirrors evolving societal norms and economic progress. Notably, nations like China and South Korea have witnessed a substantial decline in birth rates, dropping by over 80% since 1950. While declining birth rates signify advancement in socio-economic development and a shift towards prioritizing education and career over starting families, they also introduce challenges associated with an aging population and potential labor shortages.

The balance between low birth rates and overpopulation in cities presents complex scenarios, necessitating thoughtful urban planning and sustainable development strategies to address the strain on resources and social services. As the global fertility rate has declined significantly over the past five decades to 2.3, falling below the critical replacement level of 2.1, the implications of this demographic shift on overpopulation are increasingly pertinent.

The need for proactive measures to navigate the consequences of declining birth rates is crucial, ensuring a balanced approach to population dynamics, sustainable urban growth, and inclusive societal development. In the United States, the downward trend in birth rates has been notable, with a nearly 23% decrease since the Great Recession, highlighting the need for understanding the implications of this demographic transformation. Immediate attention and strategic interventions are essential to address the challenges posed by declining birth rates and to create a balanced equilibrium between low birth rates and the potential impacts of overpopulation.

Various industries, including agriculture, manufacturing, construction, retail, and services, have strong ties to densely populated countries. These sectors rely on factors like labor availability, access to resources, market demand, and robust infrastructure that are typically abundant in highly populated regions.
