Urbanization refers to the process of population migration from rural areas to urban areas, resulting in the growth and expansion of cities. Megacities, on the other hand, are cities with a population of over 10 million people. The process of urbanization has a significant impact on economic inequality within megacities, both positively and negatively.
One of the main ways urbanization affects economic inequality in megacities is through the concentration of wealth and resources. As more people migrate to cities in search of better job opportunities and improved living standards, the demand for housing, infrastructure, and services increases. This leads to the development of high-income neighborhoods and commercial areas, where the wealthy and privileged reside. These areas often have better access to quality education, healthcare, and other essential services, creating a significant disparity between the rich and the poor.
Additionally, urbanization can also lead to the creation of informal settlements or slums within megacities. As the influx of migrants exceeds the capacity of the formal housing sector, many individuals and families are forced to live in substandard and overcrowded conditions. These informal settlements lack basic amenities such as clean water, sanitation, and electricity, further exacerbating economic inequality. The residents of these slums often face limited access to education, healthcare, and formal employment opportunities, trapping them in a cycle of poverty.
Furthermore, urbanization can also contribute to the widening income gap by increasing the cost of living in megacities.
