Final answer:
The term 'Global South' refers to the lesser developed nations, mainly in the Southern Hemisphere. The cities in these countries are growing rapidly and house a significant share of the world's urban population. Precise figures require specific data, but the trend shows dense urbanization in the Global South.
Step-by-step explanation:
The term 'Global South' refers to the less economically developed countries, predominantly located in the Southern Hemisphere. Considering current demographic trends, it can be inferred that a significant proportion of the world's urban population resides in Global South cities. However, without a specific figure provided in the question or access to the most recent data, a precise answer cannot be given. It's important to note, though, that urban populations in cities of the Global South have been increasing over the years. This is a reflection of global urbanization trends where previously rural populations move to urbanized areas in search of better opportunities and services.
A closer look at urbanization reveals that different regions of the world have varying levels of urban populations. For example, North America has an urban population of approximately 82%, whereas Africa has just 40%. The trajectory of urbanization suggests that more people are dwelling in urban areas, with cities in the Global South becoming some of the most densely populated. This growth is part of the reason the most densely populated cities are found in the Global South, as opposed to several decades ago when the biggest cities were largely in the Global North. Cities like Tokyo and New Delhi, while not in the poorest nations, are indicative of this shift; they are among the largest in terms of population density.
