Analysis

The bar chart of 2025 population clearly shows that Tokyo and Delhi are the largest megacities, while smaller cities like Istanbul have far lower populations, highlighting the huge scale differences among the top 15 cities. The dot plot of population change percentages emphasizes trends in growth, showing that cities in Africa and South Asia, such as Kinshasa and Lagos, are expanding rapidly, while cities like Tokyo and Osaka are slightly shrinking. The pie chart represents each city’s share of the total combined population, revealing that a small number of cities dominate the global urban population. Together, these visualizations provide both absolute and relative perspectives on population size and growth trends, helping identify which cities are major hubs and which are rapidly emerging.

These insights are useful for urban planners, policymakers, businesses, and international organizations. Knowing which cities are growing fastest can guide infrastructure investments, transportation planning, and resource allocation to accommodate expanding populations. Understanding the concentration of global urban populations, as shown in the pie chart, helps governments and NGOs prioritize services like healthcare, education, and housing where they will have the greatest impact. Businesses can also use this data to target markets in rapidly growing cities, while environmental planners can anticipate and manage the challenges of urban expansion, such as pollution and energy demand. Overall, combining population size and growth trends provides actionable knowledge for real-world decision-making.
