Understanding Urbanization in South America: Key Insights from Population Data

South America is one of the most urbanized regions in the world, with about 80% of its population living in cities. This rapid urban growth brings both challenges and opportunities. On one hand, cities must deal with issues like overcrowding, inequality, and environmental stress. On the other, urbanization can drive economic growth, innovation, and sustainable development.

This data challenge focuses on historical and current population trends to uncover urbanization patterns and demographic shifts. The goal is to identify insights that can help improve urban planning, promote sustainable growth, and build resilient cities.

To better understand South America's urbanization, this challenge foces on six key indicators:

1. Population Growth (Annual %): Measures how quickly the total population is growing each year. A high growth rate can signal economic opportunities but also strain on resources.

2. Urban Population (% of Total Population): Shows the share of people living in cities compared to rural areas. This helps track the extent of urbanization.

3. Urban Population (Absolute Numbers): Examines the total number of people living in urban areas, providing a sense of scale.

4. Urban Population Growth (Annual %): Tracks how fast cities are expanding. A rising rate may indicate migration trends, housing demand, or economic shifts.

5. Total Population: Provides a baseline to compare other indicators and assess overall demographic trends.

6. Population in Urban Agglomerations of More Than 1 Million (% of Total Population): Looks at how many people live in large urban centers with over one million residents. This highlights the concentration of people in major cities.

Understanding these trends can help policymakers, businesses, and communities plan for the future. By analyzing data, we can find ways to make cities more inclusive, efficient, and sustainable.
