A geographer maps the population density of two towns. Town X covers 120 km² and has 48,000 residents. Town Y covers 180 km² with 72,000 residents. What is the difference in population density (per km²) between the two towns?
["Understanding Population Density: A Geographer’s Perspective with Town X and Town Y", "When analyzing human settlements, geographers rely on population density as a key metric to understand how many people live within a given area. Population density measures the number of residents per unit of land, typically expressed as people per square kilometer (or per square mile). This concept helps compare urban and rural areas, plan infrastructure, and guide sustainable development.", "In this example, two towns—Town X and Town Y—offer a clear illustration of population density differences through straightforward calculation.", "Town X: A Compact Community\nTown X spans 120 square kilometers and is home to 48,000 people. To calculate its population density:\n[\n\ ext{Population Density (Town X)} = \frac{48,000 \ ext{ residents}}{120 \ ext{ km}^2} = 400 \ ext{ residents per km}^2\n]", "Town Y: A Spread-Out Settlement\nTown Y covers a larger area of 180 km² and supports 72,000 residents. Its population density is:\n[\n\ ext{Population Density (Town Y)} = \frac{72,000 \ ext{ residents}}{180 \ ext{ km}^2} = 400 \ ext{ residents per km}^2\n]", "Comparing the Two Towns\nSurprisingly, despite differences in size, both Town X and Town Y have identical population densities: 400 people per square kilometer. This means Town X, though smaller, packs a comparable resident concentration when measured by area, whereas Town Y stretches its population across more land.", "Why This Matters\nGeographers use such comparisons to reveal insights about urban planning, housing demand, transportation needs, and resource allocation. Even with different land footprints, the balance of population distribution shapes each town’s unique challenges and opportunities.", "In summary, while Town X’s compactness yields efficient land use, Town Y’s broader footprint reflects a more dispersed community. The consistent density underscores how geography influences density more than mere size—proving that population pressure isn’t always tied to area alone.", "Understanding population density through precise measurement enables smarter decisions in regional development, ensuring communities grow sustainably, regardless of their geographic scale.", "---", "Follow this guide to explore how population density impacts urban planning, environmental sustainability, and social services across different settlements."]
