väestöntiheyden

Väestöntiheys, or population density, is a measure of population per unit area. It is a statistical measure that indicates how crowded a region is. The most common unit of area used is the square kilometer or square mile. To calculate population density, one divides the total population of a region by its total land area. For example, if a city has 100,000 people and covers 50 square kilometers, its population density would be 2,000 people per square kilometer.

Population density varies greatly across the globe. Densely populated areas are often found in urban centers, coastal regions, and fertile river valleys. Conversely, sparsely populated areas are typically found in deserts, polar regions, mountainous terrains, and vast forests. High population density can present challenges such as strain on resources, infrastructure, and housing, but can also foster economic activity and innovation. Low population density can sometimes lead to challenges in providing services and maintaining infrastructure over large areas. Understanding population density is crucial for urban planning, resource management, and comprehending demographic trends.
