populácii

Populácia refers to the total number of inhabitants in a specific geographical area, such as a city, region, country, or even the entire planet. It encompasses all individuals of the same species residing in that area at a given time. The study of populations, known as demography, examines various characteristics like size, density, distribution, birth rates, death rates, and migration patterns. These factors influence a population's growth, decline, or stability.

Population dynamics are shaped by several key elements. Birth rate, the number of live births per 1,000 people in a year, contributes to population increase. Conversely, the death rate, the number of deaths per 1,000 people in a year, leads to a decrease. Migration, the movement of people into (immigration) or out of (emigration) an area, also significantly impacts population size.

Understanding population trends is crucial for various fields, including urban planning, resource management, public health, and economic development. For instance, a rapidly growing population may strain resources like water, housing, and food, while an aging population might require more healthcare services and pose challenges to the workforce. Analyzing population data helps policymakers make informed decisions to address societal needs and plan for the future.
