Examples of the causes of reduced fertility in low population densities are [2]. The physiological density formula used to calculate physiological density uses total area of farmland instead of total area like arithmetic density. But the biggest factor is economies of scale: it is getting harder and harder for smaller farms to compete with larger farms, as costs of machinery, fuel, and other inputs go up.

Texas is much less densely populated and has a large amount of land that does support food production, including large areas that support cattle for beef. Population density of microorganisms is often more than 1000 times higher in the cultivation beds than in the room air because the microorganisms are fed by dead and alive roots, algae, and other organic substances in the cultivation beds (algae grow photosynthetically only under the presence of light, water, and nutrients). There are positive and negative influences of population density on political, economic and social processes. [1], Low densities may cause an extinction vortex and further reduce fertility. Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources With this massive amount of people, New York City is a great example of a place with a very high population density.

The number of individuals living within that specific location determines the population density, or the number of individuals divided by the size of the area.Population density can be used to describe the location, growth, and migration of many organisms. Researchers and policymakers share the task of choosing appropriately from among alternate rural definitions currently available or creating their own unique definitions. Population Distribution Overview & Factors | What Affects Population Distribution? These different methods are used to explain the relationship between people and the environment, so that geographers can understand the impact that population has on their quality of life, the services that governments can provide them, and the impact that humans have on our planets resources. That movement or migration raises several questions. The areas on the map in yellow have very low population density - between 0 - 49 people per square kilometer. 19,378,102 47,126.4 = 411.2 people per square mile.
