What is the Purpose of a High-Resolution Population Map? Nutritional Density: This is the ratio of a state's total population to the area under food crop cultivation in that state. Economic or Numerical Density: To calculate a state's economic density, divide the weighted index of its population by the production capacity index of all its financial resources as a percentage.ĥ. Farmers, agricultural laborers, and their families are part of the agricultural population.Ĥ. Agricultural Density: A state's agricultural density is the ratio of its total rural population to its agricultural land. It is also known as the human-to-agricultural land ratio.ģ. Functional Density: Functional density is a region's population ratio to agricultural land. It is stated as a percentage of the total population divided by the entire area.Ģ. Density arithmetic: Arithmetical Density is the number of people living in a square kilometer region. The following are the several forms of population density:ġ. Population density is represented as an area and its associated conditions. Specifically, people tend to congregate more frequently in urban areas, while people living in rural areas are typically distributed more sparsely over the same land area. However, populations are dispersed unevenly throughout regions. This figure presents an average of how many people would live inside one square mile if the United States population was evenly distributed across all of its land areas. The overall US population density is estimated by dividing the US population by the entire land area in the US (approximately 3.5 million square miles). Population density is commonly expressed in the United States as the number of people per square mile of land area. Population density is a comparison of the intensity of people across geographic areas (i.e., neighborhoods). Even within cities, population densities vary significantly from one neighborhood to the next. While the population density in the United States is roughly 90 people per square mile, most people reside in cities with a substantially greater density.
