Human populations have moved and settled in a variety of locations over a long period of time. But remember that population density is only one part of the study of geographic patterns and characteristics of human population. [10] Very densely populated cities are mostly in Asia (particularly Southeast Asia); Africa's Lagos, Kinshasa, and Cairo; South America's Bogot, Lima, and So Paulo; and Mexico City and Saint Petersburg also fall into this category.[11]. Arithmetic population density calculations explain the idea of how crowded a specific area is. Departments of Energy and Agriculture all use population data from the As a member, you'll also get unlimited access to over 84,000 Today we're going to take a look at this concept of population density. Even if there is enough food available in the supermarket (and in the US, there always is), people might not be able to afford it, or they might not be able to get to the supermarket, or they might be only able to afford food with insufficient nutritional value, or any combination of these. For example, the World Health Organization, the U.S. Energy Information Administration, the U.S. This measure of population density is also called crude density. Density is the number of things - people, animals, buildings, insects, even scientific matter, in a particular area. 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. Growing populations use large amounts of nonrenewable resources like timber, coal, and oil. Much of the Egyptian population works in agriculture. Line Bar Map. mi.). Global Change Research Program, and the U.S. Food and Agriculture Organization and World Bank population estimates. 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. Global Change Research Program, and the U.S. In this explanation, we look at agricultural population density, which is one way to understand the above questions. In general, they must have a core with a population density of 1,000 persons per square mile and may contain adjoining territory with at least 500 persons per square mile. Examples include the population density of France, which is Frances population divided by the square number of kilometers, which is approximately 109.8 people per square kilometer. The US has around 609,000 mi2 of arable land (you may see figures ranging from 300,000 to 1,400,000, which reflects different definitions of "arable land" to include grazing land, and whether only land productive in a given year is measured). With arithmetic density under our belts, let's take a look at physiological density. However, some cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace. Then, divide the number of farms by the arable land area. We also outlined how population density can affect the environment, and discussed the future of areas that may be in decline because of overpopulation. The table below compares the agricultural population density of Florida and Texas. You will find a lower level of agricultural density in more developed countries, because they have access to better technology and money, which allows an individual to work more farmland. [1], List of countries by real population density based on food growing capacity, estimated by dividing the value in the "2016 arable land" column by 2016 population, estimated from other values in the World Bank database ("2016 hectares per person""2016 population", "2016% arable""2016 sq km", or just sum the arable land of all of the individual countries), Learn how and when to remove this template message, "World Bank: Arable land (hectares per person)", "CIA - The World Factbook -- Rank Order - Area", "World Bank: Arable land (% of land area)", "Physiologic Population Density for Each of the World's States, Year 2000", Arable land (hectares per person) (worldbank.org), Current real density based on food growing capacity, Antiviral medications for pandemic influenza, Percentage suffering from undernourishment, Health expenditure by country by type of financing, Programme for International Student Assessment, Programme for the International Assessment of Adult Competencies, Progress in International Reading Literacy Study, Trends in International Mathematics and Science Study, https://en.wikipedia.org/w/index.php?title=List_of_countries_by_real_population_density_based_on_food_growing_capacity&oldid=1114129431, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License 3.0, This page was last edited on 4 October 2022, at 23:51.

Clearly, the country will be Outlying counties that are economically tied to the core counties as measured by labor-force commuting. The population density calculation measures how many people live in an area. This measure of density is useful, because it can give us a rough estimate of how many people an area of farmland can reasonably support. Global Change Research Program, and the U.S. Departments of Energy and Agriculture all use population data from the [citation needed]. Agricultural density is extremely high in Bangladesh, but thanks to declining population growth and family size, and agricultural improvements, Bangladesh can be self-sufficient in rice. succeed. Welcome to the world of agricultural statistics! Be perfectly prepared on time with an individual plan. It is key to understand that population density also affects the need for infrastructure and urban services. What does all this mean? A lock ( There are large areas of Florida that are not heavily populated, with a lot of green space. A complete enumeration of a population. Agricultural population density is the ratio of farms (or farming population) to arable land. Texas does have large cities such as the Dallas/Fort Worth Metroplex, Houston, Austin, and San Antonio, but there are vast areas of west Texas that are largely vacant. It is important to know and be able to apply the concepts of population density, at every scale from local to global. Researchers and policymakers share the task of choosing appropriately from among alternate rural definitions currently available or creating their own unique definitions. The United States, with 4.11 million square kilometers of arable land, has an agricultural population density of about 1.5 farmers per square kilometer. Label. Egypt, with 36,350 square kilometers of arable land has an agricultural population density of 864 farmers per sq. An error occurred trying to load this video.

Population (July 2017 est.) [8], Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Technology and machinery allow less people to farm more land and produce more food. While Florida does have fertile farmland, it's a densely populated state with a lot of water that doesn't support food production. Population living in areas where elevation is below 5 meters (% of total population) Urban population living in areas where elevation is below 5 meters (% of total population) The US has around 2 million farms, decreasing every year (in 2007, there were 2.7 million farms). Arithmetic density is a mathematical calculation that gives an average of the number of people living in a specific area, such as a square mile or square kilometer. Create your account. A country such as Greenland has a very low carrying capacity. Productivity can change from place to place and year to year for the same crop. Fewer farmers, less food? What can we deduce from looking at a countrys physiological density? Arithmetic population density is a calculation of the total number of people divided by the total area of a place, also called real density. Florida has a total population of 19,378,102 and the total area of the state is 47,126.40 people. Greenhouses on farmland at the edge of a city.

Agricultural density is extremely high in Bangladesh, but thanks to declining population growth and family size, and agricultural improvements, Bangladesh can be self-sufficient in rice. Well, a single adult needs at least 300 pounds of food per year (children need less, with the amount varying by age), much of which can be provided by a staple, carbohydrate-rich crop like rice. Low agricultural density is also a sign that large farms using mechanized farming methods are common. You will need to know the differences for the AP Human Geography exam. 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 Create beautiful notes faster than ever before. Natural Increase Rate & Formula | What is Natural Increase Rate in Populations? The productivity of the land is also a factor in studying the physiological density of an area. The simple definition of population density is the number of persons per unit of land area. Food and Agriculture Organization and World Bank population estimates. Agricultural population density is a measurement of the average number of farms on arable land in an area. Even if they sell it, the food may be destroyed down the line rather than sold if it is not making a profit (restriction of supply can raise profits). To find the agricultural density, divide the area of farmland by the population of farmers in that area, giving you an average of land worked by each farmer. When this food becomes too expensive, and such places can't fall back on domestic production, people may go hungry as a result. Her diverse expertise includes Science, Nutrition, Culinary Arts, Business Management, and Human Growth and Development. Population is an important topic in AP Human Geography and is heavily tested on the exam. Arithmetic population density does not take into account any of the characteristics or quality of the land in the area. ft) per person (cf. Agricultural density is a statistical measure of population density. ''Arable'' land is another term for farmland suitable for producing food. Together with density, carrying capacity can define whether an area is overcrowded. This is often expressed in hectares or acres: 65 acres or 26 hectares per farm in this case (a square mile has 640 acres and there are 0.4 hectares in an acre). The study of population is important to anyone who is going to take the AP Human Geography Exam. km of land area) - South Africa.

This is a sign that, compared to the US, the effort to produce food on their arable land is very great. High agricultural population density numbers show that it takes many farmers to produce food on the available land. mi.). The total number of people is divided by, for example, one kilometer, to determine the average density on that acre. The area below the kernel density for the agricultural sector is equal to 0.45, showing that 45% of the world population relies on agriculture for its livelihood. Examples of the causes of reduced fertility in low population densities are [2]. It's a sign that perhaps they are using old fashioned methods to grow crops and could improve yield with modernization. A regional-economic concept underlies the formation of the metropolitan-nonmetropolitan classification. The darkest red areas have a population density of 600 or more people per square kilometer. International Migration Trends & Causes | What is International Migration? You can have an area of high population density but is not considered overcrowded if the area has a high carrying capacity.
