agricultural population density

Let's focus on rice, Bangladesh's staple crop, planted on 3/4 of the country's arable land. Global Change Research Program, and the U.S. [5][6] In fact, 95% of the world's population is concentrated on just 10% of the world's land. In this AP Human Geography study guide, we will explore the concept of population density as a sub-set of demography, which is the study of the characteristics of a human population. Compare and contrast arithmetic and physiological population density. Population density is a measurement of the number of people in an area relative to its size. License : CC BY-4.0. What is the purpose of agricultural density? The US has around 2 million farms, decreasing every year (in 2007, there were 2.7 million farms). Agricultural density measures the number of farmers specifically on each unit of The productivity of the land is also a factor in studying the physiological density of an area. Last we come to agricultural density. Stated rather simply, population density is a measurement of the number of people in an area relative to its size. Total Population Total Area of Farmland = Physiological Population Density The calculation helps determine how many people depend on an area of land for food. Let's continue with the example of Country A, above, where the average farm is 65 acres. Agricultural and physiological density calculations provide a more complete picture of what the area is like. Its recent agricultural census measured 82,988 farms of all different sizes. The country is dominated by the delta of the Ganges/Brahmaputra which has some of the world's most fertile soils. Outlying counties that are economically tied to the core counties as measured by labor-force commuting. Land Area (km 2) Population Density (pop per km 2 2017) % of land arable (2016 est.) An average adult needs to consume about _______ pounds of food per year. Students will be able to calculate arithmetic (population), agricultural, and physiological densities at the state and national levels. A higher level of agricultural density suggests that available arable land is being used by more farmers and may reach the limit of its production potential sooner than where agricultural density is lower. Agricultural density measures the number of farmers specifically on each unit of Country A's arable land is 8,429 square miles (26,341 * 0.32) so its agricultural density is 9.85 farms per square mile. Arable land is land that is suitable for producing food. The AP Human Geography exam will test your knowledge of human population characteristics and the how population density is used to explain the relationship between people and the environment. Which types of countries have a lower agricultural population density? Let's say the farm is owned by a family of three. Total Population Total Area of Farmland = Physiological Population Density. Agricultural density is found by dividing an area of farmland by the total population of farmers in the same area. To unlock this lesson you must be a Study.com Member. 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. I like to think of it as just being simple arithmetic. Population density data can be important for many related studies, including studies of ecosystems and improvements to human health and infrastructure. Make sure to check out our guides on other aspects, too. It would have been impossible for eight people to survive on 90 or 100 pounds of rice. Small population size typically characterizes a rural place, but how small is rural? 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. Growing populations use large amounts of nonrenewable resources like timber, coal, and oil. 19,378,102 47,126.4 = 411.2 people per square mile. Researchers and policymakers share the task of choosing appropriately from among alternate rural definitions currently available or creating their own unique definitions. In general, increases in population density equate to problems for a country. One might expect that since Texas is bigger in size. However, the US also has malnutrition and hunger. StudySmarter has explanations on all three that include a variety of useful comparisons to help you keep them straight. What does all this mean? There are large areas of Florida that are not heavily populated, with a lot of green space. mi.). Role of Demographic Rates & Population Distribution on Population Health, Sequent Occupance, Acculturation & Assimilation: Definition & Examples. This is a sign that, compared to the US, the effort to produce food on their arable land is very great. It provides an average of how many people live in a specific area, such as a square mile or kilometer. Agricultural population density tells us the average farm size and whether there are enough farms to feed the population. 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. The measure of population density refers to the number of people living in rural areas per unit of agricultural land. However, if only the Earth's land area of 150,000,000km2 (58,000,000 sq. The simple definition of population density is the number of persons per unit of land area. Population density is population divided by total land area, sometimes including seas and oceans, as appropriate. Max Planck Institute of Demographic Research: What Is Demography? If a media asset is downloadable, a download button appears in the corner of the media viewer. Scientists have even studied how happiness correlates with population density. To calculate physiological population density, divide the total population by area of farmland. The ability of the farmland to produce food will be used up more quickly in areas of high physiological density. They may or may not contain any individual cities of 50,000 or more. Identify your study strength and weaknesses. Population density data can be used to quantify demographic information and to assess relationships with ecosystems, human health, and infrastructure. Agricultural density is a useful statistic for recognizing trends in population growth, development, and stability. Central counties with one or more urbanized areas; urbanized areas (described in the next section) are densely-settled urban entities with 50,000 or more people. Welcome to the world of agricultural statistics! Agricultural density is a statistical measure of population density. km of land area) Food and Agriculture Organization and World Bank population estimates. Total # of farms Total Area of Farmland = Total Agricultural Population Density. Now, let's assume that around half an acre is necessary to feed a single person per year. 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 It helps planners determine how long the land will be able to produce food to feed the population. When this food becomes too expensive, and such places can't fall back on domestic production, people may go hungry as a result. The overall population of a country is often rising. Typically, countries in the developed world have the lowest agricultural population density. Ap Human Geography : Example Not necessarily. Farms may grow food exclusively for export earnings. That's the minimum number of people who need to be fed by a square mile of land if the country is to be self-sufficient in food. With the farm only needing to feed three people (the farming family), the rest can be sold and go to feed 127 more people. This map is a valuable comparison tool, but it doesn't tell the whole story of the area. This is a list of countries ordered by physiological density. Food and Agriculture Organization and World Bank population estimates. The amount of land needed to feed a person varies based on the quality of the land (e.g., soil), type of crops grown, access to nutrients, access to fertilizers, and other factors. The total number of people is divided by, for example, one kilometer, to determine the average density on that acre. Martin's AP Human Geography: Population Density 7. I feel like its a lifeline. In terms of household size, farm families topped eight in the early 1970s, and are now half that. The simple definition of population density is the number of persons per unit of land area. The calculation is similar to other population density formulas, except the number of farms is used in place of people. 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. A 65-acre farm can feed 130 people, and a square mile, or around ten farms in Country A, can feed almost 1,300 people. Once these natural resources are gone, they are gone forever. Ethnic Competition, Division & Domination, Causes of Death, Determinants of Mortality & Mortality Rates, Epidemiological Transition Model | Stages & Examples. More developed countries usually have lower agricultural density than less developed countries. Official websites use .gov Arithmetic Population Density. To put this concept into numbers, the United States has a physiological density of 179, whereas Djibouti, in the Middle East, comes in at 131,101. [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. The calculation helps determine how many people depend on an area of land for food. Then, divide the number of farms by the arable land area. Urbanized areas have been delineated using the same basic threshold (50,000 population) for each decennial census since 1950, but procedures for delineating the urban fringe are more Population density (people per sq. Agricultural density is found by dividing an area of farmland by the total population of farmers in the same area. Agricultural population density is useful to compare how labor-intensive farming is in a given area. The trend is that small farms must get bigger, or be bought out. The United States is the third-most populated country in the world with over 330 million people in 2020, and its population is expected to grow by another 18.5 million in just the next ten years. 3 - Cornfields in Iowa. Florida has relatively little land suitable for producing food compared to Texas. Many people associate Florida as great for growing crops. Arithmetic population density is a calculation of the total number of people divided by the total area of a place, also called real density. Population density can have a negative impact on our environment and natural resources. 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. 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. Counties are the standard building block for publishing economic data and for conducting research to track and explain regional population and economic trends. Why do populations move to a new location? You may also confuse. Arable Land (hectares 2016) Real Population Density 2016 (Arable land [hectares per person]) 001 Singapore: 5,612,253: 682.7: 7,916: 0.79%: 560: 0.0001 - Hong Kong: 7,391,700: 1,042: 7,040: 2.86%: 3,000: 0.0004 002 Bahrain: 1,492,584: 665: 1,936: 2.06%: 1,600: 0.001 Singapore has the highest agricultural density of any country in the world. Label. Maybe, maybe not. It is useful to compare agricultural density and physiological density, as both are related to the amount of arable land available. Albert.io lets you customize your learning experience to target practice where you need the most help. Upload unlimited documents and save them online. Alison Topper has instructed adult and school age learners for over 16 years, in public schools and community education settings. 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. Epidemiology: how densely populated areas differ with respect to incidence, prevalence, and transmission of infectious disease. 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. Test your knowledge with gamified quizzes. That movement or migration raises several questions. 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 main factors have been the weather and the changing climate, the struggle to reduce population growth in a socially conservative country, exposure to toxic agricultural chemicals, and a range of political and economic issues. When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. All remaining counties, often labeled "noncore" counties because they are not part of "core-based" metro or micro areas. 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.
