Greece: High Resolution Population Density Maps + Demographic Estimates. Of course, its important to remember that the population density is an average, not a direct relation. reason behind it is technology. This AP Human Geography study guide aims to help you understand what you might need to know when you take the AP exam. Its not because that the farmers of, are more energetic or smarter but because they have more. Fig. Fig. Disclaimer, National Library of Medicine Physiological population density is viewed as a superior measure of population density for what reason? Biomed Eng Online. 3 - The prickly pear or nopal is one of many species of cacti that grow as weeds in Mexico and elsewhere but are also farmed for their delicious fruit. The difference between the two makes a big difference! Water becomes scarcer and scarcer. In our example, if 100,000 more people moved to the same area, we would end up with a physiological density of 27.5 people per square kilometer and as the numbers continue to go up and up we start to consider whether theres really enough food for everyone. 2015;26(1):e1-7. This eclectic list is 1) Singapore, 2) Bahrain, 3) Seychelles, 4) Kuwait, 5) Djibouti, 6) United Arab Emirates, 7) Qatar, 8) Maldives, 9) Andorra, and 10) Brunei. High population density? A higher physiological density suggests that the available agricultural land is Best study tips and tricks for your exams.

On your AP Human Geo exam, you may be asked to consider different types of population density. Well give you challenging practice questions to help you achieve mastery in AP Human Geography. Fig. The calibrated approach will narrow the gap between length-scale dependent measurements, and will permit spatiotemporal quantitative and reliable detection of pathologies. Traditionally, arable land has meant rural land where plants grow in soil. 4.6 (5 reviews) Term. WebThere is arithmetic density, physiological density, and agricultural density. A net food importer because of its high physiological population density. Country X might not be self-sufficient in food, then. A systematic approach to propose a standardization protocol for CT imaging in vivo included: 1) estimation of pathologic MD ranges by performing a comparative meta-analysis on 2009-2019 data from the PubMed database; 2) calibration of cone-beam CT (CBCT) and micro-CT scanners with phantoms of known mineral densities (0, 250, 500, 750 and 3000 mg/cc) and shapes (cylinders and polyhedrons); 3) scanning craniofacial bones (N = 5) and dental tissues (N = 5), and ectopic minerals from humans (N = 3 each, pulp, salivary gland, kidney and prostrate stones, and penile and vascular plaques); 4) underscoring the effect of shape-factor (surface area-to-volume ratio) on MD of biominerals. Country Z is likely a net food exporter. C! So, what do you think is going to be the hardest part about understanding physiological density? Indeed, the US exports more food, in volume as well as value, than any other country. The current population density of Israel in 2023 is 415.70 Physiological population density is important because it gives a realistic idea of how many people need to be supported by cropland. Which country has the highest physiological population density? This is not far-fetched: the Sahara, after all, was once a grassland in wetter times of the Earth's history. WebOn any map showing population density, you can see clearly see which regions have many people per unit of land area, and which regions have very few, if any, inhabitants. Fig. Some figures state that a single person can survive for a year on crops from about half an acre (a large garden), and there are 640 acres in a square mile, so it looks like only 1450 people per square mile could be fed. Identify your study strength and weaknesses. Wealthy desert countries such as Qatar and Bahrain have barely any cropland, but they can also afford to import what they need. French intensive gardening has existed in France's urban areas for over 500 years, after all. Desalinization of seawater only works for wealthy countries because it is an extremely expensive technology. 3,268 Bahamas 7,692 Barbados 4,770 Belize 1,136 Costa Rica 3,046 Cuba 1,110 Dominica 3,704 Dom. Physiological population density can be changed if non-arable land can be made arable. As of 2020, the population density for the United Kingdom was 276 people per square kilometer, with London having by far the highest number of people per square km, at more than 5.7 thousand. Kazakhstan has only 69, and Canada is at only 78. Parsa A, Ibrahim N, Hassan B, van der Stelt P, Wismeijer D. Clin Oral Implants Res. Copyright 2022 Elsevier Inc. All rights reserved. Traditionally, arable land has meant rural land where plants grow in soil. However, we used the figures for Bangladesh, which is self-sufficient in rice (its staple crop, which is highly productive/acre), an amazing achievement for a country once hit by famines. But what if we changed the definition of crops? Which of the following measures the ratio of farmers to arable land? of the users don't pass the Physiological Population Density quiz! The map shows the number of people per unit of land. ~ @ Physiologic Population Density for Each of the World's States, Year 2000 JANUARY, 2000 PETER O.

The country with highest physiological population density is Singapore. Egypt, with around 110 million people and growing rapidly, has a moderate arithmetic population density of 289 people per square mile, around that of France or Turkey, countries with little problem feeding themselves. Set individual study goals and earn points reaching them. The key is making sure that we measure each of the methods because they are all going to be important to understand the rest of the world and how we will go about getting the food and shelter needed for the number of people in each country or city. Egypt, another desert country, is another story. is there any way out of this debacle? After all, theres no way that you could have people living only in the arable land area of a country. 2 Is arithmetic and population density the same thing? 3 - The prickly pear or nopal is one of many species of cacti that grow as weeds in Mexico and elsewhere but are also farmed for their delicious fruit. They doesnt have as many resources and they maybe, havent invested huge amount of money in technology to be able to support. Let's consider the top ten countries in the world in terms of their physiological population densities (PPD). United Nations projections are also included through the year 2100. What if we farmed desert plants or at least plants that don't need much water? Not with its arable land, since ten thousand people have to rely on each square mile of cropland. The physiological density formula used to calculate physiological density uses total area of farmland instead of total area like arithmetic density. To calculate physiological population density, divide the total population by area of farmland. The calculation helps determine how many people depend on an area of land for food. In the US, this is likely to be expressed as people per square mile, and in the rest of the world, as people per square kilometer or hectare. Quickly review popular literary works like. What is an example of physiological population density? Have all your study materials in one place. The world's largest food producer is _______. Federal government websites often end in .gov or .mil. MeSH Create beautiful notes faster than ever before. Fig. 2013 Mar 29;8672:867203. doi: 10.1117/12.2006939. You can calculate physiological population density by dividing the amount of arable land by the number of people. Create and find flashcards in record time. Accessibility Taiwan, at number 20 in the world, is the first country on the list for which the concept is quite useful. This threatens the ever-growing need for freshwater in urban areas as well as existing agriculture along the Nile. This method is simple to implement and maintains the biological integrity of the data. 5 d g E t " L w ? Physiological population density can be altered if more non-arable land is brought into cultivation, or crops with higher yields, such as rice, are planted. Please enable it to take advantage of the complete set of features! They have close to no cropland, people live almost entirely in urban areas or are nomadic herders or fishermen, and national income is used to buy crops on the international market.

The farming of cacti, particularly the nopal or prickly pear (Opuntia), provides nutritious food as well as a cash crop. Sixty percent of Bangladesh's land area is arable, the highest ratio in the world (Ukraine is 2nd, India is 5th). Next, find the amount of arable land (A) within that unit of land. They are able to low their, agricultural density and when they lower that they can have those people then, doing other jobs in society and producing in other areas. Bethesda, MD 20894, Web Policies Meanwhile, Country Z has a physiological density of 10 people per square mile. The different types of density are each important to understanding a specific area of the world, but physiological density is often considered real population density because it provides a better understanding and overview of the country it relates to. The country with the highest percentage of arable land is _______. Antilles 6,667 Nicaragua 1,209 Panama 1,443 Puerto Rico 29,411 Saint Lucia 6,250 St. Vin./Gren. Often, such maps utilize interpolation methods to estimate, across a given surface, In this AP Human Geography Review we will look at a physiological density definition to know what it really is and just how it relates to population density as a whole. All that is needed now is water. Implementation of dual- and triple-energy cone-beam micro-CT for postreconstruction material decomposition. Ho JT, Wu J, Huang HL, Chen MY, Fuh LJ, Hsu JT. Though. All three of these are used to get a more accurate understanding of the population density of any given area, but they will then be used in different ways according to the type. WebThe physiological density or real population density is the number of people per unit area of arable land. > N P M 7 ;, bjbjUU *X 7| 7| ! Yet cities are filled with spaces where food could be grown (and boy, would it cut down on transport costs!). And in China, it is common to see vegetable gardens filling every available niche in cities. Now, people still have large families, the population is growing rapidly, and little new farmland is available (though see below). Desalinization of seawater only works for wealthy countries because it is an extremely expensive technology. The Pyrenean micronation of Andorra survives on tourism revenue, as do the Indian Ocean nations of Seychelles and Maldives. people to do the same job. ( William Osei, Geography 4, Page 19) This density shows us how WebA thematic map is also called a special-purpose, single-topic, or statistical map. Quantifying physiological fat tissue in the organs is important to further assess the organs pathologic status. Remember, this is the number of people who are relying on one square kilometer of land to get all their food (though there is a lot of imports in these countries as well), and these numbers continue to rise. "Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land " as land under temporary What is the difference between physiological and agricultural density? In this case, it can be very misleading to assume that arithmetic population density is accurate and helpful if we are trying to determine the relationship between people and food consumption. Country Y is very likely a net food importer, at least of its fruits, grains, and vegetables. Higher MDs of physiologic and pathologic cortical bones (504-1009 mg/cc) compared to trabecular bone (82-212 mg/cc) were observed. And why not? A, Arithmetic density B. Physiological density C. Agricultural density D. Urban density E. Suburban density 2 See answers Can someone please help its due in an hour Advertisement adalynnemasoud Answer: In a completely agricultural region made up only of arable land, physiological and arithmetic density are equal. The world's largest food producer is _______. Learn more about our school licenses here. Before Egypt went through the demographic transition, farmers had large families, but populations grew quite slowly. 8 B N L _ > " $ * !y=] L Singapore tops the list when it comes to countries with the highest physiological density, at nearly 4 times that of the second highest (Hong Kong); Singapore has a density of 440,998 per square kilometer of arable land. Best study tips and tricks for your exams. By registering you get free access to our website and app (available on desktop AND mobile) which will help you to super-charge your learning process. Second, arable land is defined as all land cultivated for crops that are replanted after each harvest, which excludes land in permanent crops that are not replanted after harvesting (such as rubber, citrus, and coffee). What is the value of, Kevin examines the following data, which shows the balance in an investment account. Fig. In Netherlands, they have a very low agricultural, density because they have more urbanization, more people live in cities and they, also have invested in a lot of machines to help out the farmers. km of land area) - East Asia & Pacific. Welcome to the world of hydroponics, aeroponics, and other urban agriculture solutions. 1,316 Trinidad/Tob. However, Egypt's physiological population density is around 3500 per square mile, one of the highest in the world for non-city states. Those 273 people all have to do farming for just that one plat of land. Bone quality evaluation at dental implant site using multislice CT, micro-CT, and cone beam CT. Trabecular bone structural parameters evaluated using dental cone-beam computed tomography: cellular synthetic bones. Have all your study materials in one place. The idea here is that cities can and should provide much of their own food. A. Arithmetic density. Physiological Population Density: The ratio of people to farmland (arable land), usually applied to countries or country subdivisions. This isn't much higher than Bangladesh, but Bangladesh is a wet, tropical country with plenty of fresh water and no need for irrigation. Once salinization happens, agriculture is no longer an option. Arable land does not include land that could theoretically be farmed but has not been converted to cropland, such as a forest. French intensive gardening has existed in France's urban areas for over 500 years, after all. The first method used to measure population density is the arithmetic density, which is the total number of people in any given area as compared to one square unit of land. The https:// ensures that you are connecting to the If you have ever flown over the US, you may have seen this in action. Taiwan, at number 20 in the world, is the first country on the list for which the concept is quite useful. Methods: C. Agricultural density. The list below provides the Year 2000 physiologic density for each of those states, which will be a new data column in the book's next edition. The central objectives of this study are: 1) to delineate mineral density (MD) values, and 2) generate spatial MD maps of various physiologic and pathologic biominerals, and 3) propose a standardization protocol within the safe-operating zone of a CT scanner that underpins normalization of absorbed dose to shape and density of tissues. Seven maps/datasets for the distribution of various populations New Caledonia ---- Papua New Guinea ---- Samoa 957 Solomon Is. Physiological density looks at ratio of total population to arable land. Get access to all 7 pages and additional benefits: help please The population of a small town is decreasing at a rate of 3% each year. A" i" " " " # =# i# # # # # $ /$ O$ z$ $ $ $ % J% y% % % % % &. PMC In areas with no cropland whatsoever, there is no physiological population density. AP Human Geography requires that you understand the differences between the two types of population density and in which cases each is informative for demographic studies. 3641, Table I-1 (Area and Demographic Data for the World's States) provides only the arithmetic density for each of the world's states (the ratio of its total population to total land area). They have high-tech Combines, Tractors, Reapers etc. StudySmarter is commited to creating, free, high quality explainations, opening education to all. Year Population 0 7,900 1 7,584 2 7,281 3 6,989 4. WebAlthough the arithmetic density is the most common way of measuring population density, several other methods have been developed to provide alternative measures of population density over a specific area. Most of Egypt's population and crops can only exist along a narrow ribbon of land and water, the Nile Valley and Nile Delta. Polynesia 14,286 Guam 8,658.2 Marshall Is. The recent numbers are shown in this table: Week 0=40 people Week 1=60 people Week 2=90 people, The population of a small town is decreasing at a rate of 4% each year. Arithmetic density gives us the population density across an entire area, whether cropland or something else. Significance: More and more people depend on the same amount of cropland. Without rainwater to flush out mineral salts, avoiding salinization of irrigated soil can be difficult. Netherlands has more efficient farming methods. This means people who work the earth on specific plots of land that are used for this. Guiana 588 Guyana 461 Paraguay 598 Peru 1,841 Suriname 664 Uruguay 611 Venezuela 1,784 NORTH AFRICA/ SOUTHWEST ASIA Afghanistan 864 Algeria 1,149 Bahrain 222,222 Djibouti Egypt 8,899 Eritrea 855 Iran 1,051 Iraq 1,135 Israel 4,559 Gaza 92,307 West Bank ---- Jordan 3,499 Kazakhstan 128 Kuwait ------ Kyrgyzstan 925 Lebanon 5,000 Libya 898 Morocco 790 Oman ----- Qatar 11,628 Saudi Arabia 1,289 Somalia 2,353 Sudan 647 Syria 830 Tajikistan 1,934 Tunisia 868 Turkey 702 Turkmenistan 900 United Arab Em ----- Uzbekistan 1,764 Western Sahara ----- Yemen 2,763 SUBSAHARAN AFRICA Angola 1,329 Benin 1,153 Botswana 640 Burkina Faso 874 Burundi 1,331 Cameroon 646 Cape Verde Is. It measures the total number of people and divides them between the total amount of farmable land. Physiological Population Density Formula First, find the Epub 2013 Dec 11. More about Physiological Population Density. Not with its arable land, since ten thousand people have to rely on each square mile of cropland. official website and that any information you provide is encrypted She has a graduate student, Kevin, to assist her. Can it feed itself? 2013 Nov 9;12:115. doi: 10.1186/1475-925X-12-115. The central objectives of the study are: 1) to delineate mineral density (MD) values, and 2) generate spatial MD maps of various physiologic and pathologic biominerals, and 3) propose government site. Test your knowledge with gamified quizzes. Here are the catches: Aquifers are problematic because, if they aren't recharged fast enough, often the case in deserts, they will run dry. Set individual study goals and earn points reaching them. And in China, it is common to see vegetable gardens filling every available niche in cities. WebAP Human Geography Review - Unit Two. Physiological density is a measure of the total population of a country or region to the area of arable land. The higher the population density we find from this method, the faster the arable land is going to be used up or reach its output limit. The country with the world's highest physiological population density is _______. Many people know what it means to refer to population density, but few have actually heard the term physiological density. Objectives: In the term of Egypt, one of the thing that shows us is there is a lot of land in Egypt for people, to live they are not all clustered together they can be spread out. The country with the highest percentage of arable land is _______. Its important to keep in mind that averages play an important role in physiological density. In Egypt, this could mean turning Red Sea or Mediterranean saltwater into freshwater, using water piped from the Nile, buying freshwater from another country, tapping into aquifers, or some combination. It also does not include pasture and grazing land unless part of a crop rotation system (in cases where animals are pastured on fallow cropland). and to use those kinds of developed machines they can, cultivate their land very easily. The physiological density or real population density is the number of people per unit area of arable land . The difference between the two types of density is important in regions with both arable land and non-arable land. Brunei is an oil-rich rainforest nation that protects its forests rather than turning them into farms. An increase in shape-factor increased the CBCT error in MD measurement and revealed that the scanner resolution is dependent on the absorbed dose and shape-factor of detectable features. Meanwhile, agricultural population density considers the ratio of farms (and/or farms) to arable land. Simulate how different MCQ and FRQ scores translate into AP scores. The semi-deserts of Nebraska's High Plains, underlain by the Ogallala Aquifer, pump fossil water from the last Ice Age to the surface to make land arable that otherwise would only be suitable for grazing. Of course, we made this a simple example just for the sake of understanding it, but in reality, the numbers would be much higher. The population density of Denmark in 2020 was 135.73 people per square kilometer, a 0.51% increase from 2019. Arable land does not include land that could theoretically be farmed but has not been converted to cropland, such as a forest. 1 - Rice farmers in Bangladesh. It all makes perfect sense once you realize we are measuring physiological population density and not arithmetic population density. In the textbook on pp. doi: 10.1088/1361-6560/abc367. The concept of physiologic density is discussed in several chapters. Small population. The Pyrenean micronation of Andorra survives on tourism revenue, as do the Indian Ocean nations of Seychelles and Maldives. While its farming areas are critical to providing food for its population, Taiwan does not have nearly enough arable land to do so and relies heavily on food imports: it is equivalent to Country Y in the example above. Create the most beautiful study materials using our templates. Egypt, with around 110 million people and growing rapidly, has a moderate arithmetic population density of 289 people per square mile, around that of France or Turkey, countries with little problem feeding themselves. Label. In this case, it can be very misleading to assume that arithmetic population density is accurate and helpful if we are trying to determine the relationship between people and food consumption. More and more people depend on the same amount of cropland. 8600 Rockville Pike In the US, this is likely to be expressed as people per square mile, and in the rest of the world, as people per square kilometer or hectare. For example, study questions have considered a number of factors. The countries with top ten physiological population densities are: Tourist spots, city-states, and desert nations. A comparative study of trabecular bone micro-structural measurements using different CT modalities. 2008 Nov;35(11):5030-42. doi: 10.1118/1.2987668. I used the Rubenstein 12th edition maps for reference, though the outline maps were created by myself. Are you a teacher or administrator interested in boosting AP Human Geography student outcomes? 1: Bangladesh (https://commons.wikimedia.org/wiki/File:Farmer_of_bangladesh.jpg) by Ashef Emran is licensed by CC-BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/deed.en), Fig. The map shows the number of people per unit of land. What if they could grow on a wall, a road, or a vacant lot? The population density of Denmark in 2021 was 136.40 people per square kilometer, a 0.49% increase from 2020. What it means is that for every one square kilometer of arable land in the country, there are 78 people somewhere in the country. Five are desert countries, four of these wealthy emirates in Southwest Asia, and one, Djibouti, is a state based around a port in the Horn of Africa. If you didn't know this, you might think Taiwan can feed itself. Med Phys. A higher physiological density suggests that the available agricultural land is Which of the following is not a way that Egypt could increase its arable land? Taiwan's APD of 1849 people/square mile is a fifth of its PPD of almost 10000 people/square mile because much of Taiwan consists of high, steep mountains that are largely useless for crop cultivation. Test your knowledge with gamified quizzes. The idea here is that cities can and should provide much of their own food. 2: Egypt density (https://commons.wikimedia.org/wiki/File:Population_density_of_Egypt_governorates.png) by Austiger is licensed by CC-BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/deed.en), Fig. Keywords: NCI CPTC Antibody Characterization Program. Proc SPIE Int Soc Opt Eng. Sixty percent of Bangladesh's land area is arable, the highest ratio in the world (Ukraine is 2nd, India is 5th). For example, to find the arithmetic density for the US, you divide the amount of people (300 million) by the amount of land (3.7 million square miles) and you get 80 people per each square mile. Make sure you also know how physiological density is affected, for example, by countries that have lower levels of arable land or higher levels of population (or both). If you are a country with lots of deserts, a single river, and a large population that is growing quickly, we're probably talking about you. Upload unlimited documents and save them online. Line Bar Map. Free and expert-verified textbook solutions. Water becomes scarcer and scarcer. United Nations projections are also included through the year 2100. Once salinization happens, agriculture is no longer an option. This eclectic list is 1) Singapore, 2) Bahrain, 3) Seychelles, 4) Kuwait, 5) Djibouti, 6) United Arab Emirates, 7) Qatar, 8) Maldives, 9) Andorra, and 10) Brunei. To understand a physiological density definition, lets look at an example. Egypt's physiological population density of 3500 people per square mile of arable land is over ten times higher than its arithmetic population density of 289/square mile. When we view Hong Kong, we see 131,101 and Djibouti gets us 51,861. As urban areas grow larger and larger, buildings, roads, and other infrastructure overwhelm agricultural land, driving physiological population density even higher. Over 50% of the land in the country is arable, so can country X feed itself? Upload unlimited documents and save them online. Country X might not be self-sufficient in food, then. ! " In a completely agricultural region made up only of arable land, physiological and arithmetic density are equal. Its 100% free. Small population. The .gov means its official. Five are desert countries, four of these wealthy emirates in Southwest Asia, and one, Djibouti, is a state based around a port in the Horn of Africa. Next, find the amount of arable land (A) within that unit of The difference between the two makes a big difference! Thus, people who stay in Egypt must find other trades, and their numbers tend to swell the cities. By better understanding who is relying on each region of the world, we can better allocate resources and understand how current resources are already being allocated. AP Human Geography requires that you understand the differences between the two types of population density and in which cases each is informative for demographic studies. Food and Agriculture Organization and World Bank population estimates. km of land area) - European Union. This threatens the ever-growing need for freshwater in urban areas as well as existing agriculture along the Nile. and transmitted securely. One can find this by dividing the total number of people in an area by the total land area. Students will use images, U.S. Census Bureau data, and interactive maps to visualize and calculate arithmetic (population), agricultural, and physiological densities at ! Wealthy desert countries such as Qatar and Bahrain have barely any cropland, but they can also afford to import what they need. Without rainwater to flush out mineral salts, avoiding salinization of irrigated soil can be difficult. If you didn't know this, you might think Taiwan can feed itself. But there is a catch (several, actually) to altering your physiological density by increasing your amount of arable land. 410 and 417, requires a noteworthy adjustmentfrom 4020 to 3487). This isn't much higher than Bangladesh, but Bangladesh is a wet, tropical country with plenty of fresh water and no need for irrigation. At the beginning of each year, $2,000 is deposited into the account (starting with $2,000 for the first year). the number of people living in each unit of area (such. The countries with top ten physiological population densities are: Tourist spots, city-states, and desert nations. They have close to no cropland, people live almost entirely in urban areas or are nomadic herders or fishermen, and national income is used to buy crops on the international market. The US, at number 173 on the list, has one of the world's lowest physiological population densities. Which of the following types of data are shown in the map? 1 - Rice farmers in Bangladesh. Physiological population density can be altered if more non-arable land is brought into cultivation, or crops with higher yields, such as rice, are planted. The semi-deserts of Nebraska's High Plains, underlain by the Ogallala Aquifer, pump fossil water from the last Ice Age to the surface to make land arable that otherwise would only be suitable for grazing. Arithmetic density is also known as real density while physiological density is the number of people per unit of arable land. It is also number two in total arable land area in the world (after India, which has three times the population of the US), so, not surprisingly, like County Z in the example above, the US is a net food exporter. If we look at the arithmetic density, we come up with a population density of 1 person per kilometer (10,000/10,000). Phys Med Biol. Of the countries which make up the United Kingdom, England the most densely populated at 1 \ > i $a$ !, :, I s This is because of Singapore's total land area of 263 square miles, only two square miles are arable land. Over 50% of the land in the country is arable, so can country X feed itself? Line Bar Map. First, some minor numerical inconsistencies may be discerned because the following list is based on a newer data set of arable land (only Bangladesh, covered on pp. 5 What is an example of physiological density? Years Population O 8,500 1 8,245 2, Suppose an account pays 6% interest that is compounded annually. The farming of cacti, particularly the nopal or prickly pear (Opuntia), provides nutritious food as well as a cash crop. Identify your study strength and weaknesses. [Online] 21 (2), 317331. Irrigation needs water from somewhere. License : CC BY-4.0. Physiological Population Density Formula First, find the total population (P) of a unit of land (such as a county, state, or country). Food and Agriculture Organization and World Bank population estimates. There wouldnt be enough room in many of them, and that would leave large open spaces.
