![]() ![]() Without this critical information, the engineer my design something that could fail under heavier than expected usage.Ī population density will change when the number of people living in an area increases or decreases. Knowing the population density allows the engineer to design the infrastructure to handle that population or rate of usage the infrastructure would see. When engineers design bridges, sewage, and other infrastructure for areas, one of the essential design considerations is population density. One example of this importance can be seen in urban planning. Population density is a key metric in understanding not only the economics and logistics involved in an area but also the culture and the mindset of the people living there. 6 Things to Know About Population Denisty These units can be expressed in per thousands of people when looking at very dense areas, such as New York, like the example above shows. ![]() In most cases, population density is present in the number of people per square mile, or the number of people per square kilometer. For this problem, New York City is found to have a total size of 302.6 square miles.įinally, calculate the population density using the formula D = P/A = 8,419,000 / 302.6 = 27,822.20 people per square mile. Next, determine the total area of the city. Note that this is only the borough of New York City, and does not include the surrounding metropolitan area. In this example, we will use the city of New York as the area.Īs of 2019, the city contained 8.419 million people. The following example problem outlines the steps required for calculating a population density.įirst, determine a specific area that is to be analyzed. Population Density DefinitionĪ population density is defined as the total number of people per unit of area. When analyzing populations, volumes don’t make much sense to look at, so we use area. Normally in math, density is a mass or number per unit volume. Another positive of living in higher density city environments is the efficiency of commuting due to shorter journeys.In the case of population density, we use a total number of people per unit area. The University of Oxford and the University of Hong Kong found that those who lived in the built-up areas of 22 British cities had a lower body mass index and took more exercise than those who lived in suburban areas. However, there have been studies to suggest living in a densely populated area can increase health and happiness. Crowding can also present many health concerns such as a higher risk of spreading diseases. Officials often struggle to find adequate solutions to provide infrastructure, including sanitation, housing and transportation. One of the main challenges of overcrowding is the problems it presents to governments and policymakers. Problems With Overcrowdingĭensely populated locations have positive and negative attributes. ![]() It is Europe's most densely populated town but one of Paris' richest suburbs. For example, when Poland joined the European Union in 2004, many workers migrated to the United Kingdom for an abundance of openings and better wages.Įurope enters the list at number ten with Levallois-Perret, a city in north-central France about 6 km from the center of Paris. Economic factors such as employment opportunities (a pull factor) can also influence migration and population density. Places with high political unrest (a push factor), such as Afghanistan, have a low population density as many people migrate. These are sometimes referred to as push or pull factors. Human factors that influence population density include political, economic, and social issues. Human and physical factors influence population density they both influence the growth and change of an area. But first, it is important to know about the factors that influence population density. What makes these Philippine cities so packed with people and which are the other densely populated cities of the world? The article attempts to answer these questions. Coming to the world's most populated cities (city proper), Manila, Pateros, and Mandaluyong, all these cities in the Philippines in Southeast Asia, occupy the top three spots. When comparing this information to other countries' statistics, it tells us that Monaco is the world’s most densely populated place. For example, Monaco, a principality located on France’s Mediterranean coast, is 2.02 square kilometers in size and has around 26,000 people per square kilometer. It can be used as a statistic to show how many people live in that specific area. Population density is defined by the number of people living in each unit of area. ![]()
