What is concentration in human geography?
Concentration (geography) (r): The geographic location of a specific cluster or dense group, e.g. of ethnics, types of buildings, types of natural features (such as mountains, lakes, or forests).
How is geographic concentration measured?
Concentration Ratio
- The simplest method to quantify geographic concentration is computing the share of exposure (EAD) held by the k largest geographies or regions in the portfolio relative to total exposure.
- Weaknesses of this index are that the choice of k is arbitrary (e.g., country level, cluster of countries etc.)
What is concentration index?
The concentration index is defined as twice the area between. the concentration curve and the line of equality (the 45-degree line). So, in the case. in which there is no socioeconomic-related inequality, the concentration index is. zero.
What is pattern in geography?
A spatial pattern is a perceptual structure, placement, or arrangement of objects on Earth. It also includes the space in between those objects. Patterns may be recognized because of their arrangement; maybe in a line or by a clustering of points.
What is an example of concentration in geography?
Two examples of concentration are scattered and clustered. Dispersed concentration is when objects in an area are relatively far apart. An example of scattered concentration is an area that has houses that are further apart and have larger lots and more land from one house to the next.
What is the difference between concentration and density in geography?
Concentration is the spread of objects in a given area, density is the frequency of objects in a given area,and pattern is the arrangement of objects in a given area.
What is concentration curve?
The concentration curve plots the cumulative percentage of the health variable (y- axis) against the cumulative percentage of the population, ranked by living standards, beginning with the poorest, and ending with the richest (x-axis).
What is population concentration index?
The concentration index quantifies the distribution of the population at a point in time. As seen in Figure 3, the concentration index is declining, which indicates that the U.S. population is becoming somewhat more evenly distributed among the states.
What is diffusion in geography?
In geography, the term diffusion refers to the spread of people, things, ideas, cultural practices, disease, technology, weather, and other factors from place to place.
What are the 3 types of geography?
There are three main strands of geography:
- Physical geography: nature and the effects it has on people and/or the environment.
- Human geography: concerned with people.
- Environmental geography: how people can harm or protect the environment.
What is concentration of population?
Population density is the concentration of individuals within a species in a specific geographic locale. Population density data can be used to quantify demographic information and to assess relationships with ecosystems, human health, and infrastructure.
What is the difference between density and concentration in geography?
Concentration is the spread of objects in a given area, density is the frequency of objects in a given area,and pattern is the arrangement of objects in a given area.
What is concentration and density?
Definition. Density is the ratio between mass and volume of substance. Concentration is the ratio between amount and volume of a substance.
What is concentration and effect curve?
Pharmacology A graph of the relationship between exposure concentration of a drug or other chemical and the graded effect that it produces.
How do you draw a concentration curve?

Where is the population concentrated?
Most of the world's population is concentrated in China, India, and the surrounding countries. The United States is similar to the world map in that about half of the national population lives in yellow areas and half live in the black areas.
What is called diffusion?
Diffusion is defined as the movement of individual molecules of a substance through a semipermeable barrier from an area of higher concentration to an area of lower concentration (34).
What is assimilation in geography?
Assimilation is defined as the complete integration of someone of minority status into a dominant culture. For example, if you're a Buddhist Korean immigrant who moves to the United States, you are entering this country as a statistical minority.
Who is called father of geography?
scholar Eratosthenes The ancient Greek scholar Eratosthenes is commonly called the "father of geography" for he was the first to use the word geography and he had a small-scale notion of the planet that led him to be able to determine the circumference of the earth.
What are the 2 main branches of geography?
Together, however, the many branches of geography improve our understanding of our planet and its people. Geography's two main branches are physical geography and human geography. Geographers identify and locate major physical and human geographic features of various places and regions in the world.
What is density in geography?
Density is the number of things—which could be people, animals, plants, or objects—in a certain area. To calculate density, you divide the number of objects by the measurement of the area. The population density of a country is the number of people in that country divided by the area in square kilometers or miles.
How do you determine concentration?
Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.
What is concentration effect relationship?
Concentration–effect relationships concerns groups of patients and indicate the probability of a given response (therapeutic/toxic) at a given concentration.
Which government concentration effect refers to the increasing activities of which of the following?
Answer: In the study of inhaled anesthetics, the concentration effect is the increase in the rate that the Fa (alveolar concentration)/Fi (inspired concentration) ratio rises as the alveolar concentration of that gas is increased.
How do you find the linear range in Excel?
Select “Linear” under “Trendline Options”. Also select “Display Equation on Chart” and “Display R-Squared Value on Chart”. You should now see a dotted line drawn through your data points and a text box next to it with the best-fit linear equation and the R2 value.
What is a concentrated population?
The higher the index, the more the population is concentrated. At an index of zero, the population would be evenly distributed all across a nation, state, county, or city. An index value of 100 would have all population concentrated within one subdivision of the larger entity.
What does concentration of population mean?
Population density is the concentration of individuals within a species in a specific geographic locale. Population density data can be used to quantify demographic information and to assess relationships with ecosystems, human health, and infrastructure.
What is the concentration of gradient?
A concentration gradient occurs when the concentration of particles is higher in one area than another. In passive transport, particles will diffuse down a concentration gradient, from areas of higher concentration to areas of lower concentration, until they are evenly spaced.
What is accommodation and assimilation?
Assimilation is the process of using or transforming the environment so that it can be placed in preexisting cognitive structures. Accomodation is the process of changing cognitive structures in order to accept something from the environment. Both processes are used simultaneously and alternately throughout life.
What is assimilation and acculturation?
Assimilation is a two-way process, and the majority culture is changed as well as the minority culture. Acculturation occurs when the minority culture changes but is still able to retain unique cultural markers of language, food and customs.
