Population distribution and density

Module 5

population distribution

  • It is easy to analyse the words population distribution . Population refers to people and distribution refers to where these people live on earth. The map below indicates that people are not distributed evenly across the globe. In certain areas there is a larger concentration of people than elsewhere.

1. Factors that influence the movement and settlement of people

There are approximately 6 milliard (6 000 million) people on earth and they inhabit only approximately 15% of the surface of the earth (see circle graph).

There are certain factors that influence the choice of where to live.

N atural factors:


Pleasant temperatures (between 10 ºC and 30 ºC) and comfortable humidity attract people. Extreme circumstances such as windstorms or very high rainfall should not prevail.


People go where their basic needs can be addressed. Food and water are the most important of these needs.

Human factors


People will settle where they can earn money (often in spite of an unpleasant climate).

Political decisions:

Decisions made by the government of a country can make circumstances very unpleasant for the inhabitants, which cause a migration of people elsewhere.

AN INTERESTING FACT: - Approximately 90% of the world population lives in the Northern Hemisphere.

- Approximately 60% of the world population lives in areas that are lower than 200 m above sea level.

Activity 1:

To study a map of the world as a group to acquire information

[lo 1.1]

  • Study the map of the world as well as maps in your atlas. Find possible answers to the following questions:
  • What are the reasons for the low density of population at a, b and c?
  • Why is the population at d and e also sparse?
  • Does the Amazon River in Brazil have anything to do with the density of _______________population in that country? (Explain)
  • Explain the reasons for the density of population in the North Eastern corner of __________________________Africa.
  • Would you say that Australia is an urbanised country?

2. The choice: in the city or in the country/rural area?

  • Most of the grade 6 learners who are reading this, live in a city or in a large town! We know this because more than half of our country’s population is URBANISED . This means that more than 50% of our people live in large towns or cities. This is determined by means of a census .
  • When you examine the map on page 3 it becomes clear that people are not distributed evenly over the globe, but are concentrated in certain parts. This has not always been the case. From the very beginning – even in Biblical times – there were cities, although most people did not live there. Only over the past 50 years the number of people in South Africa living in cities increased, and decreased in rural areas. These figures vary from country to country.
  • In the migration between urban and rural areas, technology has always played a significant role. As new opportunities for work develop, people change their workplace and often the place where they live. This means that people generally move from rural to urban areas to look for new employment opportunities.
  • Technological development results in people being replaced by machines in the workplace and that the people who lose their jobs, move to the cities where there are more employment opportunities.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
