Population is a commonly used term to denote the number of people living at a place. The density of population in different parts of the world varies drastically owing to several reasons.
Uneven Distribution of Population
Population on earth is distributed unevenly. While there are certain countries that are facing the problem of population explosion others are sparsely populated. This is not just the case with the human population it also holds good for animals and other organisms. At certain places you will see greater number of animals while at some places you will hardly find any.
Things that Impact Population Density
The density of population in any area is calculated by dividing the total number of people by the area they are living in. The density of population differs in different places owing to several reasons. Some of the factors that influence the density of population in an area are as follows:
Climate
Places with extremely hot or cold climates are sparsely populated. On the other hand, those that enjoy moderate climate are densely populated.
Resources
The areas with good availability of resources such as oil, wood, coal, etc are densely populated while those that lack these basic resources are sparsely populated.
Political Environment
Countries that enjoy a stable government and a healthy political environment are densely populated. These countries attract immigrants from other countries there by populating the area. On the other hand, countries with poor or unstable government see many people leaving at the availability of any good opportunity elsewhere.
Standard of Living
First world countries such as U.S.A. attract a lot of immigrants as they offer much better packages and a good standard of living to people. People from different parts of the world immigrate to such countries. This is the reason why the density of population in such countries is increasing.
Conclusion
Even though certain places around the globe have low density of population, the overall population of the country has increased over the last few decades and is likely to increase manifolds in the times to come.
Answer:
beta mate,
here's your answer
The world's population stands at about 5.3 billion. It increases by about 90 million/year. 90% of this growth is in the developing world where about 75% of the world population live. In Arab countries, the population is growing 2.6%/year and total fertility rates (TFRs) stand 5 whereas the TFR for the entire world is a bit 3. Much of the growth has occurred in cities, e.g., Cairo, where the population has outpaced basic services. Cities require food and fuel thereby stressing rural areas which rural-urban migration only exacerbates. Population growth and distribution have a more profound and long term effect on the planet than does the destruction of rain forests and desertification. Indeed they contribute heavily to these very problems. Even though people have the right to decide how many children they have and their spacing, they also have the responsibility, as Islam professes, to have only number of children they can afford. Likewise governments have the right and responsibility to develop population policies each suited to the individual nation's needs and conditions. Each government must set policies that improve the role and status of women, such as ensuring literacy and education for girls and women.
