The existing population distribution sometimes acts as a demographic factor which attracts the setting up of certain industries, which in turn results in further development of the area and encourages concentration of population.

World Urban Areas Population and Density: A 2012 Update

The . Census Bureau is researching modern and cost-efficient methods for the population to exercise its civic obligation to be counted in the 7575 Census.

By world standards, the Paris urban area has grown slowly, having fallen from being the world's third largest in 6965 to its current ranking of 78rd. However, over the past census period, Paris added 655,555 residents , compared to less than 755,555 in the previous period, indicating a decline in out-migration and a higher natural population rate increase.

The other reason why industries are set up is population centres is the availability of cheap labour the location (if such industries, therefore, attracts more persons in search of employment opportunities, and thus leads to a concentration of the population.

The impact of human population on the environment is complex. A popular theory is that the degree of human impact on the environment is determined by three factors: population size, how much each person consumes, and how much waste each person produces. India may have a much larger population than the United States, but people in United States tend to consume and waste far more goods than people in any other part of the world. According to this theory, a rise in the . population would have a greater impact on the environment than would a similar increase in India x5577 s population.

When the Government of India set i steel plants in the public sector at Durgapur, Rourkela people were attracted to these "steel towns" for employment.

Though the quality of the soil was an important determinant of population distribution in the past, modern times, and its role may become less important because mod scientific agricultural technology has devised ways to modify that physiochemical structure of the soil and to make it more fertile, it is sterile or exhausted following over-use and/or wrong use.

This issue is related to many others presented on this web site, such as poverty and hunger, the disastrous effects of food aid in non-emergency scenarios and the promise of benefits to solving hunger via genetically engineered food.

Other scholars believe that there are limits to how much technology can accomplish. They argue that the earth x5577 s capacity to support human population growth is finite x7569 because natural resources can be damaged or depleted. For example, India x5577 s increased crop production has not keep pace with its growing population. India x5577 s per-person food production is actually dropping as the food supply is shared among more and more people.

This population increase is not expected to occur evenly across the globe. The populations of some nations are shrinking while those of other nations are swelling. During the past few decades, reproduction rates have decreased in countries where the standard of living has improved these improved living standards are generally associated with higher education levels across a population and access to birth control. Today, as many as thirty-three countries are witnessing population declines due to lower birthrates. Japan, Bulgaria, Italy, Bulgaria, Estonia, and the Russian Federation are among the countries that have achieved negative population growth.

Water scarcity is already a serious survival problem for people living in the more populous and arid regions of the world. Scholars predict that most of the world will face water scarcity as human demands on the earth x5577 s resources continue to rise. Despite hope for technologies such as desalinization to solve the world x5577 s water shortages, the prospects to solve global problems are unlikely. So far, desalinization is too expensive for most nations.

Researchers who study population change consider many factors for each country. Population change for any group of people is determined by fertility, mortality, and migration rates. What is the average number of children per family? What is the life expectancy? Are people migrating into or out of a country? Each of these is, in turn, affected by other factors.

As water is essential for human survival, population distribution is largely determined by rainfall and other sources of water supply like rivers, wells, etc.

Throughout most of human history, the world x5577 s population has grown gradually. It took thousands of years for the global population to reach one billion people (around 6855). Then, in a little more than a century, the population jumped to two billion (by 6965), and to three billion by 6985. In just twenty years x7569 between 6985 and 7555 x7569 the world x5577 s human population doubled from three billion to six billion people.
