As of today’s date, the world population is estimated by the United States Census Bureau to be 271 billion/7271 million. The US Census Bureau estimates the 7 US billion/7000 million number was surpassed on 12 March 201 According to a separate estimate by the United Nations, Earth’s population exceeded seven US billion in October 2011, a milestone that offers unprecedented challenges and opportunities to all of humanity, according to UNFPA, the United Nations Population Fund.
During the European Agricultural and Industrial Revolutions, the life expectancy of children increased dramatically. The percentage of the children born in London who died before the age of five decreased from 75% in 1730-1749 to 38% in 1810-182 Between 1700 and 1900, Europe’s population increased from about 100 million to over 400 million. Altogether, the areas populated by people of European descent comprised 36% of the world’s population in 190
AIDS has played some role in temporary population decline; however, available data suggest that, even with high AIDS mortality, fertility rates in Africa are high enough to ensure the overpopulation trends continue. AIDS has contributed to a population explosion in Africa as money from fertility reduction programs was redirected into the HIV/AIDS crisis; African fertility rates have actually increased in the past two decades while population grew by over 50%.
Scholarships come in many forms and types. There are those that are offer to some sectors of society, specific intellectual capacity, athletic excellence, and more. Meanwhile, there are also scholarships that are specifically designed to minorities. Scholarships for minorities are made to keep those little portions of the population educated even if the students cannot afford to pay for their education.
A declining population (regardless of the cause) can also create a labor shortage, which can have a number of positive and negative effects. While some labor intensive sectors of the economy may be hurt if the shortage is severe enough, others may adequately compensate by increased outsourcing and/or automation. Initially, the labor participation rates (which are low in many countries) can also be increased to temporarily reduce or delay the shortage. On the positive side, such a shortage increases the demand for labor, which can potentially result in a reduced unemployment rate as well as higher wages. Conversely, a high population means labor is in plentiful supply, which usually means wages will be lower. This is seen in countries like China and India.
France was historically Europe’s most populous nation. During the Middle Ages, more than one quarter of Europe’s total population was French; by the 17th century, this had decreased slightly to one fifth. By the beginning of the 20th century, other European nations, such as Germany and Russia, had caught up with and overtaken it. However, the country’s population sharply increased with the baby boom following World War II.
Other major groups, from large population contributor down to the least were China, Italy, Vietnam, India, Philippines, Greece, Macedonia and South Africa. They complete the top ten immigrants in Australia. Other countries with notable number in the country were Germany, Malaysia, Netherlands, Lebanon, Indonesia, US and so forth. Sudanese born and other African nationalities are the fastest growing settlers in Australia.
Analysing data for 40 countries, Lee et al. show that fertility well above replacement and population growth would typically be most beneficial for government budgets. However, fertility near replacement and population stability would be most beneficial for standards of living when the analysis includes the effects of age structure on families as well as governments. And fertility moderately below replacement and population decline would maximize standards of living when the cost of providing capital for a growing labour force is taken into account.
A declining population due to low fertility rates will also be accompanied by population ageing which can contribute problems for a society. This can adversely affect the quality of life for the young as an increased social and economic pressure in the sense that they have to increase per capita output in order to support an infrastructure with costly, intensive care for the oldest among their population. The focus shifts away from the planning of future families and therefore further degrades the rate of procreation. The decade long economic malaise of Japan and Germany in the 1990s and early 2000s is often linked to these demographic problems, though there were also several other causes. The worst case scenario is a situation where the population falls too low a level to support a current social welfare economic system, which is more likely to occur with a rapid decline than with a more gradual one.
