In 1950 there were only 131 million people of age 65 and older; in 1995 their number had almost tripled and was estimated at 371 million. Between now and 2025 the number will more than double again; and by 2050 we will probably have more than 1.4 billion elderly The percentage of elderly increased from 5.2 in 1950 to 6.2 in 1995. By 2050 one out of ten people worldwide will be 65 years of age or more. While currently population aging is most serious in Europe and Japan, China will experience a dramatic increase in the proportion of elder people by the middle of the next century. This is largely due to the country's success in family planning, which rapidly reduced the relative size of birth cohorts since the 1970s.The future number of people on the globe, evidently, is an important antropogenic factor of global change.
There are 4.5 billion today. World population is growing at an enormous rate. The world is going to add a billion people in the next eleven years, that's 224,000 every day! Experts say there will be at least 1.65 billion more people living in the world in the next twenty years. We must understand what these numbers mean for the U.S. Let's look at the question of jobs.
From 1 A.D. to 1650 A.D. the population grew to only five hundred million, this is mostly due to the plague in the 1300’s killing around 75 million people. But with breakthroughs in sanitation, agriculture, and many other technologies the world population doubled from five hundred million to over one billion (Curtin). By 1900 the population had grown to over 1.5 billion, and by 1960 to 3 billion. After 1960 it only took 40 years for the population to double to 6 billion unlike before when it took several hundred years or more. (U.S. Census Bureau).
The Population Explosion According to the Population Reference Bureau, in 1991, there were about 5.4 billion people in the world. The global birth to death rate was 27/9, meaning that for every person that dies, three more babies are born. From 1990 to 1991, the population increased by 95 million people, and now has continued to grow at that rate. This may appear to be no danger, but if one were to think of it as a pond doubling its amount of lily pads for 40 days, they'd see it differently. It would start out with one lily pad, the next day it has two, and on the 39th day it is half filled.
This is the amount of people on earth May 8, 2004 at 8:39:47 PM; this number is constantly rising at about 8 million people per month. At the present rate, the population will rise to a point that it will max out the earth’s carrying capacity leaving humans with a lack of resources and space. Soon people will have to learn to survive off artificial resources to substitute for the inability for agriculture to keep up. “In 1950 the population of the world was placed at roughly 2,400 million, the rate of growth of the world's population is greater than ever before in history, and the successive net additions, period by period, are breath-taking.” (Hertzler 9) In 1974 the United Nations held the World Population Conference at which it was determined that a solution for the crisis was needed, it was also decided that all countries would create a population policy that would attempt to help the countries deal with social, economic and cultural development. Although the United States has a large population problem to deal with of its own, underdeveloped countries hold 80 percent of the worlds population and are unable to provide methods of birth control, leaving people no choice other than abstinence.
Population: The Growing Problem History of Earth's Population From the beginning of time until 1850, the world population had been steadily growing until it finally reached the point of one billion people. Hurray for our species, we are successful and have been able to make adaptations in order to survive! Then, only 80 years later, the world population doubled to a whopping 2 billion citizens. After that, the doubling time was sliced once again. By 1960, just thirty years later, three billion people called Earth "home."
Around 1800, the population was around 1 billion human beings on Earth (Easton, 2014). By 1950, the population had grown to over 2.5 billion (Easton, 2014). The growth most certainly did not stop there. The population had surpassed 7 billion by 2011 (Easton, 2014). Growth trends are predicting it to be over 8 billion by 2025 and, as stated in by the World Population Prospects within the Easton text, 9 billion by 2050 (Easton, 2014).
Current evidence shows that this theory may not be far from the truth. The world population reached 6 billion on October 12, 1999, and is expected to reach 9.3 billion by 2050! The impact of population growth is already felt by a majority of nations. The U.S. population has increased by 78% since 1950. Growing at 3,000,000 per year, U.S. population is expected to approach half a billion people in 50 years.
Here is some data already illustrates these new changes. Developing markets accounted for 60% of incremental world GDP from 2000 to 2010. Over the next decade, most of the world’s expected population growth of approximately 750 million people will be in these economies . Emerging market hedge fund capital reached a record new level in the first quarter of 2011 of $121 billion，which only have 0.4 percent of word outward foreign direct investment(FDI) and 15.8 percent by 2008 .And the numbers of the multinationals from emerging economies are estimated 21,500 multinationals. After economic crisis, Companies from emerging nations are facing increasing competition in their home marketplaces and are venturing abroad in a bid both to secure resources and to better service foreign demand.
But each of these groups brings strengths to the fight, too. Job creation will no doubt be the cornerstone of any meaningful reversal in the march of foreclosure postings. In November 2009, the national unemployment rate was 10 percent — more than double the 4.7 percent rate in November 2007, according to the U.S. Bureau of Labor Statistics. Jobs are an integral part of the health of the housing market, said Jay Brinkmann, Chief Economist of the Mortgage Bankers Association in a recent report on housing delinquencies. “Over the last year, we have seen the ranks of the unemployed increase by about 5.5 million people, increasing the number of seriously delinquent loans by almost 2 million loans and increasing the rate of new foreclosures from 1.07 percent to 1.42 percent,” he said.
