Current world population (estimated): .
Over the years, precisely the past two thousand years, the population of the world has grown exponentially to hit the 7097869500 as at the 18th of September 2012. Having started at only 200 million, there has been quite a perpetual growth to get to 7 billion.
More than 60% of the world’s population is found in Asia. This owes to the 37% that encompasses China and India’s total population. Africa holds roughly 15% of the world’s population with an estimate of 1 billion people while Europe, with 733 million people, represent 11% of the world population. The Latin America and the Caribbean cover 9% with 600 million inhabitants, Northern America 5% with 352 million and Oceania 0.5% with only 35 million people. It is interesting to note that China is the most populous country in the world, with around 1341335000 people, and Tokyo the most populous city with 35676000. These are more than are found in some continents combined. Following closely is India with a population of 1224614000, then the United States, Indonesia, Brazil, and the list goes on and on.
It is estimated that the world population is currently growing at a rate of 1.3%, with a doubling time of 54 years. In the 1960s, the growth had hit a 2% growth rate and an expected doubling time of 35 years. Evidently, the growth rate of the people in the world has gone down by a considerable margin. However, this does offer no relieve yet because the numbers are still very high. Considering that most, actually almost all, growth takes place in the church-mouse poor countries, especially in Africa and South Asia, it is feared that the planet could become unrecognizable by 2050. It is staggering to note that while the first billion mark was hit after 150000 years, it took barely 12 years to 7 billion compared to the 6 billion of the late 1990s.
Currently, the population of the United States stands at an estimate of 314330846. This makes the United States the third largest population of the world. This represents 4.47% of the world population. The United States population grew by 205 million between the 19th and the 20th century, having been at 75 million in 1900 and 281 million in 2000. Since October 17th 2006, the population of the United States has been 300 million and more and is expected to get to 400million in 2043. The 100 million accumulate with a decreasing number of years. The average annual growth rate of the population of the United States is 0.9%. it is expected to be the third most populous state in the world in 2050, but this time after India and China, in that order, followed by Nigeria.
With the current annual growth rate of 1.3%, the average population roughly changes at 75 million per year. Compared to the 1960s, the growth rate per year is declining. Though uncertain, this rate is expected to keep declining in future. It is projected to be less than 1% by 2020 and no more than 0.5% by 2050. This will be reflected by a growing population but a significantly slower rate when compared with the past years.
It is quite unfortunate that more than 1 billon of the world’s population, lack enough food for them to be healthy and lead a normal active life. Precisely, 1 out of 7 people on Earth are never certain if they will be getting their next meal. This is so alarming. These people are found everywhere, the developed countries included. Asia and the Pacific are particularly notorious for this. Sub – Saharan Africa thou leads with a 33% score. The green population has given the Earth a chance to provide food to all the population in the meantime. However, lack of access to food, very high prices, low incomes and rising levels of unemployment deny the masses a chance to buy food for them.
With the world facing the threat of overpopulation, the earth could soon fail to offer fair grounds for equilibrium or balance, on which life is said to so exist. In the event that there is no more oil and mass production, roughly 1 billion people only can be naturally supported by the earth. Oil deficiency creates the vicious cycle that leads to lack of food necessary for survival, loss of production capabilities and mass transportation and sequential deaths from starvation. A staggering 1 billion people would die within a year. This will soon be inevitable if stringent measures aren’t put in place to control the people of the world.
