Ap World Population Chapter 1 Summary

The world population of 7.2 billion in mid-2013 is projected to increase by almost one billion people within the next twelve years. It is projected to reach 8.1 billion in 2025, and to further increase to 9.6 billion in 2050 and 10.9 billion by 2100. This assumes a decline of fertility for countries where large families are still prevalent as well as a slight increase of fertility in several countries with fewer than two children per woman on average.

Major progress has been made in curbing population growth. The United Nations Population facts August 2010 states that there has been substantial declines in fertility, total fertility in the rest of the developing world(excluding the least developed countries) declined by about 50 per cent between 1970-1975 and 2005-2010: from 5.0 to 2.5 children per woman. Additionally fertility in the least developed countries dropped by 34 per cent since 1970-1975, from 6.7 to 4.4 children per woman. Bangladesh is exceptional with a reduction of over 60 per cent, from 6.9 children per woman in 1970-1975 to an estimated 2.4 in 2005-2010.

Between 1400 and 1700, the global residents rose slightly from 300 million to about 1,2 billion people but then this figure dropped marginally to just under 1 billion humans. After a decline of 300 million people, the number of this grew sharply by nearly 5 billion, to exactly 6 billion people worldwide at the end of the examined period.

Scholars estimated that population of the world was around 10,000 people 100,000 years ago and slowly inclined to a population of 500,000 people 30,000 years

There was clearly 3. 99 million children thought inside US. Inside 2014, upward coming from 3. 93 million new child young children considered inside US. Inside 2013 a great off shoot of about 1 percent, as showed from the

billion in 1900 to over 6 billion in the year 2000 (Haugen, sec.2). This expediential population

“Overpopulation is an undesirable condition where the number of existing human population exceeds the carrying capacity of Earth. Overpopulation is caused by number of factors. Reduced mortality rate, better medical facilities, depletion of precious resources are few of the causes which results in overpopulation.” In today’s society most Americans have at least five children, this can include one person who has five kids that was from failed relationships, marriage, or mistakes. The amount of children that are born per year in the U.S is 3,999,386 last year alone. The U.S alone has over three hundred million people, making us the third largest nations. The U.s is the only population that is experiencing significant population growth. Its population may double before the end of the century. If the limitation of how much children each American can have decrease to two children then we can put a control on overpopulation.

Since our origin, worldwide human population has steadily been on the rise. We humans emerged as a species about 200,000 years ago. In geological time, that is really incredibly recent. Just 10,000 years ago, there were one million of us. By 1800, just over 200 years ago, there were 1 billion of us. By 1960, 50 years ago, there were 3 billion of us. There are now over 7 billion of us. By 2050, your children, or your children 's children, will be living on a planet with at least 9 billion other people. During some time towards the end of this century, there will be at least 10 billion of us.

According to Meder & Windelspecht (2014) the human population was approximately five billion people in the 1650’s, and by the 1850’s is doubled again. Now today we are estimated to have approximately seven billion people

Since 1914, global population has increased dramatically. Before 1914, there had been about 90 billion people ever born. Since then, the approximate number of people ever born has increased to 100 billion. Life was very short for the first 90 billion people and until World War I, the death rates and birth rates were neck to neck. Eberstadt (2014) believes that the number of humans born over the course of 50,000 years before the 1900’s could not have possibly grown by more than three one hundredths of one percent on average per century. The recurrent disappearance of nations and sometimes even entire civilizations enforced “population balance” for most of history. Around 1900, the human population was at around 1.5 billion and over the course

The average child rate in the world is currently 2.2 children per women. This means that every family is having an average of two children. In countries that have more than 2 children

Population growth is a problem to the Asian populations health, economy and poverty issues. The one child per family method is an option like what China implemented. Method like birth control programs are also a way to figure out population growth issues. One method that china used in the 1980s was to tell the people that increasing economic growth would help hinder population growth. I dont see how explaining the harms of over population to the public wouldn't be enough for the public to help fix this problem. Spreading awareness about contraceptives and not having such young marriages are also ways to help with this problem.

Population around the world is rising hastily, so fast that the world’s population has just reached

Halifax, Nova Scotia. An estimate of the total population by census for 2011 was 390,090. The approximate number of population in the year of 2013 was 409,000. The forecast for 2014 is 410,000. (Greater Halifax Partnership, 2014)

There are more than seven billion people on Earth now, and about one in eight of us don’t have enough food to eat. So, with a projected nine billion people by the year 2050, how many people can the Earth support while maintaining a healthy population? Population changes are due to the relationship between births and deaths. If the number of births equals the number of deaths then the world’s population will remain the same, but if births exceed deaths, population growth will occur. Early in history, population was slowly growing because of high death rates related to wars, famines, and poor medical services. With advances in
