Population Growth In The 19th Century

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.

2,000 years ago the world, in terms of population, was only the size of the United States of America, 300 million people. Today, the world’s population is at seven billion and counting. If the population rose at a steady rate from year 0, we would’ve reached 1 billion people by about 210 A.D. This, however, was not the case. We reached 1 billion people in 1800 A.D, which means that there had to be very odd growth periods for the population as a whole REWORD ME. From 0 to 1000 A.D. the population only rose about 10 million people, “and well into the second millennium, [the population] grew less than 0.1 percent each year” [1]. However, from the year 1800, with 1 billion people worldwide, to 1930, the world gained another billion people. We then reached three billion people in 1960, five billion in 1987, and 7 billion in 2013. One can clearly see that once we entered the 19th century, the world’s population started growing like a 14 year old boy going through puberty; rapidly, and without any warning. One thing that can explain this growth is called the Demographic Transition.The Demographic Transition is a theory that explains the growth.

During the eighteenth and early nineteenth centuries the European population grew immensely (Doc. 1). This was because there were lower death rates and more opportunities during this period. Also, one could also observe that the population increased the most in the countries that were being industrialized. Europe experienced tremendous population growth, but it was often decreased with plagues, wars, and famine. Food prices rose because there was a great need to feed the steadily increasing European population. This change fueled both the Agricultural and Industrial Revolutions. With more job opportunities, the European people took advantage of having multiple children because now they could provide more for their family. These fundamental

The human population rate has changed throughout the ages. By looking at the table we were given the human population has increased heaps from 2000 years ago. If we look at our ancestors they lived with a small existence but this has changed as we have developed and there is more agriculture in this world. Population grew very slowly in the 1000 A.D. also decreased after the Black Death causing large numbers of people wiped out. Then in the 1800 A.D. the industrial revolution came, soon living standards were raised and there was food shortage with the population. In 1927 medicine was introduced this meant that there was increased life expectancy, so the human population grew more. There was more advantages from agriculture, medicine and sanitation

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

increase in population due to food, there was a huge decline in population due to diseases like

As the human race continues to grow older the population starts to grow. Population growth is a change in the size of a population over time, depending on the balance of births and deaths over a period of time. For the world, population grows when the amount of births exceeds the amount of deaths. As shown in figure 1, the world’s population grew very slowly until about 1750 that is when the population growth started to increase rapidly. Figure 2 shows the growth of the global population from 1950 onwards, it also shows the projected population growth up to 2050. The global population is estimated to rise to approximately 9 billion people by 2050.

During 1680 to 1750 there was a tremendous population boom in North America. The factors that lead to an increase in population included; higher birthrates, healthier environment, and a reliance on free labor.

Populace has been seen to change throughout the years. In the years of 1900 and 2000 there was an expansion in world populace which was three times more noteworthy than the whole past history. It was an expansion from 1.5 billion to 6.1 billion which is a 4.6 increment in just shy of 100 years.

According text one, Population Trends between the years 1700, to an estimated 2100 as the years go on, the global population size continues its rise. For example, in the data it can be seen that the global population went from .68 billion individuals in 1700, to a predicted 9.46 billion by 2100. Also, the life expectancy increased from 27 years in 1700, to a predicted 81 years by 2100. (Ronald Lee,

Human population of the world is has increased by the billions, in part to economic growth. Not only Europeans in Western Countries and Japan thriving, Asia has been at the top of the growth charts with India and China gaining just

In fact, from 1850 – 1914, over 40 million people left Europe (Easterlin 331), and so migration was presented to have been a reason for population decline. This leads us to decide that one of the determinants of the rates of population growth were fertility and mortality.

Doubling time is the length of time it takes for a population to double in size. Earth’s human population has seen decreasing double times over the last millennium as a result of human exponential growth. Starting from the year 1171, it took 544 years to double our population from 375 million to 750 million. Afterward, it took 166 years to double our population to 1.5 billion people. Next, it took 79 years to double to 3 billion and then only 39 years to double once more to 6 billion people on Earth by 1999.¹ The onset of the Industrial Revolution and advances in agriculture and medicine have all made profound contributions to the human exponential population growth by reducing the environmental and resource limitations that previously kept our population growth in check.

As of 2016, the current global population is 7.3 billion people. At the current rate of growth, the global population is anticipated to be approximately 9.7 billion people by 2050. In addition, this population is anticipated to eat more of a middle class diet. Which means more meat, grains, and protein in a person’s daily diet.

We got to where we are now through a number of civilizations and society-shaping "events", most notably the agricultural revolution, the scientific revolution, and the industrial revolution. By 1980, there were 4 billion of us on the planet. Just 10 years later, in 1990, there were 5 billion of us. By this point, initial signs of the consequences of our growth were starting to show. Not the least of these
