World

The world the planet Earth and all life on it, including human civilization. In the philosophical context of "the world" is the entire physical universe, or an ontological world. In a theological context, in the material world or in the sphere of the profane, in contrast to the celestial, spiritual, transcendent or sacred areas. "Doomsday" scenarios refer to the end of human history, often in a religious context. World history is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present. In terms such as world religion, world language, world government and world war I, the term world suggests international or Intercontinental scope, does not necessarily imply the participation of all parts of the world. The world population is the totality of all human populations at any time, in the same way, the world economy is the sum of all economies or countries, especially in the context of globalization. Terms such as "world Cup", "gross world product", and "flags of the world" implies a set and a combination of all sovereign States.

                                               

Demographics of the world

Demographic indicators of countries of the world include population density, ethnicity, education level, measures of health, economic status, religious affiliations and other aspects of human population. The worlds overall population density is 50 people per km2 129.28 per SQ. mile, with the exception of Antarctica. Almost two-thirds of the worlds population lives in Asia, with more than 2.5 billion in the countries of China and India combined. The literacy rate of the world population has increased dramatically over the last 40 years, from 66.7% in 1979 to 86.3 per cent. This low figure is mainly due to poverty. Lower literacy rate in South Asia, West Asia and Africa South of the Sahara. The worlds largest ethnic group is Han Chinese, with Mandarin is the worlds most spoken language from the point of view of native speakers. Of the worlds population is mostly urban and suburban, and there is a significant migration towards cities and urban centres. The urban population jumped from 29% In 1950 to 55.3% in 2018. Working backwards from the United Nations prediction that the world will be 51.3 percent urban in 2010, Dr. Ron Wimberley, Dr. Libby Morris and Dr. Gregory Fulkerson estimates, 23 may 2007, was for the first time urban population exceeded the rural population in history. China and India are the most populous countries, as the birth rate has steadily decreased in developed countries and, until recently, remained high in developing countries. Tokyo is the largest urban agglomeration in the world. The total fertility rate in the world is estimated at 2.43 2017, the world Bank children per woman, which exceeds the world average replacement fertility rate of approximately 2.33 as of 2003, i.e. the world population is growing. However, the growth of the world population is distributed unevenly, with the total fertility rate comes from 0.83 in Singapore, to 6.49 in Niger. According to estimates of the United Nations, the annual population growth rate was 1.14 percent by the year 2000. The current world population growth is about 1.09%. People under the age of 18 constitute more than a quarter of the population is 29.3%, and people 65 years and older made up less than one-tenth to 7.9% in 2011. The world population more than tripled during the 20th century, about 1.65 billion in 1900 to 5.97 billion in 1999. It reached 2 billion in 1927, 3 billion In 1960, 4 billion in 1974, 5 billion in 1987. Total world population is around 7.7 billion as of December 2018. Currently, population growth is fastest among low wealth, the least developed countries. The UN projects a world population of 9.15 billion in 2050, which is 32.69% of the 6.89 billion in 2010.
