Demographics of the world

The demographic of the world include population density, ethnicity, education level, health measures, economic status, religious affiliations and other aspects of the population.According to the 2014 U.S. Census Bureau, the total population of the World was 7,277,869,200.Its overall population density is 50 people per km² (129.28 per sq. mile), without including Antarctica. Nearly two-thirds of the population lives in Asia and is predominantly urban and suburban, with more than 2.5 billion in the countries of China and India combined. The World's fairly low literacy rate (83.7%) is attributable to impoverished regions. Extremely low literacy rates are concentrated in three regions, the Arab states, South and West Asia, and Sub-Saharan Africa. Christianity, Islam, Hinduism and Buddhism are the four largest religions encompassing a little over 75% of the populace.The world's largest ethnic group is Han Chinese. Although English (5.52%) is spoken by many as a second language, Mandarin Chinese (14.1%) and Spanish (5.85%) are the languages with the highest number of native speakers.Human migration has been shifting toward cities and urban centers, with the urban population jumping from 29% in 1950, to 50.5% in 2005. Working backwards from the United Nations prediction that the world will be 51.3 percent urban by 2010, Dr. Ron Wimberley, Dr. Libby Morris and Dr. Gregory Fulkerson estimated May 23, 2007 to be the first time the urban population outnumbered the rural population in history.China and India are the most populous countries, as the birth rate has consistently dropped in developed countries and until recently remained high in developing countries. Tokyo is the largest urban conglomeration in the world.The total fertility rate of the World is estimated as 2.52 children per woman, which is above the replacement fertility rate of approximately 2.1. However, world population growth is unevenly distributed, going from .91 in Macau, to 7.68 in Niger. The United Nations estimated an annual population increase of 1.14% for the year of 2000.There are approximately 3.38 billion females in the World. The number of males is about 3.41 billion. People under 14 years of age made up over a quarter of the world population (26.3%), and people age 65 and over made up less than one-tenth (7.9%) in 2011.The world population growth is approximately 1.09%The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999.It reached the 2 billion mark in 1927, the 3 billion mark in 1960, 4 billion in 1974, and 5 billion in 1987. Currently, population growth is fastest among low wealth, Third World countries.The UN projects a world population of 9.15 billion in 2050, which is a 32.69% increase from 2010 (6.89 billion).
