does the majority of the world's population live in cities
Megacity In 1800, only 3% of the world's population lived in cities, a figure that rose to 47% by the end of the twentieth century. In 1950, there were 83 cities with populations exceeding one million; by 2007, this number had risen to 468.[24] The UN forecasts that today's urban population of 3.2 billion will rise to nearly 5 billion by 2030, when three out of five people will live in cities.[25] This increase will be most dramatic on the least-urbanized continents, Asia and Africa. Surveys and projections indicate that all urban growth over the next 25 years will be in developing countries.[26] One billion people, almost one-seventh of the world's population, now live in shanty towns.[27] In many poor countries overpopulated slums exhibit high rates of disease due to unsanitary conditions, malnutrition, and lack of basic health care.[28] By 2030, over 2 billion people in the world will be living in slums.[29] Over 90% of the urban population of Ethiopia, Malawi and Uganda, three of the world's most rural countries, already live in slums.
Demography of the United States The United States is estimated to have a population of 327,589,916 as of April 23, 2018, making it the third most populous country in the world.[3] It is very urbanized, with 81% residing in cities and suburbs as of 2014 (the worldwide urban rate is 54%).[4] California and Texas are the most populous states, as the mean center of U.S. population has consistently shifted westward and southward.[5][6] New York City is the most populous city in the United States.[7]
