City population and especially area are, however, heavily dependent on the definition of “urban area” used: densities are almost invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, and the surrounding suburbs excluded.
The report foresees the Hispanic or Latino population rising from 16% today to 30% by 2050, the African American percentage barely rising from 19% to 11%, and Asian Americans upping their 6% share to 8%. The United States had a population of 310 million people in October 2010, and is projected to reach 400 million by 2039 and 439 million in 205 It is further projected that 82% of the increase in population from 2005 to 2050 will be due to immigrants and their children.
There were over 156 million women in the United States in 200 The number of men was 154 million. At age 85 and older, there were more than twice as many women as men. People under 20 years of age made up over a quarter of the U.S. population (23%), and people age 65 and over made up one eighth (18%) in 200 The national median age was 38 years.
Vancouver is a city with a population of roughly 1 million people if you include the greater Vancouver suburbs. The downtown core has become less population dense the past few decades, relative to the total population, mainly because it’s a small geographical area surrounded by water, limiting the space available. This means small apartments, and no chance of a yard or land to call your own.
According to our latest research report, “Saudi Arabia Education Forecast to 2013”, the population growth in the country has been averaging between 5% 3% during past few years, which is one of the highest globally. The fast growth in population transformed in increasing number of student enrollments in all education systems, be it elementary, intermediate, secondary or higher education. For instance, during 1993 2008, the number of high school graduates in the Kingdom increased by 443%. The surging penetration of primary education constructed a solid platform for higher education industry developments, and we anticipate that student enrollments in higher education will grow at a CAGR of 17% during 2009 201
David Pimentel, professor of ecology and agriculture at Cornell University, estimates that the sustainable agricultural carrying capacity for the United States is about 200 million people; its population as of 2015 is over 300 million. In 2009, the UK government’s chief scientific advisor, Professor John Beddington, warned that growing populations, falling energy reserves and food shortages would create a “perfect storm” of shortages of food, water, and energy by 203 According to a 2009 report by the United Nations Food and Agriculture Organisation (FAO), the world will have to produce 70% more food by 2050 to feed a projected extra 3 billion people.
In Western Europe the number of vegetarians varies between 2% and 4% of the population according to to a 2006 Mintel survey (Mintel.com), with the United Kingdom as the exception. The UK is shown as having the highest per capita vegetarians in Western Europe at 6% of the population. The large number of vegetarians in the UK is accounted for to some extent by health scares relating to mad cow disease.
In 2000, the United Nations estimated that the world’s population was growing at an annual rate of 14% (equivalent to around 75 million people), down from a peak of 88 million per year in 198 By 2000, there were approximately ten times as many people on Earth as there had been in 170 Globally, the population growth rate has been steadily declining from its peak of 19% in 1963, but growth remains high in Latin America, the Middle East and Sub Saharan Africa.
The world’s population is around 7 billion, and Earth’s total area (including land and water) is 510 million square kilometers (197 million square miles). Therefore, the worldwide human population density is around 7 billion ÷ 510 million = 17 per km2 (35 per sq. mile). If only the Earth’s land area of 150 million km2 (58 million sq. miles) is taken into account, then human population density increases to 47 per km2 (120 per sq. mile). This includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 50 people per km2 (over 130 per sq. mile). However over half of the Earth’s land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, and population tends to cluster around seaports and fresh water sources. Thus this number by itself does not give any helpful measurement of human population density.
