  • Population Density

    1. 1. WORLD Population Clock 6,809,071,631 17:31 UTC (EST+5) Mar 17, 2010
    2. 2. Estimated resident population of New Zealand as at Thursday, 18 Mar 2010 at 06:26:31 am 4,359,249
    3. 3. 2009 World Population (Aug. 12, 2009) Global population numbers are on track to reach 7 billion in 2011, just 12 years after reaching 6 billion in 1999.
    4. 4. Virtually all of the growth is in developing countries. And the growth of the world’s youth population (ages 15 to 24) is shifting into the poorest of those countries.
    5. 5. Paris
    6. 6. Africa's population has just passed 1 billion. The continent's population is growing by about 24 million per year, and will double by 2050.
    7. 7. About half the world lives in poverty. Nearly 50 percent of world population lives on less than the equivalent of US$2 per day. Hundreds of millions of people live barely above that level.
    8. 8. Population Density Population density is a measurement of the number of people in an area. It is an average number. Population density is calculated by dividing the number of people by area.
    9. 9. Population density is usually shown as the number of people per square kilometre. This map is a choropleth (shading) map and illustrates population density. The darker the colour the greater the population density. The map shows that world population distribution is uneven. Some areas have a high population density while others have a low population density. Areas of high population density tend to be located between 20° and 60°N. This area contains a large land area and a relatively temperate climate.
    10. 10. "Population density" is the term that describes the number of individuals occupying an area in relation to the size of that area. The population density is derived by dividing the number of people by the area they occupy. Noah's Ark gets a bit overcrowded.
