CASE 034 - Population
The Population (as of December 2016) few estimates and bit of info, taken from all around the net
The world population is the population of humans on the planet Earth. It is currently estimated to be 7,497,250,000 by the United States Census Bureau. The world population has experienced continuous growth since the end of the Black Death around the year 1400; the highest rates of growth—increases above 1.8% per year—were seen briefly during the 1950s, then for a longer period during the 1960s and 1970s. The growth rate peaked at 2.2% in 1963, and declined to 1.10% by 2009. Annual births have reduced to 140 million since their peak at 173 million in the late 1990s, and are expected to remain constant, while deaths number 57 million per year and are expected to increase to 90 million per year by 2050. Current projections show a steady decline in the population growth rate, with the population expected to reach between 8 and 10.5 billion between the year 2040 and 2050, but the population has risen from 1 Billion to 6.6 billion from 1890 to 2010 around the time oil production was in full swing, Please read CASE 015 - peak oil.

According to estimates published by the United States Census Bureau, the Earth's population has reached 6.7 billion. In line with population projections, this figure continues to grow at rates that are unprecedented prior to the 20th century. Approximately one fifth of all humans that have existed in the last six thousand years are currently alive. By some estimates, there are now one billion (thousand million) people in the world between the ages of fifteen and twenty-four.
The 20th century saw the biggest increase in the world's population in human history. The following table shows when each billion milestone was met:
1 billion was reached in 1802.
2 billion was reached 125 years later in 1927.
3 billion was reached 34 years later in 1961.
4 billion was reached 13 years later in 1974.
5 billion was reached 13 years later in 1987.
6 billion was reached 12 years later in 1999.
There are 49.65% female (or 3.328 billion females)
There are 50.35% Males
half the worlds population lives in either China or India
Over population is a myth
