World Population Clock: 7 Billion People (2013) World Population: Past, Present, and Future (move and expand the bar at the bottom of the chart to navigate through time) The chart above illustrates how world population has changed throughout history. View the full tabulated data. At the dawn of agriculture, about 8000 B.C., the population of the world was approximately 5 million. A tremendous change occurred with the industrial revolution: whereas it had taken all of human history until around 1800 for world population to reach one billion, the second billion was achieved in only 130 years (1930), the third billion in 30 years (1960), the fourth billion in 15 years (1974), and the fifth billion in only 13 years (1987). During the 20th century alone, the population in the world has grown from 1.65 billion to 6 billion. Wonder how big was the world's population when you were born?

A House of Lords cross-party committee cited figures from the Office for National Statistics which predict a 50% rise in the number of over-65s and a doubling in over-85s between 2010 and 2030. While agreeing that longer life is a "gift" to be welcomed, the committee said that unless the Government acts swiftly, it can be expected to cause "a series of crises" in society and public services. The report called on the Government to publish a white paper before the 2015 General Election setting out how England needs to prepare for an older population. Lord Filkin, chairman of the Lords Committee on Public Service and Demographic Change, said: "The amazing gift of longer life is to be welcomed. "This is not a distant issue; our population is older now and will get more so over the next decade.

Long life geography This section explores how life expectancy varies between different countries and how variations in life expectancy also occur according to income, occupation and gender. Key questions How does life expectancy vary between different countries? How does life expectancy vary between different regions of the UK? How do variations in life expectancy occur according to income, occupation and gender? Key concepts Place Scale Cultural understanding and diversity How does life expectancy vary between different countries? Life expectancy is a human development indicator and is a common measure of a country's level of development. HIV and AIDS have taken their toll in Africa, Asia and even South America, reducing life expectancy in 34 different countries (26 of them in Africa). How does life expectancy vary between different regions of the UK? Average life expectancy in the UK is 77.2 years for men and 81.6 years for women. In the South, the picture is different.
