Interesting world population youtube videos
1) World Population, https://www.youtube.com/watch?v=khFjdmp9sZk, 5 min. 46 secs, published by Population Education on Mar 26, 2015
Description: Watch human population grow from 1 CE to present and see projected growth in under six minutes. One dot = 1 million people.
Ravi: I don't know how accurate the data is. Presuming the data (including past population estimates) is reasonably accurate I think it is a fascinating video showing how human population has clustered in certain areas and then exploded into huge growth, over a period of two millenniums.
2) The World in 2015: Global population and the changing shape of world demographics, https://www.youtube.com/watch?v=QwfH1gYkXTw, 4 min 15 secs, published by The Economist dated Nov. 13, 2014.
Ravi: This video shows with an animated pyramid graph how the world's population was previously having a maximum of young children and that as the ages in the age group increased the relative population size reduced. This created a large base at bottom for very young children, progressively tapering as ages increased in the age groups, creating a pyramid graph. The video voiceover says, "The pyramid was characteristic of human population pretty much since the day organized societies emerged." The video states that this is how it was even as recently as 1970.
But now, due to various factors like lower fertility rates and longer life spans in many parts of the world, there is near equality in population between age groups from the very young to the around 30s and the decline beyond the 30s is lesser as compared to 1970 graph! That is an extraordinary change in age wise demographic breakup of world population!
The video shows a graph of world fertility rate (number of children per woman) from 1970 to 2015. The 1970 figure seems to be around 4.6 which dropped to around 2.6 in 2015. So that's a dramatic shift from a world average point of view from larger families to smaller families.
The video then has a graph of male average life expectancy from 1950 to (projected) 2050, for Europe, China and India. It shows a dramatic increase in male average life expectancy for China and India, and a steady increase for Europe.
In 1970-75 the male average life expectancy in Europe was around 66, in China around 64 and in India around 52. In 2010-15, it was around 72 for Europe, around 74 for China and around 65 for India.
The projection for 2060 makes the population size difference between age groups from very young to around 50 to be quite small, with higher age groups after that also having small reductions in size!! If this projection is close to how it will really be in 2060, what an astonishing change in (world average) human society age-wise composition pattern there would be from most of history till 1970, and 2060!!!
The last part of the video shows an animation of the pyramid graph from 1970 to 2060 (projected). That makes for stunning and astounding viewing of a tectonic change in age-wise composition of human society (world average wise) from what human society has been for perhaps most of history, to what it is becoming now. The voice over says as the animation plays out, "For all of history humans have lived in society dominated (by numbers at least) by children. By 2060 children will be no more numerous than any other age group. The year 2015 is roughly the halfway point in this astounding transformation."
3) Future World Populations (2050), https://www.youtube.com/watch?v=YJjz7LVVl8c, 4 min 6 secs, published by The Daily Conversation on Jun 23, 2015
Ravi: The video actually lists the top 20 countries by population size as per estimates for 2050.
4) World Population, https://www.youtube.com/watch?v=BcXZgqIcAHk, around 2 min, published by a sachin shetty on Jul 7, 2015
Ravi: I find it to be an interesting video but the author is not a noted individual and the video has had only 128 views.
[I thank The Economist and have presumed that they will not have any objections to me sharing a few sentence-transcripts from their youtube video listed in this post, which is freely viewable by all, and does not have any financial profit motive whatsoever.]
