people born before me.
This is so interesting to me. It really makes you think.
however, at the bottom of the page, it posed some "assumptions" that were necessary in calculating such numbers, which is what we discussed in class, about how they did their research and where they were even coming up with the numbers they were getting and how they can ensure that it is true. The assumptions were as follows:
- All figures regarding the population sizes of the world, regions, and countries - total and disaggregated by age and sex - from 1950 onward are based on UN Population Division. World Population Prospects. The 2010 Revision.
- All figures regarding the proportions of urban and rural population of the world, regions, and countries, as well as population sizes of cities over 750,000 inhabitants, are based on UN Population Division. World Urbanization Prospects. The 2009 Revision.
- World and regional populations before 1950 are based on figures published by the UN Population Division. The World at Six Billion, complemented by additional data points from other sources.
- The computation of the number of people that ever lived on earth is based on the same methodology as Carl Haub. How many people have ever lived on earth ? Population Today 1995 (updated in 2002).However, the results are lower because this spreadsheet uses some population data for intermediate points in time that were not included in Haub's original article. Data from 1950 onward are also different.
- The computation of the number of people that ever lived on earth is based on the same methodology as Carl Haub. How many people have ever lived on earth ? Population Today 1995 (updated in 2002).
- The number of births that occurred on any particular day is a simple average that does not consider seasonal fluctuations of birth rates.
- Male fertility is assumed to be equal to female fertility, shifted forward by 3 years.
- Data on contraceptive prevalence by country are based on UN Population Division. World Contraceptive Use 2010.
- The estimates of species extinction are based on Wilson, Edward O. The diversity of Life, The Belknap Press of Harvard university Press, Cambridge, Mass.1992.
- Maternal mortality data are from WHO/UNICEF/UNFPA/World Bank. Trends in maternal mortality: 1990 to 2008.
- Data on marital status are from UN Population Division. World Marriage Data 2008.
- Thie program only works for people who is younger than 100 years old.
These assumptions would obviously alter the numbers calculated. I think that we will never have enough information to know exactly how many people make up our world population at any one moment.
Everyone should really log on to this webiste, it is really interesting.
people were born before you.
also!!!! I share my birthday (September 6th, 1994) with 364,788 other people.
ReplyDeleteI thought there would be a lot more actually.
So I signed on to this website, gave them my information, and got amazed. I 'm sure years of math went into figuring out the totals of the population in each state, country, and continent, but I'm not too sure that I believe all of this. I personally don't think that the exact number can be calculated of how many people there are in the world today and what 'number child' you were. Like we were saying in class, in India 50 babies are born a minute (is this right? I think this is what I head Linnea saying) but what about the other thousands of babies being born in each country? We as a humans are not nearly as advanced yet to determine even by the second when you or I were born or even when a baby in Buffalo was born vs in Guatemala. There are too many assumptions present... But on the other hand I share my birthday with 365,394 other people.
ReplyDeleteBut wait! What about all the other little humans not being accounted for in third world countries where there is nothing? No water, no electricity, no way to be accounted for? Hmm?? What about them?!
ReplyDeleteI was messing around with the website today and I found some of the website very interesting! They do not let you register on the site if you are over 100 years old! They're are over 300,000 people in the world that are over 100. They're not dead yet so they need to include them as well. I also was messing around with the gender, age, and how many kids you have. It does not let you answer how many kids you have if you are 14 or below. I tried looking up how many people in the world are under the age of 14 and have kids and came up with little results. I found several news stories, but not any specific numbers. They're are more then you think though! I think the low ages of people having children is also contributing to the increase in the worlds population. Dylan also has a good point above.
