World population

i wanted to take a closer look at population data to figure out approximately how much population is increasing each year, by percent growth.

i found this; http://en.wikipedia.org/wiki/World_population_estimates and i started to wonder why the United States Census Bureau seems to have the most population data. i mean, i would suspect other countries have also been keeping a close eye on world population, in addition to their own growth.

countries like China who had actually taken plans to control population. i bet they have a lot of research on this. maybe they don’t share their data, i don’t know, but it seems odd that the US would be the leader on world population data. i find it curious, and i’m too lazy to find something other than wiki, so… we’ll use what’s there.

the first figure we have from the US is 2,555,974,605 people worldwide, in 1950. in the next 5 years, the population grows by 224,948,488 or 8.8% or 44,989,697.6 per year.

1955: 44,989,697.61960: 52,154,935, + 15.9263%

1962: 48,612,147, - 6.7928%

1965: 70,121,756.66, +44.2474%

1966: 70,440,885, + 0.4551%

1970: 73,058,361.75, + 3.7158%

1973: 76,529,777.33. + 4.7516%

1975: 73,530,295, - 3.9194%

1980: 72,787,187.2, - 1.0106%

1985: 79,900,883.6, + 9.7733%

1990: 86,327,097.8, + 8.0427%

1995: 82,597,862, - 4.3199%

1998: 78,471,404, - 4.9958%

1999: 76,163,844, - 2.9406%

2000: 75,295,425, - 1.1402%

2001: 75,692,290, + 0.5270%

2002: 75,119,261, - 0.7570%

2005: 74,027,103, - 1.4539%

2006: 74,541,551, + 0.6949%

2007: 75,230,155, + 0.9238%

2008: 74,897,743, - 0.4418%

2009: 74,874,710, - 0.0308%

2010: 74,599,746, - 0.3672%

there’s an increase of 20 million people per year from 1962 - 1965 people started fucking a lot more, i guess, or we cured something that was leveling the birth:death ratio

so… i didn’t really know where i was going, when crunching these numbers, other than to get a better feel for the population growth of the world.

looking at the results from the data i was able to get from the wikipedia entry, the last few years seem … dangerously optimistic, the growth doesn’t fit, considering larger population means more births.

the data not from the census bureau didn’t quite agree, but there wasn’t enough other data there, to look at trends.

long story short; we’re adding about 75 million people to this planet, EACH year.

since 1955, population growth in the world has increased by 65.8152%

the figures, as crunched, indicate that the growth is levelled off, but we’re still gaining a net 75 million bodies on this planet, each year. unless growth goes down, we may be in trouble.
