Summary

DescriptionPopulation-doubling.jpg	English: Graphical presentation of data in 'World Population' article showing number of years taken for World Population to double. Two series are interleaved, one starting from 0.25 billion the other from 0.375 billion. Both the graph and table upon which it is based clearly show the number of years taken for the population to double has been constantly decreasing, although current forecasts for future doubling do not. Each time the population doubles the actual increase is of course very significantly more than for the previous doubling. Español: Representacion gráfica de datos en el artículo 'World Population' que muestran el número de años que le toma a la población mundial duplicarse. Se muestra que el número de años que toma a la población mundial duplicarse ha disminuido monótonamente, aunque algunas estimaciones muestran que en el futuro no sería así. Cada vez que la població se duplica el incremento es mayor a los anteriores.
