Kind of puts the current 7 Billion population in a different light; our time really is pretty short.

I don’t see how both of these assertions can be true at the same time. If the population is growing there has to be more people being born than are dying. This would seem to imply more young people than old people.

Populations in developed countries are getting older due to low birth rates, but the birth rates in under developed countries are VERY high. I think the population is getting younger on a global scale.

Editor: Robert, you are correct that the birth rate in third-world countries is still very high. However world population is still “aging” because, globally, people are living a LOT longer. In some first-world countries, average lifespan is now in the mid-80s, when it was in the 60s no so long ago. The extension of longevity is causing an aging of the world population. Wiki reports: “This happens because of rising life expectancy or declining birth rates. Excepting 18 countries termed ‘demographic outliers’ by the UN[1][2]) this process is taking place in every country and region across the globe. In the entirety of recorded human history, the world has never seen as aged a population as currently exists globally.” And in developed countries the “graying” of the population is more extreme: “Among the countries currently classified by the United Nations as more developed (with a total population of 1.2 billion in 2005), the overall median age rose from 29.0 in 1950 to 37.3 in 2000, and is forecast to rise to 45.5 by 2050.”
