Is it getting a little crowded here? It’s not just you; the world could get a little more crowded by October 31st. The U.N.’s Population Fund predicts that the human race will reach the 7 billion mark by the end of the month sharing the Earth’s land and resources.

With at least 250 babies born in the world every minute, the world is indeed getting a little smaller. China and India are already the two most populous countries in the world. The U.S. is now the 3rd with the now 312 million people calling the States home, however, our growth is linked more to immigration than birthrates.

The human population has been growing exponentially and more rapidly since first hitting 1 billion in 1804. It wasn’t for another 123 years before we hit 2 billion in 1927. That when the population began to surge — blowing past 3 billion in 1959, 4 billion in 1974, 5 billion in 1987, and the most recent milestone of 6 billion in 1998.

Contributing factors towards the exponential rate of population growth is higher birthrates, lower infant mortality rates and longer life expectancy. As medicine has improved over the last century, more babies are living longer and can expect to live an average of 69 years, which is up from the 48 years in 1950.

The U.N. projects that the Earth will see 8 billion humans walking the planet by 2025 and possibly 9 billion by 2083.
