In January 2012 chemical engineering student Emil Johansson published a website with the hope for it to become a complete Middle-Earth genealogy. Now, ten months later, he has published some interesting numbers derived from the database of 923 characters. The site features a set of unique graphs helping us understand the world Tolkien described. Perhaps the most interesting ones are showing the decrease of the longevity of Men and the change in population of Middle-Earth throughout history. The latter was also recently published in the September edition of Wired Magazine.
