This fascinating graphic from Max Galka and Metrocosm shows the world's population divided evenly in half, with the black areas representing areas with less than 900 people per square mile and the yellow areas representing areas with 900 or more people per square mile. Divided in this way, half of the world's population lives in just one percent of the total land area. Metropolitan areas have become increasingly concentrated in recent years and now more than half of the world lives in them.
What's more, the section below showing South, South East and East Asia represents 46 percent of the world's total population. Within this small window are some of the largest groups of people without access to the Gospel of Jesus. Paradoxically, it also contains some of the newest and largest populations of Christians in the world. It is easy to see why this is such an important region in the Church's mission to bring the Good News about Jesus to the world. It's also easy to see why this mission will increasingly be carried out by Asians.
