Nobody lives here: The nearly 5 million Census Blocks with zero population

Nobody lives here: The nearly 5 million Census Blocks with zero population

For many years we have explored Census population maps. It is striking to note this map of zero population areas

"A Block is the smallest area unit used by the U.S. Census Bureau for tabulating statistics. As of the 2010 census, the United States consists of 11,078,300 Census Blocks. Of them, 4,871,270 blocks totaling 4.61 million square kilometers were reported to have no population living inside them. Despite having a population of more than 310 million people, 47 percent of the USA remains unoccupied.

Green shading indicates unoccupied Census Blocks. A single inhabitant is enough to omit a block from shading." from website.
