Apparently social scientists have been under-counting the rural population of the world by 50% to 84% for quite a while. Forty percent of the people of Earth live in rural areas, so 50% of that is 20% of the population. At least that much isn't counted on surveys. With 8.2 billion being the official number for the population this year, that means there may be more than 10 to 12 billion people on Earth already.
Democrats may seek to find a way to let those billions move to California in order to win elections.
