A Demographic Question

What do the two shaded regions of Virginia have in common?

Together, they represent half of the states entire population AND each on its own is home to 25% of the state's population.  In other words, the same number of people live in both areas.  So when you see maps colored in red and blue and red covers a larger area, don't assume it means that there are more people living there.  Our democracy is founding in people NOT soil.
