For each counties in the metro area, it gives an estimate of the
population on Jan. 1, 2000, and the percent change between 1/1/2000
and 1/1/2010. If we assume that the percent change for each county
is constant, then the population of each county can be modeled
using an exponential function with a growth rate given by the
annual percentage change.
