According to the census bureau,the Cincinnati msa includes 4,800 square miles while the columbus msa is 3,169 square miles,the csa for columbus would be close in area to cincy but larger population.The latest estimates project the current msa areas to be cbus around 2.6 million and cincy 2.3 million in 20 years.Now even if the cincy csa includes the depressed counties of Montgomery and possibly Greene,to the csa,Clark county would be added to columbus csa.and cincy would have a huge less densely populated csa,which would still be smaller than the columbus csa in perhaps the next census.We cannot underestimate the growth and importance of the columbus region to ohio,the demographics also will favor central ohio.
