Cleveland Population Decline... Why?

[Helen Zhang]

We all know Cleveland Population is Declining every year. I hear a lot of reasons, but other than jobs as being the main reason, I cannot seem to find other reasons that make it reasonable for the declinning population. 

There are a lot of metros with high unemployment and yet the properties are appreciating greatly (EX: Fresno, CA, Bakersfield, CA). 

With such high unemployment rate in Fresno, you would still be able to see an increase in population. Although I strongly believe in the fact that job will significantly impact the population, but after seeing Fresno as an example, I think jobs are not only source nor the true source of population decline. What do you think the reason that may contribute to the decline population? 

Interesting population graph that I see here: 

Although this is not a great indicator that "population is moving to Columbus", but those curves really made me wonder what is happening. 

To local Clevelanders, tell me what you think of the reason of decline population?
