major universities in my market

[Jason Malabute]

I am trying to determine the "economic anchor" of my market. An economic anchor is something that supports the local economy and is not going anywhere even during an economic downturn.

Question: How many students have to be enrolled in a university for that university to be considered an economic anchor? Or is there another factor (besides proximity) that needs to be considered before a university can be considered a major university and economic anchor?

Thank you,

Jason
