A college education is often a ticket to the best career opportunities. For most graduates, that means moving to the nation’s biggest metropolitan areas, boosting the intellectual capital that helps those cities thrive. But the patterns vary widely by city and by institution.

The maps below show their movement to 70 big metropolitan areas, as well as the share who move to smaller communities.
