I have a point layer of 400,000 voter residencies and a point layer of 500 polling places. I am trying to find the average distance it takes voters to get to their polling location. Distance by road would be optimal, but I would settle for as the crow flies as well. I have ArcGIS Basic with Network Analyst. I just got NA last week, so I have no experience with it. I have a related field that can match individual voters to a polling location.
