I think what he was looking for was to buffer out from a location UNTIL a
certain value is reached....
what is your demographic breakdown? what I mean is it would be nice if
you were a the finest "granularity" which is at the block group level as
opposed to Census Tracts....but regardless of what your granularity is you
can always compute a buffer that bisects these until you meet your
threshold.... not very difficult to do..... I just don't have it coded......

Kent,
Select the points in question, then choose Objects|Buffer... and it will
draw a buffer around the selected points with a given radius. Then, you can
use the Boundary Select Tool to select points within the new buffer polygon.
Hope that helps.
