Spatial Weights Matrix

I am trying to generate a spatial weights matrix with individual level data.  However, none of the default options (to my knowledge) correctly capture the conception of a neighborhood that I am trying to use.  Specifically, I'd like to define each individual's neighborhood as their census tract (all individuals within each observation's tract gets a 1, all individuals not in the observation's tract get a zero--though it would be nice to also approximate the matrix using inverse distance, with a distance band equal to the tract boundary).  I have a separate shapefile with the tract boundaries, as well as a column in my attribute table for the individual level data specifying the tract that each observation is in. 

Is there a way to do this?
