Averaging Census Tracts and their Demographics into Thiessen Polygons

[orrlydia]

Hello!

I am creating catchment zones based on points. I want to know the demographics of the catchment zones. Right now I have two shape files - one with the Census tracts and all of the demographic data and another with Thiessen polygons around points to create the catchment zones.

 The grey-ish lines are tract polygons and the blue-ish lines are my catchment zones. I need the average of all tracts within the catchment zone. I have tried Spatial Join, but end up with missing data. Also tried to use sf in R, but it does read in the full attribute table, so the demographics aren't there. 

Any thoughts are helpful!
