Thanks for your response, Dan! Yes, it's projected in USA_Contiguous_Albers_Equal_Area_Conic. I was just going about it by right clicking on the layer, then hitting join, and spatial joining points to polygons. Is intersect a more reliable way of joining data for finding the census tract ID for each point? It's for the entire USA (92,000 points to 73,000 census tract polygons).
