I have generated several vector layers of different gradients and geographic areas (PUMAs, ZCTAs & Census Tracts).

Is there a way I can overlay all these layers with the aim of identifying the ultimate hotspots?

Data merge won't do the trick.

  • Have you considered converting them to rasters and applying some map algebra to get the hotspots? That's usually efficient and quicker to compute than vector analysis. – SaultDon Dec 15 '16 at 17:02
