How do I map counties on both sides of the Delaware River?
Use the national county editor for one map that spans New Jersey and Pennsylvania, and join the values using their full five-digit GEOIDs.
Where do I find the county for Newark?
Use Essex County, GEOID 34013, for estimates that cover the whole county. Newark city observations have a different boundary.

What does New Jersey’s rent-burden map exclude?
