## Total area of ArcGIS Intersect output is NOT equal to the smaller input?

I have two polygon inputs that share the same projected coordinate system – one is land cover data, the second is parcel data (of smaller total area). When I execute a standard geoprocessing Intersect, and then recalculate the geometry of the Output’s polygons, the resulting total area of the Output polygons is not equal to the total area of parcel data total area (Output is ~200 acres < the parcel data input). I might anticipate slivers in the original land cover data, but the Output shows that all area is classifiable (no null Land Cover classes). Is this a normal occurrence? Or is there something I can/should do to get these areas to match exactly?

Also, not sure if order matters, but I listed the Land Cover data first, and the Parcel Data second, when adding Intersect inputs.

I’m using ArcGIS 10.x for Desktop.
