Difference in elderly households counts in tables S0103 & B11007?

I'm trying to understand why these two tables would present different counts for 65+ households.

In looking at statistics for Cambridge, Massachusetts:

  • Table B11007 lists 10,013 "households with one or more people 65 years and over"
  • Table S0103 lists 9,248 households in the "65 years and over" field

My best guess would be that table S0103 actually refers to a count of householders who are 65+ y.o., but I can't seem to find the documentation to confirm this. Does anyone have a better understanding of this discrepancy?


Thank you!
