 1. One of five climatically distinct areas, determined according to the 30-year average (1971-2000) of the annual heating and 

cooling degree-days. A household is assigned to a climate zone according to the 30-year average annual degree-days for an 

appropriate nearby weather station.

 Q = Data withheld either because the Relative Standard Error (RSE) was greater than 50 percent or fewer than 10 households

were sampled.

 N = No cases in reporting sample.
