 1 The 1.0 million households that do not heat their homes are not included in these 

categories. 

 NE = RSE row factor not estimated because RSE's for all statistics in this row are between 

0.0 and 1.0 percent. 

 Q = Data withheld either because the Relative Standard Error (RSE) was greater than 50 

percent or fewer than 10 households were sampled. 

 Notes: • To obtain the RSE percentage for any table cell, multiply the corresponding 

column and row factors. • Because of rounding, data may not sum to totals. • See "Glossary" 

for definition of terms used in this report. • All temperatures listed are in degrees Fahrenheit.
