1Excludes Alaska and Hawaii. Notes:  ·  Degree-days are relative measurements of outdoor air temperature.  Cooling degree-days are deviations above the mean daily temperature of 65° F.  For example, a weather station recording a mean daily temperature of 78° F would report 13 cooling degree-days.  ·  Temperature information recorded by weather stations is used to calculate State-wide degree-day averages based on resident State population.  Beginning in 2002, data are weighted by the 2000 population.  The population-weighted State figures are aggregated into Census divisions and the national average.  ·  See Appendix C for Census divisions. 2Based on calculations of data from 1971 through 2000.
