For sample adults who used sunscreen at least rarely when outside on a warm sunny day for more than one hour (SUN1SNS) and who did not give the exact sun protection factor (SPF) number of the sunscreen used most often (SPFNUM), SPFGNUM reports whether the SPF of the usual sunscreen used was "1-14" or "15-50."

For more information, please see SUN1HR and SPFNUM.


SPFGNUM is completely comparable across survey years.
