It is constructed from Cumulative File variables VCF0724-VCF0727 by summing the number of "yes" responses, plus 1. All variables must be asked in a given year for this count to be calculated: however, if all vars are asked but all are coded DK/NA (0 in VCF0724-VCF0727), then VCF0728 is coded 0. If at least 1 var is codedwith valid data during a year when all 4 questions are used by NES, then this value is computed. 1. No media 2. 3. 4. 5. All four media 0.
