Nearly half of American households depend on their wireless phones to make most or all of their telephone calls. Thirty eight percent of households have no landline and a further 16 percent make most calls via wireless1. If you are conducting CATI research among the "general population" and are only calling landline households, you are missing a large proportion of the population—enough that you could be drawing incorrect conclusions and lacking the opinion of key constituents. Leading researchers, including the U.S. Bureau of Statistics, Stats Canada, and B.C. Stats are rapidly working to include mobile phone numbers in their research studies. Advanis has incorporated this best practice into CATI surveys as well.
