As expected, CPO households are markedly younger, according to Scarborough, which found that 50% of CPO respondents fall between the ages of 18 and 34 -- over three times the proportion of this age cohort in landline surveys.
CPO households also showed a larger proportion of ethnic minorities, with incidences of African-Americans, Hispanics and Asians in these households, ranging from 20% to 50% higher than landline households.
Scarborough plans to expand the CPO surveys from the current group of selected markets to cover all 77 of its top-tier local market studies.
The first expansion of local markets with CPO studies (with data to be released in April 2011) includes Los Angeles, Miami, Boston, Dallas, Houston, Las Vegas, San Francisco, New Orleans, Albuquerque, Birmingham, Colorado Springs, El Paso, Greenville, SC, Harlingen/McAllen, TX, Honolulu, Little Rock, Mobile, Nashville, Orlando, Raleigh-Durham, Richmond, San Antonio, Spokane, Tampa and Tucson.
The second expansion (with data to be released in October 2011) includes New York, Chicago, Philadelphia, St. Louis, Washington, D.C., Bakersfield, CA, Buffalo, Cincinnati, Cleveland, Detroit, Ft. Myers, FL, Grand Rapids, Green Bay, Greensboro, NC, Harrisburg, Hartford, Indianapolis, Louisville, Minneapolis-St. Paul, Providence, RI, Roanoke, VA, and West Palm Beach.
