Taking Aim with Consumer Cellular Sample

How Consumer Cellular Sample Can Give You a More Accurate Geographic Fit of your Target Population and Improve Coverage

Geo-targeting. We all know what it means, but for the sake of this article, let’s get at the essence of the concept. Geo-targeting is a way to pinpoint an audience based on location. Accuracy is everything. Geography is the fundamental basis for every sample frame – be it individual streets, Census geography or Postal geography.

Certain sample frames such as Cellular RDD tend to be difficult to target geographically due to inward and outward migration of individuals who retain their cell phone numbers.  It’s important to be aware of these limitations when using a Cellular RDD sample, especially when targeting small geographies.

Here’s how you can miss the target: a cellular RDD sample will include people who have moved outside your target geography (a.k.a. outward migration). Additionally, respondents might live in the area of interest, but do not have an opportunity to be included in the RDD frame (inward migration). They have a cell number that corresponds to an entirely different geography. These people wouldn’t  be included in a traditional cellular RDD frame. The result? Under-coverage due to inward migration and increased data collection costs due to outward migration

So how can we account for the under-coverage and take better aim? One option is to supplement from a relatively new convenience frame called Consumer Cell. This frame is based on a multi-source model comprised of consumer databases linked to publically available cellular telephone numbers. It is updated monthly.

The Consumer Cell  database is built from literally hundreds of sources including

  • Public records
  • Census data
  • Consumer surveys
  • Telephone directories
  • Real estate information (deed & tax assessor)
  • Voter registration
  • Magazine subscription
  • Surveys responses
  • E-commerce
  • Proprietary sources

Geographic targeting using consumer cell can be highly accurate, zooming in on small geographies such as census blocks or even the household level.  Further stratification can be done for numerous person and household level demographic variables.

One limitation to the database is that it is a convenience frame (non-probability compilation of households). It does not offer the same coverage as an RDD frame. It is probably best utilized as a supplement to sample respondents who live in a targeted geography. One of the benefits is that you now include respondents who otherwise would not have been sampled.

If your area of interest is at the state or local level, you should consider where we can address under-coverage issues with RDD cell sample.

TCPA Compliance

My name is Tim Antoniewicz and I am not a lawyer.  I am not legal counsel.  I once played Clarence Darrow in a junior High School production of Inherit the Wind but what I am about to say should in no way be considered legal advice.  However it may be considered helpful in sorting out the quandary that many researchers face when conducting research with a cellular sample frame.

In light of the new FCC regulations (6/18/15) that expand the TCPA, CASRO has provided the following guidelines:

The Federal Communications Commission approved new regulations that expand the Telephone Consumer Protection Act (TCPA). The new FCC rules broaden restrictions on autodialed calls to cell phones without differentiation for caller intent. 

ALL calls to cell phones made using an auto-dialer are PROHIBITED.

DO:

ALL calls to cell phones should be manually dialed.

Regularly update number databases to identify numbers ported to cell phones.

Don’t:

Use a predictive dialer OR an auto-dialer to call cell phone numbers.

Assume that human proximity to, or intervention in, the placement of an autodialed call to a cell phone provides exemption from the TCPA.

Staying educated and taking proactive measures are the key to compliance with the law. Here are some high-level guidelines to follow:

  • Mitigate the risk by verifying the types of phones numbers on your list
  • Get the consent of the current wireless subscribers to a number
  • Be aware of ethical considerations including respondent safety and privacy.

Marketing Systems Group can assist you in flagging likely wireless numbers, identifying ported landline-to-wireless numbers and real-time screening of active cell phone numbers.

MSG is committed to helping you navigate the ever changing regulation landscape from the TCPA and remain in compliance while accomplishing your research goals.
