“These estimates help manufacturers and marketers better understand the markets that have ‘green’ potential, and help them focus their resources,” said Bruce Wilkinson, Vice President of Media and Communications for Nielsen Claritas. “Additionally, it helps them to plan media campaigns and determine inventory levels for each model, market-by-market.”

The research looked at the national ownership rates of high-mileage vehicles including the Honda Fit, Toyota Prius, Toyota Yaris and Mini Cooper. Using auto registration data from RL Polk and Nielsen’s PRIZM segmentation, the percentage of each segment owning these vehicles was calculated. Individual market potential then was calculated based upon the segment composition of each market.

The top ten was made up primarily of coastal metropolitan area, including Boston (4th), San Diego (5th), Chicago (6th) and Los Angeles (9th), all with populations of over one million. Two exceptions were the relatively small areas of Monterey-Salinas, CA (7th), which has a population of 234,000 and Honolulu, HI (8th), with a population of 442,000.

Places where gas guzzlers still rule the road tended toward the south and Midwest, with the states of West Virginia and Mississippi holding seven of the ten areas that had the lowest rates of green auto ownership.

Hybrid Ads include customized ads, branded promos, vignettes, interstitials, and micro-series where sponsor messaging is combined with program or entertainment content.

Recall refers to the percentage of television viewers who can recall, within 24 hours, a hybrid ad’s sponsor.

A hybrid ad’s “recall score” is the percentage of television viewers who can recall, within 24 hours, the sponsor of a hybrid ad they were exposed to during the normal course of viewing primetime TV on broadcast and major cable networks.

Recall scores are indexed against the mean score for all new hybrid ads during the time period to calculate an ad’s “recall index.”

A recall index of 100 indicates average recall.  A recall index of 279, for example, means that a hybrid ad has proven to be about 2.8 times as memorable as the average new hybrid ad during the four-week time period.
