Pew? Phew!
On April 3rd the Pew Internet and American Life Project issued a new report claiming that more than 6 million U.S. adults have listened to podcasts and that 29% of MP3 player owners have downloaded Podcasts.
Pew felt compelled to issue a comment three days later proclaiming "We Stand by Our Data", responding to press criticism of the report's findings and conclusions.
Given that Apple sold a phenomenal 5.3 million iPods in the first quarter of 2005, generating more than $1 billion in revenue, and that total MP3 player sales probably totaled about 8 million for the quarter (extrapolated from iPods constituting about two-thirds of the hardware market), there's little doubt that the installed base for Podcast portability is growing at a dizzying pace.
But a detailed review of the report's findings does raise some reliability questions. For example, it holds that minorities (African-Americans and English-speaking Latinos) are more likely than non-Latino whites to own MP3 players by a ratio of nearly 2 to 1 (16% versus 9%), but then separately finds that "iPods/MP3 players are gadgets for the upscale", with ownership rates of 18% in $75,000+ households but less than 10% in households with incomes below $50,000. Given that minority households have lower average incomes these findings seem at odds.
Similarly, it finds that men are more likely than women to have MP3 players (13% versus 9%). But when one reads the report's Methodology section, one discovers that "In each contacted household, interviewers asked to speak with the youngest male currently at home. If no male was available, interviewers asked to speak with the oldest female at home." Well, if a household is called and the interviewer finds that Billy is too busy playing XBox Live to be interrupted, and then asks for Mom instead of Susie (who's on her computer busily downloading), wouldn't that tend to produce the reported result?
It is almost surely true that Podcasting is a rapidly growing activity. But this report is a good reminder that whenever one sees a headline trumpeting the findings of some new study it is always prudent to review the document to assess its veracity.
