for those of us who do research in linking the online (social media) and offline worlds, it is very important to keep in mind the demographics of different social media services.
In Sept 09, according to Nielsen Claritas , “the blogging and tweeting community at large isn’t necessarily more affluent, but bloggers and tweeters do live in more urban areas such as New York, Los Angeles, San Francisco, and Chicago.”
african american were more likely to join twitter than other racial groups. hargiatti&litt found out why that was the case, and they did so upon analysing *longitudinal* data (i.e., user cialis 100mg data in 2009 and service (twitter) adoption in 2010). the predictors of twitter adoption in 2010 were:
1) be african american
web skills (as for 2009)
3) interest in (as for 2009): entertainment/celebrity news (this topic entirely explained the higher level of adoption for african american); science&research&technology&politics&news (negatively correlated. warning: these topics were negatively correlated for the age group under study – which was college students in chicago; for an older cohort, these topics might well matter).
- London’s Latin American population rises fourfold
- The changing demographic profile of Twitter users in the UK, with its user base starting to look much more like the average UK internet user
- Smartphone penetration among young people in lowest income bracket > older people in wealthiest bracket - http://t.co/sUT59QGe
- Twitter now has 10m users in UK, with 80% accessing it with mobile phones
- Digital participation is now the norm rather than the exception: 77% of UK population
In UK, we badly need research similar to hargiatti&litt’s. Until now, I only heard people complaining about data being not representative, but nothing has been done to partly tackle the problem
