Younger people, here at least, are more health conscious. They’re way more likely than the older generation to go to the gym.
They’re more frugal, a quarter of their life or more has been lived under austerity. They’re more sensible, more mature, more career minded on average than I was 10 or more years ago. (I’m 31, haved recently worked with a lot of 18-25 year olds).
Buying a CD, which is something I still occasionally do even though I jumped on the MP3 bandwagon before most people, is something that a 20 year old just doesn’t do unless it’s a present for their elderly relative maybe.
Electropop and dubstep were far less mainstream a decade and more ago, now they’re all but the pop status quo. The Neptunes were in a decade ago, mashups were also popular. British guitar bands were enormous, there are still some big ones nowadays of course, but in the mainstream The Libertines et al were a big deal.
The internet was getting more useful but in 2003 you could still be a young person with no meaningful engagement with it. I doubt that’s possible in the west in 2013.
Texting was king, social networks were new. Fashion now, way more women and men dye their hair than a decade ago. Hot pants with leggings weren’t in fashion a decade ago (are they still in fashion? I know these things change.)
Tolerance, awareness and support for homosexuality/transgender etc. is far higher now than a decade ago. In Ireland at least people are more internationalised, the result of mass inward migration and cheaper international travel.
I’d like to think people are less racist than a decade ago but that’s a hard one to call. Certainly the racism that’s borne of people who don’t know anyone of another race must be lessened. People are more pessimistic, people are poorer. Emigration is now a big thing again after over a decade of huge inward migration.
Irish society is now, superfically at least, way more like American and British society as international conglomerates have become more embedded in Irish shopping centres. Trends that start elsewhere in the world catch on quicker here due to the net. There’s way less lag between cinema releases, tv show airings, and general awareness of interesting cultural happenings elsewhere on the planet.
Anime, manga, and comics in general have had a resurgence. From my vantage they were more niche in the early '00s than nowadays.
In 2003, I bought my first mobile phone. In the three years prior to that I hadn’t needed it. In 2013 I miss out on parties, events because I don’t have a facebook account. Nobody texts you to tell you about stuff anymore, they just set up an event page.
