While getting its graphics’ proportions right this time around, research firm Nielsen revealed July 2012 findings today and announced 55.5-percent of mobile subscribers in the United States now own smartphones with young adults and teenagers leading the charge.

According to the Nielsen blog: 

Android still dominates the smartphone OS market in terms of owners and recent acquirers, but iOS maintains second place with 34 percent of smartphone owners and 33 percent of recent acquirers.

Overall, young adults are leading the growth in smartphone ownership in the U.S., with 74 percent of 25-34 year-olds now owning smartphones, up from 59 percent in July 2011. Interestingly, teenagers between 13 and17 years old demonstrated the most dramatic increases in smartphone adoption, with the majority of American teens (58%) owning a smartphone, compared to roughly a third (36%) of teens saying they owned a smartphone just a year ago.

Nielsen’s monthly survey is conducted across 20,000 mobile subscribers from the ages of 13 and up in the U.S.
