Nearly 20% of US consumers have experienced ID theft, and younger adults are at greatest risk, the latest Experian-Gallup Personal Credit Index reported. The survey among a nationally representative sample of 1,000+ respondents revealed that 25% of people under age 30 report having their financial information stolen, compared with about 18% of respondents ages 31 to 64, and just 11% of people 65 and older. The poll also finds some significant regional differences. Only 12% and 15% respectively of people in the Midwest and South report being victimized, compared with 20% and 26% of people in East and West.
