It is estimated that 73% of Americans will be among the top 20 percent of earners in the US for at least one year of their lives. This figure was determined by analyzing Internal Revenue Service (IRS) tax data from 1997 through 2007. Although nearly three-fourths of Americans will have household income in the top 20% at some point, those earning rates are constantly changing; only 2% will maintain that status for at least 10 years. This shifting of earnings in US households is thought to be caused by factors such as earning bonuses, changing jobs, leaving the workforce and business performance.
