Contrary to common perceptions, jet-setting millennials and wealthy Gen-Xers are far from the only groups to benefit from the coming wealth transfer, according to a recent study.

Over half of the $36.2 trillion projected to change hands over the next three decades will in fact go to low- or middle-income Americans and to households approaching retirement, according to a study from United Income, a RIA indirectly and wholly owned by Capital One Financial.

And 25% of inheritances will go to those over 61 years of age, which indicates “that inheritances may be becoming less about lifestyle enhancement and more about retirement fortification for estate recipients,” United Income says.

The total value of inheritances, meanwhile, has surged 119% over the past 30 years, from $195 billion in 1989 to $427 billion in 2016, when adjusted for inflation, according to the report, which analyzed data from the Federal Reserve on inheritances provided by the silent generation (those born before 1945) to baby boomers (those born between 1946 and 1964) over the past 30 years.

The study’s authors also found that the average age of adults receiving an inheritance rose from 41 in 1989 to 51 in 2016, according to the report.

Meanwhile, the share of households that receive an inheritance has remained remained relatively flat at 20% over the past three decades, United Income says. But the average inheritance has grown by 75% during the same period, from $169,000 in 1989 to $295,000 in 2016, according to the study.
