More than half of millennials care about how their investments affect society, far more than other generations.

The new survey reinforces the idea that millennials are more passionate about making a difference with their investments than other generations, which has been shown in a number  of recent studies.

The study was conducted for American Century Investments, a Kansas City, Mo., based firm whose majority owner is a medical research institute.

Fifty-four percent of millennials consider their investment’s social impact, meaning its positive impact on society, as an important factor in their decision-making process. This compares to 34 percent of Gen-Xers and 37 percent of baby boomers.

The survey for American Century included a random sample of 1,028 adults. Millennials were defined as those aged 18 to 35; Gen-Xers as those aged 36 to 51, and baby boomers as those aged 52 to 70.

Thirty-one percent of millennials named health care, including disease prevention and cures, as the cause that matters most to them for making impact investments.
