Millennials with different levels of net worth have their assets distributed in much different ways.

A report by Spectrem Group compared Millennials with a net worth of between $100,000 and $1 million to Millionaire Millennials with a net worth between $1 million and $5 million. The net worth calculation did not include their primary residence, although it was included when assessing the proportion it represented of the overall portfolio.

Investable assets represent 42 percent of the total assets of a Millionaire Millennial compared to just 33 percent of the total assets of non-Millionaire Millennials. Also, Millionaire Millennials held 10 percent of their total assets in investment real estate compared to just 4 percent of other Millennials.

The principal residence made up 5 percent of the total assets of Millionaire Millennials but represented 16 percent of the assets of those with less total wealth.

There was a significant difference in the amount of privately held businesses as part of the total portfolio.  Twenty-eight percent of Millionaire Millennials included privately held businesses compared to 19 percent of non-Millionaires.

The two wealth segments flipped each other in how their assets were held. Twenty-seven percent of the assets of Millennial Millionaires are in a professionally managed account, compared to just 19 percent of the assets of non-Millionaires. On the flip side, just 12 percent of the assets of Millionaire Millennials are held in cash or deposit accounts compared to 19 percent of the assets of non-Millionaires.

The report showed a great difference in the attitudes Millennials had about the work of investing. Fifty-eight percent of Millionaire Millennials said they like to be actively involved in the day-to-day management of their investments, while only 43 percent of Millennials with a net worth under $1 million had the same interest
