It’s official: Millennials are old at heart.

Though they’ve been called “disturbingly different” and “the most unique American generation ever,” a bunch of new research shows that millennials behave similarly to boomers in a number of ways, while Gen X stands out. Here are five.

1. Most boomers and millennials think they’re special
The majority of millennials and boomers say that their age group is “unique and distinct” from other generations; most Gen Xers cannot say the same, according to data from the Pew Research Center.

While boomers and millennials agree that their generations are unique, the reasons they give for this uniqueness are very different: Millennials are most likely to say that technology use is what makes their generation special; boomers, on the other hand, are most likely to say a solid work ethic is what makes them stand out.

2. They think marriage and kids are a big part of the American Dream
Ask boomers and millennials what achieving the American Dream means to them, and they’ll answer a little differently than Gen Xers do, according to data released in April by Bank of the West. More than four in 10 millennials and boomers say that having kids is a big part of the American Dream, compared to just 38% of Gen Xers. The marriage numbers break out similarly, though even fewer Gen Xers (33%) believe this is an essential part of the American Dream.

3. They are/were all about living with their parents — even in their 30s
Though millennials get a lot of flack for living with their parents, boomers did it too at their age. Older millennials (ages 28-32) are 2.7 times more likely to live with their parents than people 33-55, according to data released in April by Trulia.com. When the baby boomers — many of whom now have millennial kids living with them — were 28-32, they were 2.8 times more likely more likely to live with their parents that the 33+ crown was. Meanwhile, Gen Xers were just 2.2 times more likely at that age.

4. They’re happy with their jobs
Boomers and millennials are more likely than Gen Xers to say they are happy working at their current company and plan to stay put, according to data from Bank of the West.

This may be because Gen Xers are more likely to be juggling young children and work responsibilities than either boomers or millennials — which studies show can make you less satisfied with your job. Indeed, a separate study from the Transamerica Center for Retirement Studies hints at this as well: While 51% of millennials and 47% of boomers say their employers offer enough promotions, work arrangements and other perks for employees at every age group to succeed, just 42% of Gen Xers say that.

5. They’re not as “green” as they might like you to think
When it comes to behaving in an environmentally conscious way, Gen X stands out — while millennials and boomers lag behind.
