(CNBC) — Even before graduating last month with a finance degree from San Diego State University, Lisa Huckemeyer’s son Tyler landed a job loaded with benefits. The 21-year-old’s new position as an internal auditor comes with a 401(k) plan, phone, gym membership and even a company car, which he uses to drive to work — from his parents’ house every day.

Like many millennials, he moved back home immediately after college, even though he can afford an apartment with a roommate or other type of living situation.

For the first time, more 18- to 34-year-olds live at home with their parents than in any other arrangement, according to a recent study by the Pew Research Center.
