The current generation of 18-to-34-year-olds – otherwise known as Millennials — is more likely to be living with their parents than in any other living situation for the first time in 130 years, with Miami having the highest number of young people still at home, according to one study.

Just over 34 percent of Millennials nationwide are still living with their parents, despite the population being considered the most-educated generation in American history, according to a study by the apartment-finding service Adobo. In many of the country’s largest metropolitan areas, the percentage of Millennials who haven’t flown the coup is much higher than the nationwide average.

Miami has the highest percent of Millennials stuck at home, with 45 percent of young people still living with their parents, the study found. The city has a relatively high Millennial unemployment rate of 10 percent and the third highest median rent of any city in the top 10, while having the second lowest average monthly income of $1,875, according to Adobo.

Rents too high

Why are Millennials – who make up one-third of the country’s population – choosing to stay at home? According to Adobo, there may not be much choice in the matter after all.

The study shows that the majority of Millennials living at home are employed; the national unemployment rate for the group is 5.5 percent, according to Adobo. Though the population is largely employed, renting their own place is still out of their means.

Rents in the 16 cities with the highest Millennials-at-home rate are averaging at least double, and sometimes triple, Housing and Urban Development’s threshold for acceptable rent cost, which is 30 percent of a person’s monthly income.

Of the 16 cities in the study, the cheapest rent is in Cleveland, which would still require a renter to spend 71 percent of their income on housing, according to Adobo. Millennials in Miami would have to spend 90 percent of their income on rent. In Atlanta, Baltimore, Boston, Los Angeles, San Bernadino and Washington, D.C., Millennial renters would also have to pay at least 90 percent of their income towards rent.

Wages too low

The study uses the median monthly income of Millennials in each city to determine how much of their income would go towards rent. It turns out that the incomes Millennials are taking home are less than for previous generations of young people, Adobo said. And because it is the most educated generation in history (with 60 percent of Millennials having gone to college), the average college graduate is saddled with $30,000 in student loan debt.

“The problem isn’t just high rent, or just lack of education, or just unemployment, or just low pay. Often, it’s a combination.” Adobo wrote in its study. “For many of these 18-to-34-year-olds, living with parents isn’t simply a lifestyle choice but a necessity brought on by high rent prices and relatively low incomes. It’s not hard to see why moving out isn’t an attractive possibility.”
