According to a recent study from Realtor.com, millennials and Gen Z are “pent up” when it comes to housing — there were 1.6 million fewer households for those between 18 and 44 than expected. This means that around 1.6 million expected Gen Z and millennial households didn’t come together last year, mainly due to a lack of affordable housing. The total housing gap was 3.8 million in 2024, and many younger people are sharing households rather than living alone.
