Gen Z Reorders Adulthood Milestones Due to Housing Costs

The traditional sequence of adulthood milestones, including moving out, entering the workforce, marrying, and having children, is being significantly altered for Generation Z and millennials due to escalating financial pressures, primarily driven by housing costs. In 1975, 45% of Americans aged 25 to 34 had achieved all four of these milestones. By 2024, this figure had fallen to fewer than a quarter of individuals in the same age group, according to Census Bureau data cited by Realtor.com. This shift indicates a fundamental reordering of what constitutes the "American Dream" for younger generations.

Housing costs are identified as a primary driver behind this delay. Joel Berner, senior economist at Realtor.com, states that elevated housing expenses compel young Americans to reside with family or roommates for extended periods. This prolonged dependence on parental households impacts their ability to establish independent lives and pursue other life goals. Previous Realtor.com research indicated that a record 25.2 million adults lived with their parents in 2025, representing nearly one-third of adults under 35. A significant portion of these individuals were employed, suggesting that even stable employment is often insufficient to afford independent housing.

The impact of housing costs is particularly acute in high-cost metropolitan areas. Research from the Urban Institute (UI) reveals that young adults in high-rent metros are more likely to live with their parents compared to those in lower-cost areas, across all income levels. This disparity has widened considerably, with the gap between high- and low-cost markets increasing from almost zero in 2005 to nearly 6 percentage points by 2024. While living at home can be a strategic financial decision for saving, Berner notes that the consequences extend beyond mere housing arrangements, potentially hindering the early formation of partnerships.

Beyond housing, other significant expenses contribute to this financial squeeze. A wedding, for instance, can cost approximately $36,000, while a down payment on a home averages $23,400. Furthermore, childcare expenses can consume substantial portions of household income, often in the double digits. These cumulative costs create a formidable financial barrier, forcing young adults to prioritize or postpone major life events. The traditional progression of achieving financial independence, followed by marriage and family, is being challenged as these significant expenses compete for limited financial resources, leading to a redefinition of adult life stages for a generation.
