Boomerang college kids: Unemployment, job mismatch, and co-residence

During COVID-19, around 26 million young adults in the US returned to live with their parents, but this trend started well before the pandemic and is dominated by college graduates. This column explores the role of ‘job mismatch’ – where graduates have jobs that do not require a college degree – in this. The lower earnings from being unemployed or in a mismatched job have a large impact on co-residence, jointly with the rise in student debt burdens and rising rental costs. High schools and universities should be more active in preparing students to navigate the increasingly challenging labour market as young graduates.

During the pandemic, around 26 million young adults in the US returned to live with their parents (Fry et al. 2020). A recent survey suggests that two-thirds of ‘Millennials’ and ‘Generation Z’ who moved back with their parents at the peak of the pandemic still live there, more than two years later (Ceizyk 2022). However, this is a trend that started well before COVID-19.

A 2012 survey found that 39% of 18–34 years olds were living with their parents or had moved back for some time, with young adults outpacing other groups in multigenerational living (Pew Research Center 2012). This trend is dominated by college graduates. Figure 1 shows that, on average, 31% of the 2013 college graduation cohort resided with their parents at age 23 to 27 years old, compared to only 25% for the 1996 graduation cohort.

What is driving the rise in co-residence for young college graduates? The worsening of labour market conditions for college graduates in the last two decades likely contributed. In our recent study (Albanesi et al. 2022), we focus specifically on the rise in ‘job mismatch’, that is, the incidence of college graduates employed in jobs that do not require a college degree. Figure 2 shows that the job mismatch rate for the 2013 graduation cohort at age 23 to 27 years is around 52% on average, which is 7% higher than for the 1996 graduation cohort at the same age.

In addition to the lower availability of suitable jobs, young college graduates also experience a rise in unemployment, as shown in Figure 3. The unemployment rate at ages 23 to 27 years old is 30% higher for the 2013 college graduation cohort compared to the 1996 cohort, increasing from an average of 9% to 12%.

We argue that, faced with an increase in job mismatch and unemployment, young college graduates choose co-residence. This enables them to weather spells of unemployment and low wages in mismatched jobs in the short run and to wait for a ‘matched’ job, eventually leading to higher future earnings. This notion is supported by empirical evidence.

We show that young college graduates who are employed are less likely to co-reside with their parents than those who are unemployed and that those who work at a matched job are less likely to co-reside than those working at a mismatched job. These findings suggest that labour market performance is inversely related to co-residence in the short run.

Additionally, college graduates who at age 23 are either unemployed or working at a mismatched job have monthly earnings that are 17% lower than those working at a matched job by age 27. For those who do not co-reside or move back with their parents at the time of unemployment or mismatched-job spell, earnings at age 27 are 26% lower; in contrast, there is no earning impact on those who co-reside or move back with their parents. Hence, co-residence is estimated to have a strong positive effect on future earnings for young college graduates experiencing adverse labour market conditions.

While this evidence suggests a link between worsening labour market conditions for young college graduates and co-residence, other factors may also have played a role. The fraction of college graduates with education loans increased from 18% for the 1996 graduation cohort to 41% for the 2013 cohort. Average balances among those with student debt went up by $5,000 to more than $25,000 because of increasing college tuition and fees (Narayan et al. 2016). Meanwhile, transfers from parents decreased because of the adverse impact of the 2007–2009 housing crisis and recession on net worth, as can be seen in Figure 4. Rental costs also rose, and wage dispersion increased throughout the labour market, raising the option value of unemployment.

Total debts include student loans and other debts, where other debts include credit card loans and debt on stocks or bonds. Net assets are defined as total assets minus total debts.

To jointly determine the quantitative impact of all these factors on co-residence, we develop a structural model of child-parent decisions, where co-residence status and labour market outcomes for the children are jointly determined as a function of earnings, assets, family characteristics, and preferences. In the model, by deciding to reside with their parents, college graduates can remain unemployed and wait for a matched job rather than accept a mismatched job. If the rate of arrival of matched jobs declines, more college graduates will choose to reside with their parents. We estimate the model using the 2014 Survey of Income and Programme Participation to account for the differences in living arrangements, unemployment, and earnings between the 1996 and 2013 college graduation cohorts.

The model allows us to break down the impact of changes in the matched-job arrival rate, earnings dispersion, student-debt burden, parental income, and rental costs. These factors can jointly explain all the difference in unemployment rates, 54% of the difference in matched job rates, and 68% of the difference in co-residence rates between the 1996 and 2013 college graduation cohorts.

We use the model to assess the relative strength of each of the channels. We find that the decline in the matched-job arrival rate and rise in earnings dispersion have the largest effect on changes in unemployment. The rise in earnings dispersion has a large impact on co-residence, jointly with the rise in student-debt burdens and rising rental costs. We also find that changes in preferences over marriage and household formation are important in shaping the evolution of co-residence behaviour between the two graduation cohorts.

Even with the rise in job mismatch and unemployment for college graduates, college graduates face higher employment rates and lifetime earnings and lower unemployment rates than individuals without a college degree (see, among many others, Card 1999, Mortenson 2001, Harmon et al. 2003). However, not all college graduates are able to reap the benefits of a college education. Given the changes in the landscape, high schools and universities should be more active in helping and preparing students to navigate the increasingly challenging labour market as young college graduates, especially given how knowledge of labour market opportunities can influence students’ choice of major (Marinescu et al. 2017).
