By integrating the same data sources used to comply and report on the ACA — HRIS, benefits and payroll — new insights can be gained. Analyses shared within the Health e(fx) 2018 Insights Report reveal some unique findings on the benefit preferences shown by different generations.

For example, millennials and Gen Z are less likely to enroll in employer-sponsored coverage than employees from older generations. And when they enroll, millennials and Gen Z workers are more likely to choose benefits with a lower actuarial value, meaning the benefits are cheaper but will also cover a lower percentage of their medical costs. However, as these two generations age, they will impact your budget through:

1. Increased enrollment

Currently, 35 percent of Gen Z and 77 percent of millennial employees are ACA eligible for benefits. Of those, only 26 percent of eligible Gen Z employees and 68 percent of millennials are enrolling in employer-sponsored coverage. There are multiple factors that could be impacting this lower enrollment. Due to their stage of life, these younger generation employees are less likely to face significant or chronic health challenges. Because some millennials and most Gen Z employees are still eligible to be covered under a parents' health insurance plan, many are not yet enrolling in their own employer-sponsored benefits. But in the next five years, nearly 1 in 5 employees enrolled in family health coverage will have a millennial or Gen Z dependent age out of parental coverage.

2. Choosing better benefits

Every health insurance plan is assigned a metal level—Bronze, Silver, Gold or Platinum—based on actuarial value (percent of covered medical costs that a plan will pay). Plans with a higher actuarial value (such as Gold and Platinum) pay a higher percent of medical costs, but their premium costs are also higher. A higher percent of employees in these two younger generations select a Bronze-level plan (with the lowest actuarial value) than workers in other generations. In fact, 27 percent of Gen Z and 16 percent of Millennials are enrolled in a Bronze plan, compared to 12 percent of Gen X or 10 percent of late boomers. This means that currently, these younger employees are more likely to have lower premiums for their coverage.

3. Increased family tier coverage

Both younger generations have lower enrollment in family tier coverage, with only 30 percent of eligible millennials and 6 percent of Gen Z enrolled in family coverage, versus 55 percent of Gen X. As the younger generations age, more employees in these generations will opt for family coverage.

Why do these factors matter? Because benefits impact retention. But only if your clients' employees enroll to take advantage of those benefits. According to our analysis, the average overall tenure for employees who are not enrolled in health benefits is 3.1 years, versus 6.7 years for those enrolled in employee-only coverage and 9.7 years for those enrolled in family coverage. On average, length of tenure also increases with better benefits—as the actuarial value of benefits increase, so does tenure.

As these generations age, benefits brokers and employers will have to revisit their benefits strategies to ensure they're offering quality and affordable coverage to keep these generations invested in staying in one place. These younger employees are more likely than previous generations to change jobs in an attempt to achieve the wage and benefits that would enable them to live the lifestyle they desire. With the younger generations soon dominating the workforce, their increased enrollment and transition to better benefits and family coverage may impact your client's budget, and the longevity of their workforce.
