What is Aged 60+?
Aged 60+ measures the share of your active employees who have reached age 60. It is one of the most practical workforce demographic metrics in people analytics because it answers a question every CEO and CFO eventually asks: how much of our workforce is about to retire?
The metric lives inside a broader family of age-distribution measures: average age, median age, age pyramid, and retirement rate. What makes the 60+ cut unique is the runway it gives you. The average U.S. retirement age is 62.3. Full Social Security benefits kick in between 66 and 67. Setting the threshold at 60 gives HR two to seven years of planning time before the average employee in that cohort walks out the door. Setting it at 55 is too early to be actionable. Setting it at 65 is often too late.
The metric has become more important in the last decade for three reasons. First, the share of U.S. workers aged 60 or older roughly doubled between 2000 and 2020, from under 7% to over 14%. Second, 10,000 Baby Boomers turn 65 every single day through 2030. Third, the median tenure for workers aged 55 to 64 is 9.6 years, more than triple the 2.7-year median for workers aged 25 to 34. That depth of institutional knowledge is exactly what disappears when a 60+ cohort retires without a plan.
The Aged 60+ Formula
Aged 60+ (%) = (COUNT of Active Employees Age ≥ 60 ÷ COUNT of All Active Employees) × 100
Step 1: Count every active employee on your payroll as of the reporting date. "Active" means currently employed. Exclude terminated employees, employees on unpaid leave beyond your standard policy, and contingent workers.
Step 2: From that same list, count every employee whose age is 60 or greater on the reporting date.
Step 3: Divide the aged 60+ count by the total active count.
Step 4: Multiply by 100 to convert to a percentage.
Most HR analytics platforms calculate this on a snapshot basis at the end of each month or quarter. A few use a trailing 12-month average to smooth out seasonal hiring and terminations. Both are valid. The snapshot method is simpler and easier to communicate to executives. The trailing average is more accurate for organizations with heavy seasonal staffing.
Some teams use age 55 or age 65 instead of 60. The 55+ variation aligns with SHRM and CIPD older-worker guidance, but it pulls in employees who are often a full decade away from retirement. The 65+ variation matches BLS labor force reporting, but by then retirement is already in progress. Age 60 sits in the analytical sweet spot for workforce planning.
Worked Example
Meridian Precision, a PE-backed industrial manufacturer with 1,400 employees across four U.S. plants, runs its quarterly workforce review. The HR team pulls the age data from Workday:
- Total active employees: 1,400
- Employees aged 60 or older: 182
Aged 60+ = (182 ÷ 1,400) × 100 = 13.0%
On its own, 13% is not an alarming number. It sits just above the national median. But the CHRO segments the result by plant, role, and department before presenting to the PE sponsor. The segmentation tells a very different story.
The legacy Pennsylvania plant, which the company has owned for 25 years, has 18% of its workforce aged 60 or older. The two recently acquired plants in Texas and Georgia sit at 8% and 9%. The skilled trades population, which the company relies on for CNC machining and tool and die work, is 29% aged 60+. The engineering group is 21%. Frontline production workers are 9%.
Now the number is a warning. Inside two years, roughly 30% of Meridian's most specialized, hardest-to-replace workers will reach the average U.S. retirement age. The replacement pipeline for CNC machinists takes 18 to 24 months of on-the-job training. The sponsor's value creation plan assumes flat labor costs and stable production capacity. Neither assumption survives contact with this data.
The CHRO uses the segmented view to build three responses: a phased retirement program for the Pennsylvania plant, an apprenticeship pipeline with two local technical colleges, and a knowledge-capture initiative for the top 15 skilled trades roles. None of those actions would have happened if the team had only reported the headline 13% figure.
HRBench Benchmark Data
Here is the national benchmark distribution for Aged 60+ across all HRBench customers. Use it as a directional reference for whether your workforce skews older, younger, or at the median.
A company at the 25th percentile has 7.6% of its workforce aged 60 or older. The median is 10.7%. The 75th percentile is 15.3%. If you are above the 75th percentile, the question is not whether you have retirement risk, it is whether you have time to build a response.
What Data Do You Need to Calculate Aged 60+?
The calculation requires only two inputs, but the quality of those inputs matters more than most teams realize.
Employee date of birth. This should live in your HRIS as a required field on every active employee record. Audit the field for completeness before running the metric. A 5% missing-birth-date rate can swing your Aged 60+ percentage by two or three points.
Active employment status. Your HRIS should distinguish active employees from terminated employees, employees on long leave, and contingent workers. Be explicit about which statuses count. Most organizations include employees on short-term leave and exclude employees on long-term disability.
Edge cases to decide in advance:
- Rehires. Count them as active as of their rehire date, not their original hire date.
- Acquired entities. If you just closed an acquisition, decide whether the new headcount gets blended into the enterprise metric or reported separately until integration is complete. Blending too early can hide a retirement cliff inside one business unit.
- Part-time employees. Include them if they are on direct payroll. Part-time status does not change the retirement risk they represent.
- Contractors and 1099 workers. Exclude them from both the numerator and denominator. If you rely heavily on contract labor, track a separate extended-workforce version of this metric.
Why HR Leaders Need to Track Aged 60+
Retirement Risk and Succession Planning
The metric is the leading indicator behind your retirement rate. A high Aged 60+ percentage today becomes a high retirement rate tomorrow. The gap between the two is the window HR has to build successors, document processes, and transfer knowledge. Organizations that wait for retirements to show up in the exit report are already two years late.
Knowledge Transfer and Institutional Memory
Workers aged 55 to 64 have a median tenure of 9.6 years. That tenure is where your undocumented processes, customer relationships, and tribal knowledge live. APQC research found that 41% of organizations "rarely or never" attempt to collect knowledge from retiring employees. A high Aged 60+ figure should automatically trigger a knowledge-capture program, not just a hiring plan.
Workforce Planning and Labor Cost Modeling
Most workforce plans assume stable headcount or linear growth. A concentrated Aged 60+ population invalidates that assumption. If 20% of your finance team retires over three years, the real question is not "can we hire replacements?" but "will our replacements be productive before the next budget cycle?" Answering that question changes hiring velocity, training investment, and contract labor forecasts.
PE Value Creation Plans and M&A Diligence
In a PE-backed company, workforce demographics are a balance sheet item hiding on the org chart. A target with 22% of its skilled workforce aged 60+ carries a transition cost that usually does not appear in the CIM. Sponsors increasingly request this metric in diligence because it forecasts labor availability and training costs in the first two years post-close.
Executive and Board Reporting
The Aged 60+ metric is one of the few workforce measures that translates directly to a board-level concern. Boards understand headcount and EBITDA. They do not always understand retention or eNPS. But they understand "30% of our skilled trades workforce will hit retirement age before the end of the hold period." That sentence drives budget.
Compliance and Risk Monitoring
The Age Discrimination in Employment Act protects workers 40 and older. Tracking Aged 60+ is not only legal, it is strongly recommended as a compliance signal. When viewed alongside promotion rates, training access, and involuntary separation rates for the same cohort, the metric surfaces potential adverse impact patterns early. Flat or declining 60+ representation when the broader labor market is aging can itself be a warning.
Benchmarks and Interpretation
External benchmarks provide helpful context, but internal trend is a more useful signal than any single outside number. That said, a few reference points are worth knowing.
By industry. Healthcare essential workers run around 15% aged 60+ according to AARP data. Manufacturing trends in the 10-12% range but carries heavy concentration in skilled trades. Utilities is the most dramatically aging sector, with 80% of utilities firms reporting that 25% or more of their workforce is aged 55+. Hospitality, food service, and retail sit at the low end.
By geography. Rural counties and northern U.S. states skew older. Maine, Vermont, and New Hampshire have the highest share of aged workers. Utah and Texas skew youngest.
By company size and stage. Smaller and older organizations tend to have higher Aged 60+ percentages because their workforce has been stable longer. Fast-growing companies tend to be younger because they hire aggressively at junior levels.
What "good" looks like. There is no universally good Aged 60+ number. A stable professional services firm at 18% is in a different position than a fast-scaling SaaS business at 5%. The stronger signal is whether the metric is trending up, flat, or down, and whether your succession coverage is keeping pace with your retirement risk.
Common Mistakes
Reporting the enterprise number without segmentation. A company-wide Aged 60+ of 10% can mask a 30% concentration in a single department. Always segment by function, location, and job family before drawing conclusions.
Treating the metric as an HR statistic instead of a planning input. Aged 60+ only matters if it triggers action. If the number shows up in a dashboard and nobody builds a succession plan, you are measuring retirement risk without managing it.
Confusing average age with Aged 60+. A 42-year-old average age can hide a bimodal workforce where half the employees are 30 and half are 58. Average age smooths out the clustering that actually drives retirement risk.
Ignoring rate of change. A company at 8% aged 60+ that has been growing 2 points per year is in more danger than a stable company at 15%. The trajectory tells you whether you have time to respond.
Failing to exclude part-time and contractor noise inconsistently. If you include contractors one quarter and exclude them the next, your trend line is meaningless. Pick a definition and hold it.
Letting the metric trigger discriminatory action. Using Aged 60+ to inform succession planning and knowledge transfer is lawful and smart. Using it to inform reductions in force, promotion decisions, or training denial is an ADEA violation. The line is clear: plan for transitions, never engineer them.
Reporting without tying the number to retirement rate and succession coverage. Aged 60+ in isolation is noise. Paired with retirement rate and succession coverage, it becomes a complete picture of demographic risk.
Related Metrics
- Average Age of Workforce: The mean age of your active employees. Useful as a directional indicator but hides age clustering.
- Retirement Rate: The percentage of employees who retired in a given period. The lagging outcome of high Aged 60+ percentages.
- Succession Coverage: The percentage of critical roles with at least one named, ready successor. The best response metric for a rising Aged 60+ trend.
- Rookie Ratio: The percentage of employees with less than one year of tenure. A high rookie ratio paired with a high Aged 60+ means you are losing depth on both ends.
- Employee Turnover: Overall separation rate. Retirement is a subset of turnover but behaves differently and requires different interventions.
- Headcount Growth: Net change in workforce size. Growth can mask retirement risk if new hires are concentrated in functions that already have young workforces.
- Employee Tenure: Average and median years of service. Long tenure plus high Aged 60+ equals high knowledge-loss risk.
