# Workforce Composition Metrics

# Workforce Composition Metrics

## Headcount

**Definition:** The number of individual employees in a unit/role combination at the end of the period.

**Type:** Integer count — one person = one headcount regardless of FTE status.

**Notes:**

* A 0.5 FTE part-time employee counts as 1 headcount
* Headcount counts people, FTE counts capacity
* Use headcount for understanding team size; use FTE for capacity planning

## Positions

**Definition:** The number of budgeted or authorized positions for a unit/role combination.

**Type:** Decimal — positions can be fractional (e.g. 2.5 positions = two full-time and one half-time).

**Notes:**

* Positions represent funded establishment, not necessarily current budget approval
* Some organizations track positions as headcount positions (integer) rather than FTE positions (decimal) — be consistent
* The gap between positions and filled FTE is the basis for vacancy calculations

## Filled FTE

**Definition:** The full-time equivalent of the current employed workforce.

**Formula:**

```
FTE = sum of (hours_per_week ÷ full_time_standard_hours) for each employee
```

In practice, FTE is typically provided directly from your HRIS or payroll system rather than calculated in Senzo.

**Notes:**

* Standard full-time hours vary by collective agreement — typically 37.5 or 40 hours/week
* A 0.8 FTE employee works 80% of full-time hours
* FTE is the most meaningful measure of workforce capacity

## Budgeted FTE

**Definition:** The FTE capacity that has been budgeted for the period, which may differ from authorized positions.

**Notes:**

* Budgeted FTE reflects financial planning; positions reflect operational establishment
* In many health systems these differ — funded positions may be held vacant for budget reasons
* Upload as `budgeted_fte` if your system tracks this separately

## FTE Vacancy Rate

See [Vacancy Metrics](/metrics-reference/vacancy-metrics) for full definition and formula.

## Notes on composition data quality

Common issues with composition data:

* **Headcount includes temporary or agency staff** — ideally exclude agency staff from headcount; track their hours separately in `agency_hours`
* **FTE not updated mid-period** — FTE should reflect the end-of-period state, not an average
* **Positions not maintained** — if your organization doesn't actively maintain a position register, vacancy metrics will be unreliable
