Headcount Growth Rate

Headcount Growth Rate: Percentage change in headcount over a period.

Formula

Growth Rate = (Headcount end - Headcount start) / Headcount start × 100

Computable definition

The canonical formula in the GASP formula grammar. The MCP server compiles it to SQL over the datasets listed below.

(metric.total_headcount at period_end - metric.total_headcount at period_start) / metric.total_headcount at period_start

Unit: percent (the formula yields an unscaled ratio)

Data requirements

Grain: End-of-month snapshot · Frequency: Monthly · Aggregation: snapshot (month) · Staged: no · Main source: HRIS.

Field Dataset Type
employee_id employee string
employee_status employee string
snapshot_date employee date
Example SQL (Postgres)
SELECT (CAST((((SELECT COUNT(DISTINCT employee_id) FROM employee WHERE snapshot_date = :period_end AND employee_status = 'active')) - ((SELECT COUNT(DISTINCT employee_id) FROM employee WHERE snapshot_date = :period_start AND employee_status = 'active'))) AS DOUBLE PRECISION) / NULLIF(((SELECT COUNT(DISTINCT employee_id) FROM employee WHERE snapshot_date = :period_start AND employee_status = 'active')), 0)) AS headcount_growth_rate

From an agent: with the GASP MCP server, call lookup_metric({ "name": "Headcount Growth Rate" }) or generate_query({ "metric": "Headcount Growth Rate", "adapter": "<your adapter JSON>" }).
