Review findings

Educational calculation from user-entered figures only. The formulas are standard once labor force is explicitly derived as employed + unemployed and ratios are converted to percentages. The exact unresolved ambiguity is whether labor_force is derived from the listed employed and unemployed inputs or is intended to be separately supplied.

Formula and scope findings

• The standard formulas are correct, but labor_force appears in both formulas and is not listed as an input; the specification must explicitly define labor_force = employed + unemployed or add labor_force as an input.
• The formulas as written produce decimal ratios, while the stated outputs are percentages; the implementation must multiply each ratio by 100 and label the results as percent.

Unit assumptions

• employed, unemployed, labor_force, and working_age_population are nonnegative counts measured in the same population unit.
• Labor force is assumed to equal employed + unemployed, with employed and unemployed mutually exclusive.
• working_age_population is the denominator population defined by the applicable statistical convention and includes the labor force.
• Percentage outputs are calculated as ratios multiplied by 100.

Boundary hardening

BREAK_CLAIMED · SELF_FLAGGED

A zero labor force produces unemployment_rate = 0/0, which is undefined and must be rejected or handled as an error. Inputs with labor force greater than the working-age population also produce mathematically defined but economically invalid percentages unless validation rejects them.

Inspectable example

4 review vectors are recorded. One source-bound sample is shown below.

{
  "inputs": {
    "employed": 1500,
    "unemployed": 100,
    "working_age_population": 3000
  },
  "expected_outputs": {
    "unemployment_percent": 6.25,
    "participation_percent": 53.3333333333
  },
  "working": "labor_force = employed + unemployed = 1500 + 100 = 1600; unemployment rate = unemployed / labor_force = 100 / 1600 = 0.0625; unemployment percent = 0.0625 × 100 = 6.25%; participation rate = labor_force / working_age_population = 1600 / 3000 = 0.5333333333; participation percent = 0.5333333333 × 100 = 53.3333333333%."
