OCity planning estimates. National occupation references are inputs; displayed city values are modeled rather than direct local BLS occupation rows.

O'Fallon salary model: formulas, sources and limitations

Stored occupation model comparison

modeled estimate ÷ stored national reference = row comparison

On this owner, estimate-to-reference ratios are 0.314×–1.483× across occupations. Ratios can vary by occupation, so this is not described as one citywide multiplier or a direct local OEWS download.

Purchasing-power equivalent

modeled estimate ÷ 96.3 × 100

This comparison does not estimate taxes or take-home pay and is not an official BLS adjustment.

Limitations. “Average” is unweighted across selected occupations. Growth fields are national occupation projections, not local forecasts. City and metro geographies can differ. Repeated stored employment counts are not presented as local jobs.
