stationariness

State of unmoving

Stationariness is the quality of being stationary—not moving or not changing.

The term appears most often in technical contexts: economists test time-series data for stationariness, and physicists discuss the stationariness of a system.

In ordinary speech, stillness or immobility usually suffices.
