Enum: Privacy Transformation (PrivacyTransformationEnum)
A privacy-protecting transformation applied to a linked location after the spatial join, which alters the recorded location of the exposure. A deterministic hex-reassignment jitter is the motivating case.

permissible_values:
none:
text: none
description: No privacy transformation applied; the linked location is the true
one.
deterministic_geographic_jitter:
text: deterministic_geographic_jitter
description: The location is deterministically reassigned to a nearby unit under
a reproducible rule (e.g. reassignment to the largest hex in the same ZIP3 below
a population threshold).
suppression:
text: suppression
description: The value or location is suppressed (dropped / withheld) when a disclosure
risk threshold is exceeded.
aggregation_to_coarser_unit:
text: aggregation_to_coarser_unit
description: The location is coarsened to a larger geographic unit (e.g. hex →
ZIP3 or county) to protect privacy.
stochastic_perturbation:
text: stochastic_perturbation
description: The location is perturbed by a random (non-deterministic) offset
— contrast the deterministic jitter above.
