| # ICE facility, office and jurisdiction references — dictionary |
|
|
| All original source fields retain their source meanings. The table unit and time semantics below are required context; names alone do not define a universal measure. Exact NULL counts are distinct from empty strings, empty geometry and source-coded missingness. See README for known anomalies and the immutable source lock. |
