Fields#
| field | type | required | note |
|---|---|---|---|
name | text | yes | |
unit_kind | Kind | yes | |
readers | {text:text} | yes | for each speed of the preview and for live evaluation |
state | Readiness | yes | a population with no reader is not ready |
sample_strata | [text] | no | the attribute paths whose values stratify a preview’s sample, so the sample is spread over them |
Routes that use it#
No route takes or returns Population directly. The record holds it, and the objects that point at it reach it.
