# Query population logs

> Returns a LogQuery builder scoped to the whole organization or an explicit patient cohort.

```python theme={null}
olira.population_logs(patient_ids: list[str] | None = None) -> LogQueryResult
```

**Requires scope:** `sdk:state-read`

Omit patient\_ids (or pass None) for org-wide queries; pass a list to restrict to a cohort. All chainable builder methods are identical to logs — see that entry.

## Parameters

<ParamField body="patient_ids" type="list[str] | None" default="None">
  Cohort of patient ids. None = whole org. Omitting queries all patients org-wide — use filters and limits when running at scale.
</ParamField>

## Returns

`LogQueryResult` — Same shape as logs — call .execute() or another terminal to run.

<ResponseField name="count" type="int">
  Total rows matched.
</ResponseField>

<ResponseField name="rows" type="list[dict]">
  Log dicts or aggregated dicts.
</ResponseField>

<ResponseField name="organization_id" type="str | None">
  Echo of the org id.
</ResponseField>

<ResponseField name="patient_id" type="str | None">
  Null for population queries.
</ResponseField>

## Raises
