The Active Family Filter narrows your query to Families who have Family Start Dates within the range you run your report.

Adding this filter to a query will allow you to see families who were active based on their family composition start and end dates.

This filter, unlike the program active filter, does not rely on program enrollment, only on family composition dates.

If the family was built on 1/1/2019 and you run a report from 12/1/2018 - 12/31/2018, your new family will not be in the query results.
