Concerns Regarding Data Quality

Ambiguity of labels.

Labels like “lost child/property” and “found child/property” were difficult to categorize, as the service offered to recover property should be very different from the service offered to return children safely home.

Mid-year start and end.

Because the data provided for 2019-2020 were for July - July we were not able to include these data in our final analysis, as these data duplicated a portion of 2019.
