Data Definition and Provenance: A Dashboard on My Number Card Dissemination and Utilization

General

Daily Values

The average number of registrations per day is calculated as a reference value for the dissemination of each policy.
This is the sum over a period of time, divided by the number of days in that period.
For example, for My Number Card as the Health Insurance Certificate usage subscriptions, the dashboard calculates "average subscriptions per day (average of the latest month shown)".
This is calculated by dividing the total number of usage registrations in the latest month by the number of days in that month (e.g. 31 days in January).

Aggregation period (monthly)

Monthly totals, such as the number of applications, increase in holdings, and number of issues, are calculated as a reference for policy progress within a given period.
Monthly figures are totaled starting at the beginning of each month and ending at the end of each month.
