Stats: Efficiency Factor

Postcrossing General Topics

Using PC statistics you can determine the ratio of the number of received postcards to the number of lost postcards.
This can be calculated by the ratio of the number of elongated numbers and the number of registered postcards.
For example, for Russia, only 7 out of 8 cards are registered :slightly_smiling_face:

Thanks for the comment.
This table only reflects the general trend by country.
A lot of things here are based on the forecast.
As of January 09, 2022, Finland has sent approximately 3864100 postcards.
Usually in 2 months the postcard either reaches the goal or is lost.
On November 09, 2021, circa FI-4057500 was issued, on December 09, 2021, circa FI-4078200 was issued.
The success rate is 95.2% and 94.8%, respectively.
On the other flank is China. Here the percentage is 83.7 and 83.2 respectively

For Canada, 12 out of 13 postcards found a new owner, and 1 postcard was either lost or forgotten to be sent :grinning:
