Blog > Postcrossing in numbers: 2017 stats
On our open poll, many of you asked to see more statistics on the blog, so we thought we’d introduce a new series of posts all about Postcrossing and numbers. And what better way to start than by looking at some of the data from the year that just ended, right? Let’s do this!
5,425,005 postcards received
That’s right — almost 5.5 Million postcards were registered last year, which was pretty neat! We’ve just passed the 45 million milestone a few days ago, and are on track to celebrate the big 50 later this year. Woohoo!
25.7 days (average) and 17 days (median) travel time
Do you know the difference between an average (or mean) and a median? To calculate the average of a set of values, you sum all the values in your set and divide them by the total number of items in that set. This is great if your values are more or less well distributed, but outliers (both large and small) often distort the end result disproportionately.
Enter the median, which can be roughly described as the “middle” value of a data set. If you put all the travel times in a looong ordered line, 17 days would be the value in the centre of this distribution. This is a more reliable value to determine how many days most postcards travel before reaching their destination. Some will be quicker, some will be slower, but on the whole, postcards seem to travel somewhere around 17 days.
27,380,992,088 km (or or 17,013,759,698 miles) of total traveled distance
That’s… yeah. I don’t have words for it neither. We’re way beyond Pluto at this point!
19,985 km (or 12,418 miles) was the longest distance traveled by a postcard
Below is the postcard that traveled the longest distance last year. Can you guess between which countries it was exchanged?
It’s a trick question because of the content… but if you guessed New Zealand and Spain, you’d be right! Postcard NZ-155857 traveled between a pair of antipodal points: from the north tip of New Zealand to the south part of Spain.
916,800 postcards were sent from Germany 🇩🇪
Germany was the most active country last year, with almost a million postcards sent from there! Here are the other countries and territories in the top 20:
|13||🇬🇧 United Kingdom||102,245|
|16||🇭🇰 Hong Kong||70,432|

Dedication and a speedy postal service helped the Germans climb to the top of the charts, where they took most of the top spots! Here are our 20 most avid postcrossers:
