This one is not exactly what you want, but maybe helpful for your interests.
I made it by using reliable data dump by theymos, but it is not exactly monthly statistics.
Please use it with potential biases.

As I promised yesterday, I made some quick descriptive analysis today.

Time-series plot
Basic statistics:
- Mean +/- standard deviation: 21916 +/- 34795
- Median (interquartile range): 10145 (2311 - 25509)
- Min - max: 3 - 238433.

Interquartile range (from p25 to p75 in raw result table)
Data interpretation:
- 50% of observed total monthly registered accounts (just assumed the dataset is for exactly monthly data) ranges from 2311 to 25509 (the interquartile range);
- 50% of observed months have total registered accounts above 10145 (the median), whilst the rest 50% of months have figures below 10145.

Code:
. tabstat regacc, s(n mean sd p50 p25 p75 min max)

    variable |         N      mean        sd       p50       p25       p75       min       max

Data source was dumped by theymos there:
We're at a local minimum, but registrations jump around a lot:

In both medians and means, the year of 2018 has been the highest year with its median and mean of monthly registered accounts are 66895 and 64782, respectively.

- The median means that 50% of months in 2018 have total registered accounts above 66895 or below 66895.
- The interquartile range for 2018 is 36477 to 88373. It means 50% of months in 2018 have figures in range from 36477 to 88373.
I always use median and interquartile range for descriptive statistics because they automatically exclude effects of outliers data points.
