My occupation is a statistician. I tell people it is like "CSI without dead bodies" because analyzing a set of data that has been collected is like doing an autopsy on a deceased person in the sense that I'm trying to learn what I can from what statistics and information are available. Except in this case the information does not involve gross things. For me the research process can be humorous, scary, but always captivating.

Corona Numbers from the WHO and JHU
At the left is the WHO's world wide cumulative frequency chart from today. The number of cases increased by 123,535 or 87%. The number of deaths increased by 5,793 or 107%.
The two curves show that after the curve was starting to flatten out (mostly in China), it began to increase exponentially in early March everywhere but China. The mortality rate for the total number of cases a week ago was 3.8%. Currently the rate is 4.2% with it being the highest in Italy where it is 8.6%.
Johns-Hopkins University (JHU) also has a dashboard that is frequently cited in the news media. Their reported numbers are higher than the WHO's. They report 287,238 cases worldwide with 11,942 deaths. The mortality rate according to their numbers is also 4.2%.
The JHU dashboard also provides the numbers of people who have recovered from the virus. According to them, 89,899 have recovered worldwide from the virus or 31% of the total cases. The graph above shows the cumulative number of cases in mainland China (orange line) and the cumulative number of cases everywhere else (yellow line). We can see that the yellow line is still growing while china's line has flattened. The number of recovered cases has been growing steadily.

The numbers for each country differ between the two dashboards. The top 10 countries with cases are presented above with the number of cases reported. The two dashboards agree on the countries in the top 10. The order that the countries are ranked agree except for Iran and Germany which are flipped for fourth and fifth. The two dashboards agree on the number of cases only for Italy and South Korea. The greatest discrepancies for the two dashboards are for Spain (-5,394), the US (-4,712), and Germany (-3,329) with JHU having more cases.
Certainly there is confusion keeping track of all the cases in a world with more than 7 billion inhabitants. The countries most affected are some of the richest and most powerful in Asia, Europe, and North America with the exception of Iran. Until the curve of new cases flattens out the state of emergency is likely to continue. The video below gives a good summary of how epidemics and pandemics progress.

9th Anniversary Post: Evaluating the Domain Name
Overall there was a 128.8% increase in the number of users in the past year (mostly in the first three months of last year). Likewise there was a 130.21% and a 129.06% increase in the number of new users and sessions respectively. There was a slight increase in the number of sessions per user (0.11%). However there was only a 20.65% increase in the number of pageviews and a 47.33% decrease in the number of pages per session. There was a smaller decrease in the average session duration but a larger increase in the bounce rate. This suggests that while the number of users has increased, the level of engagement hasn't.
Looking at the countries where the users came from, there was a 4,426.09% increase from India, a 2,400% increase from Nigeria, a 2,000% increase from Bangladesh but an 85.13% increase from the United States. Looking at the United States, there was a one second increase in the average session duration. There was a decrease in the pages per session in the US but It was higher there (1.85 pages per session) than it was in the page overall (1.71 pages per session). This suggests that the low engagement comes from outside the US which makes sense as most of my posts are about the US.
I counted 50 posts to the blog in the last year. With 415 total posts on the blog over the last nine years, that averages out to 46.1 posts per year so it has been a productive year. I will continue the domain name from google to promote my blog. On to the tenth year.
