I added functionality to tilelog to generate per-country usage information for the OSMF Standard Map Layer. The output of this is a CSV file, generated every day, which contains country code, number of unique IPs that day, tiles per second, and tiles per second that were a cache miss, all for each country code.
With a bit of work, I manipulated the files to give me the usage from the 10 countries with the most usage, for the first four months of 2023.
Perhaps more interesting is looking at the usage for each country by the day of week.
