A few weeks ago, I wrote a blog post about the inequities between countries regarding the minimum size of OSM maps that can be downloaded. From my experience as a traveler, I had figured out that for some countries, only a large scale was available, and downloading was difficult when the internet connection was unreliable.
I used a script to rank the country information from https://download.osmand.net/list.php by file size within each subcontinent. For example, Nigeria, the most populous country in Africa, only has one map at a scale larger than 600 MB.
There is little explanation for this situation except for a comment suggesting that a request for smaller map files was never made for these countries. In any case, I think it can easily be fixed.
PS: Is there any data available on how many times each map file has been downloaded?
