How long of a timespan would this map cover? Does this only work for the late 19th century, or do most of these populations and percentages tend to stay the same throughout the 19th- maybe even the 18th!- century?
Nobody has any idea what the populations were before 1840, and even then info was very spotty. This is a snapshot at about 1874-75. It's likely they were not too much different throughout the 19th c, but there were a lot of wars prior to that where populations may have changed - for example I've read that the Nish area at one time had a Muslim majority - I suppose that's possible if the region had been largely depopulated in wars...
In 1877-78 the balance changed a lot, with Bosnia losing a considerable number of Muslims and Bulgaria losing about 1.3M. That made the remaining parts of the empire in Europe even more heavily Muslim, as most of the refugees ended up in Thrace and Western Macedonia. By the 1880s, the remaining Ottoman Balkans were just over 50% Muslim.
