The Diocese of Nikopol in northern Bulgaria has only some 30,000 Catholics out of a population of almost 3 million. While there are 20 parishes in the diocese, not every parish has its own priest due to a general shortage of priests.
In all this unimaginably vast territory there are just 50 priests or so ministering to a widely scattered population of 50,000 or so Catholic faithful. Often these are no more than tiny communities, in some cases just a single Catholic family, with the next nearest Catholic community hundreds if not thousands of miles away.
The Diocese of Miao lies in one of the most remote and inaccessible regions of India, in the state of Arunachal Pradesh in the far Northeast, a region bordering on China, Tibet and Burma (Myanmar). In fact, because it is so close to the Chinese frontier, outsiders need a special official permit to stay in the region.
