What's it like to live in the country with the fastest-shrinking population in the world? In the mountain village of Kalotinsi in western Bulgaria, there is no shop, no school, no bus service. Until a few decades ago, 600 people lived here but now most of the houses stand empty. Thirteen residents remain, struggling to make a life in a place most people have given up on. There are many other near-deserted villages like this in Bulgaria. With women having few children, and many choosing to work abroad, Bulgaria is facing a population crisis. Ruth Alexander travels to the country to find out what life is like for those left behind, and to ask what is being done to reverse the population decline.
