摘要：AbstractKarabük city has been a street with a population of 13 houses in 1937 as a village affiliated to Safranbolu. It has grown rapidly after the establishment of Kar-demir and population reached over 100 000 theirby changing into a modern city of middle scale. The population increase is directly related to the employment capacities at Kar-demir, because iron and steel industry form the economical base with no comparison to other sectors. The purpose of this study was to put forward the effects of Kar-demir over the demographic developments of Karabük City.The data was collected from TÜ_K and several other institutions and evaluated through descriptive research method. The results showed that this city has always taken immigrants since 1937 when Kar-demir was established followed by big developments. Karabük was declared as a county in 1953 and as a province in 1995. An examination of the population change in the city center reveals that in 1940 it was 6825, went up to 84137 in 1980 and 105159 in 2007. Demographic developments show a stabilisation in the population because of the same levels in 1990 and 2007. The reason behind this seems to be the crisis which took place in mid 1990s and the decisions about first closing up and then privatization of Kar-demir.
