Tunceli Province is located in the Upper Euphrates Section of Eastern Anatolia Region. As you go from south to north, physical geographical features and human geographical features change depending on it. In this study, the distribution of populations and settlements according to topographic factors (elevation, slope and aspect) in Tunceli Province is discussed. The aim of the study is to determine the effect of topographic factors on the distribution of population and settlements. In this direction, the population data of Tunceli Province was downloaded from the Turkish Statistical Institute (TUIK) database in the Microsoft Excel environment and processed into the database of digitized settlements via topography maps. Then, the correlation of population and settlement data with topographic factors was evaluated in GIS. As the topographical factors in the research area change very short distances, the distribution of population and settlements also show differences. Since elevations between 798-1500 m have favorable physical geographical conditions, this elevations values is the most crowded of population (69,4%) and settlements (34%). Steep slopes (10-40%) have the widest spread in the slope groups and this slope group (74,9%) where the settlements are the most intense. The fact that the dominant aspect (42,4%) is southern and 46,4% of the settlements are collected in this direction has been the main reason for benefiting from the sun and protecting from negative weather conditions for population and settlements.
