Attention to heritage area and old texture is very usual in Iran. Since last two decades, revitalization and
renovation of historic cores has begun partly in some of the traditional Iranian cities. Historic centre of
Isfahan is among the most important cases in central part of Iran. The aim of the conservation of
heritage areas in this city is to revive the past image, restoring the ancient parts which still survive, and
to adapt the traditional fabric to use in modern life. In this paper, we try to find the relationship between
population trends, employment structure, marital status and size of the housing units in the 1st and 3rd
municipality district in historic center of the Isfahan city. The result of this present study shows
principles which are considered uneven in distribution of population in heritage textures of Isfahan.
