Abstract:
With the fast expansion of urban areas and employing densification policy in Iran, urban density analysis has found high attention in urban development debates. But urban population density has many dimensions and varies from one city to another. Thus, employing statistical methods that use existing data of public censuses are very useful for analysis of existing conditions, proposed condition and its classification.
In this paper, distribution of population density in the city of Tabriz in recent decades has been studied and analysed with the use of public census data and other official data. Some statistical methods such as linear and non-linear model, correlation coefficient and multi- correlation methods have been used for density analysis.
Some findings of this research are: achievement to a model for explain of relation between population growth and expansion of tabriz urban area; a model to explain quantitative distribution of population and to analyse factors that affect urban density.
The main goal of this research is to achieve some methods or techniques for surveying, classifying and forecasting urban density.
Keywords:population density, spatial distribution, density classification, density changes.
