This study deals with the analysis of the spatial distribution of the population in total of 26 districts in Hail city.

The reasons for choosing this study subject are due to two main reasons: The detailed population data of 26 districts available during 2004 and 2010.

The second reason is the possibility of the data analysis with testing statistical significance available in the SPSS analysis tools and the graphical representation in Excel to deriving population and density distribution maps.

To achieve the objectives of the research, this study relied on the inductive approach in analyzing the spatial variance of the distribution of the total population and their density in the districts of Hail city.

The study methodology relied on the integrated employment of: 1- The statistical methods available in the Analyze tools of the SPSS23 software by applying the Shapiro-Wilk test in order to determine the statistical significance of Normality tests.

2- The application of four quantitative criteria to analyze the spatial distributions of the total population and the densities variations, namely: A - Population density.

B - The Lorenz curve and Gini's coefficient.

C- Z Standard-score.

D - The Index of Dissimilarity.

The data for this study is A- The cartographic data derived from the topographical map Sheet 4127-13 of (Hail North, with scale 1: 50000), used to describe the Hail city location and maps of the Districts map obtained from the High Commission for the Development in Hail region.

B- Population distribution data during 2004 and 2010 in a total of 26 districts in Hail city, and their areas data obtained from the High Commission for the Development in Hail region.

The Shapiro-Wilk test results indicated the Abnormal distributions of the districts areas, total population, density and Z Standard-score.

While the distribution of the Index of Dissimilarity is normal.

Also, The Gini's coefficient obtained by the Lorenz curve values of the population and districts distributions is ranged between 0.74 in 2004 and 0.80 during 2010.

It indicates the difference between the population spatial distribution of the districts areas.

The ID and Z values are similar with these results, and showed the variation in the spatial distribution patterns of the population (dispersed, random, clustered) during 2004-2010.

The statistical tests revealed the insignificance of the variation of the population data at different degrees of freedom.

Conclusion: This study concluded with some results obtained from the various methodological steps applied in Normality tests of the population and districts areas distributions, as well as the relationship between them during the years 2004 and 2010 in the studied districts of Hail city.

The statistical significance Index of Dissimilarity and standard Z values revealed that the spatial distribution pattern varied with some relative changes occurred between 2004 and 2010 (within 6 years).
