Ⅰ. The density of population was very great disparity. The distribution of population was disequilbrium.
Ⅱ. The general trend of the populous distribution was that is decreasing progressively around the centre of the New City Square.

According to the Colin Clark's formula.
d=de0-βx
Through the statistical analysed the census datas of third times of 1990, 1982 and 1964's. We can got the following formula.
dx=50892.457e-0.32924x
dx=51974.922e-0.38286x
dx=55072.095e-0.46979x
To compare with them, can discover:
A). In the centre of Xian, it's population density value (d0) had reduced from 55072 per square kilo to 51974 per square kilo. Up to 1990, it had reduced to 50892 per square kilo. The reduction was notable.
B). The gradient of population density (b)is becomming alleviation while the time's going on and the dimesion's exploitating of the city.
