The first degcity index DC1(G) of a connected graph G is defined as the sum of the terms [ex+ey][dx+dy] over all the lines xy of G, where dx and ex represents the degree and eccentricity of a point x in G respectively. In this article, we have obtained some lower and upper bounds of first degcity index.
