When and where is a city fractal?

We present here an analysis of the development of the Tel Aviv metropolis b y using the concept of fractals. The fractal dimension of the entire metrop olis, and of its parts, was estimated as a function of time, from 1935 onwa rds. The central part and the northern tier are fractal at all times. Their fractal dimension increased with time. However, the metropolis as a whole can be said to be fractal only after 1985. There is a general tendency towa rds fractality, in the sense that the fractal dimension of the different pa rts converge towards the same value.
