Abstract (EN):
The rank-size model - which states that the size distribution of cities in a
country follows a Pareto distribution - has been recognized as one of those
stylised facts or amazing empirical regularities, in spatial economics.
A common problem in city size distribution studies concerns the definition
of ¿cities¿, namely the consistency of those definitions over time. In this
paper we use a city-proper data base which uses a consistent definition of
cities from 1864 to 1991. Portugal is a country with long established
national borders and whose mainland urban system shows a constant
number of cities over that period.
In Portugal, empirical evidence on city size distribution based on census
data shows that two large cities dominate the urban system, associated with
a large number of very small cities and a clear deficit of medium-size cities.
In this paper we analyse the evolution of the rank size exponent and
examine the effect of varying city size cut-offs on the estimated value of
that exponent. Then, we study the deviations of the rank-size distribution
from linearity. Finally, we explore the dynamics underlying the evolution of
the urban system by examining the relationship between city growth rates
and city size
