The rates of private construction are also substantially different in desert localities from their non-desert controls (Fig. 5). The following general trends can be observed: • The overall rate of private construction is considerably lower in peripheral desert towns than in settlements located in central areas of the country, for all periods,.

Annual rates of private construction in the urban localities included in the sample (1965·1994) TIlls phenomenon, which is apparently due to the dispersion of population from major wban centers of the country, was somewhat less evident in peripheral desert areas. The disparities in growth rates between desert localities of different population size (Set I and Set 2) are indeed less substantial (Fig. 3). These data thus support the hypothesis that the effect of general wbanization and subwbanization trends appears to be delayed and attenuated in peripheral desert areas, compared with the country's central districts.

The natural growth rate is essential for the proper understanding of the processes of urban growth in particular geographic areas since this indicator reflects both socio-
