This article addresses age variability in some Azerbaijani cephalometric features, based on study of the population of two closely related and neighbouring villages (Lower and Upper Askipara). They represent the Azerbaijani enclave in the territory of Armenia. The majority of this population is native to the area. Research took place in 1985 and studied approximately 40 % of the adult population (equally men and women) using the parameters of programmes of ethnic anthropology. Attention was paid only to the measurement characteristics that are relevant in relation to their correlation with the age of the studied group (there were 11 correlations). Six of them characterize the skull, which is forming in ontogenesis by ossification of connective tissue the bubble (nota textus bulla). The other five characteristics are formed as a result of cartilaginous tissue substitution. The analysis of the studied group leads to the following conclusions. Age variability of some measured features of the head is detected. Age-related variability of the measured characteristics of the arched part of the skull usually showed a reliable negative correlation in their values with age. It means that the older generation had smaller values than the younger ones had. The values of the facial bone structure did not show such a clear correlation with age, except the zygomatic and mandibular diameters. They usually showed a small reliable positive correlation with age. So, these features had a larger value in older age than in younger. These results were observed in both men and women of both villages, but more clearly expressed in the population of Lower Askipara (this village is larger than Upper Askipara). Of all the studied signs the highest and most stable negative correlation with age showed the greatest head width, cephalic index, the degree of sphericity and the relative height of the cranial vault (pointer lipsiense). For a short time (about 50 years) variability of the metric parameters of the head were investigated in a small, isolated population of Azerbaijanis showing the same temporal vector, which is characteristic of evolutionary changes (secular trend) in a significant part of the population of Eurasia: brachycephalidae, spherisation of the cranium and the increase of the cranial vault. To determine at what age there was the greatest variability of va-lues, the study divided the population of both villages (separately by sex) into three age groups: younger age from 19 to 39 years (born after 1945), average age from 40 to 54 years (born between 1930 and 1945), older age 55 years or more (born before 1930). In both men and women, the selected age groups were close in number. When the studied sample was divided into three age groups, it was found that the greatest variability of values and their correlation with age were recorded in both men and women in the younger aged group: 19
39 years (born after 1945).

Key words: Azerbaijani population, brachycephalidae, spherization, Lower and Upper Askipara.
