Abstract: The structure of the population in the Someşul Mic Valley according to gender, age groups and living environment between 1850-2002. The structure of the population in the Someşul Mic Valley according to gender, age groups and living environment has a number of peculiarities that show its relative individuality. The analysis by gender shows the fact that in this century and a half, there was a growth in the female population, from 50,60% in 1850 to 52,14% in 2002, while the masculine population decreased from 49,40% in 1850 to 47,86% in 2002. Therefore, the female population index (the number of women relative to a 100 men) grew from 102,4 in 1850 to 108,5 in 2002. Thus, between 1850-2002, the total growth of the women’s share was of 1,54%, with a clear dominance in the urban environment (from 51,54 % in 1850 to 52,34 % in 2002), while in the rural area the situation has reversed compared to 1850, when there was a male predominance (50,80%), so that in 2002 there is a women predominance (50,11%). The evolution of the Valley’s population by age groups shows a decrease of the young population (0-19 years of age) by 21,4%, from 43,6% in 1857 to 22,2%, an increase by 11% of the adult segment (20-59 years of age), from 51,3% in 1857 to 62,3% in 2002, as well as of the older one (over 60 years of age), which had the highest increase (10,5%) from 5,1% in 1857 to 15,6%. To sum up, this means a decrease to half of the young population and a three-folding of the old one, with the mention that in the rural area the growth of the older population is bigger (21,8%) than in the urban environment (40,2%). In what regards the situation of the Valley’s population according to the living environments we can see that this has a special status, as, even since 1850, the share of the urban population was higher (59,8%) than of the rural one (40,2%). After 152 years, in 2002, there is an exaggerate growth of the difference rural-urban, as the great majority of the population (90,9%) is now living in the urban area and only a small part (9,1%) in the rural one. Thus, out of ten inhabitants of the Valley, only one lives in the rural area, which shows an overcrowding of the urban environment, thus having negative consequences on the life’s quality.
Keywords: the structure of the population according to gender, age groups and environments; female population index, ageing index, age pyramid, population share.
