ANALYSIS OF DISTRIBUTION AND CHANGES IN SEX-STRUCTURE OF RANCHI DISTRICT (JHARKHAND)

Author: Savita Kumari 

ABSTRACT

In population geography, Sex-Structrue is one of the most important factors of population composition and this is studied as Biological composition of any population. Sex is an easily identifiable characteristic. The numerical measurement of sex composition of a population is known as sex ratio. Sex ratio is considered as an important index of economy prevailing in an area and is useful tool for regional analysis. For the study of the Sex-Structure of any population the two important measures are generally adopted as the percentage of males in the population and second, the sex-ratio. The latter is more frequently used in the study of population. Fertility signifies the actual incidence of live births in a population. It is an important demoraphic determinant of Sex-Structure of a population. The age and sex specific incidence of death has a direct effect on the overall sex structure of a population. Migration is the third important process which may change the sex composition of a population. The meaning of sex-composition or Sex-Structure is to know about the ratio of males and females in any population. It is very necessary for population geographers to know about the sex ratio of any population because balance of any society may be depends upon it’s balanced sex ratio. But, there are different reason which are responsible for unbalanced sex ratio such as nature of males and females. Because this nature of males and females are acts sometimes as complementary with each other and sometimes acts opposite against each other. Economy of any region can be understand through the sex ratio of that region. Sex-ratio is one of the most important tool for analysis of regional differences. The sex ratio of the total population at a point of time is known as “The overall sex ratio.” The sex-ratio is also shown the socio-economic conditions of any region. It also affects the demographic structure of any region. Sex-ratio is calculated differently in different countries. In India, the sexratio is calculated in terms of number of Females per thousand males. Sex-ratio can be measured from the time of conception to the time of death. This study gives us description and analysis about Sex-Structure and it’s distribution and changes in Ranchi district. The distribution and changes of Sex-Structure of Ranchi district affects total population of the district particularly in Rural and Urban areas. The Sex-Structure also influenced the Socio-Economic conditions of the Ranchi district gradually. The purpose of this study is to analyze the distribution and changes in Sex-Structure. The present study is an empirical research conducted in Ranchi district (Jharkhand) which is based on secondary data. In this paper an attempt has been made to throw light on the very important issues of analysing distribution and changes in Sex-Structure.

Keywords: – Sex composition, Sex-ratio, Fertility, Birth Rate, Mortality, and Migration.
