Demography is the scientific study of characteristics and dynamics pertaining to the human population, including things like size, growth rate, density and distribution of a specified group. The primary reason people use demography is to create statistics-in fact, the term roughly translates to "people measurement." These allow a person to get a picture of how common specific traits within a group are. Comparing statistics over time also allows researchers to show changes that are happening in the target group. A research survey was undertaken to ascertain the 'Association of Demographic Variables versus the Frequency of Usage of Core Aerospace Engineering e-Databases' amongst the aerospace scientists and engineers of selected 16 aerospace organizations of Bangalore. The major findings of this study are: The χ2 test indicates that the demographic variable, viz., Category Wise Distribution of the Respondents, namely: Aerospace Scientist / Aerospace Engineer(χ2=20.832, P Value = 0.000), Occupation(χ2=65.978, P Value = 0.000), Qualification(χ2=28.207, P Value = 0.005), and Specialization(χ2=42.228, P Value = 0.003), by the 'Frequency of Use of Core Aerospace Engineering e-Databases' have significant association. This implies that the percentage of preference for the above mentioned demographic variables are not approximately the same [Not Uniformly distributed]. The χ2 tests for the remaining demographic variables, namely, Gender and Age-Group by the 'Frequency of Use of Core Aerospace Engineering e-Databases' have no significant association. This implies that percentages of preference for these demographic variables are approximately the same [Uniformly distributed].
