The major objective of this research study is to analyze the nature and impact of customer demographics (gender, occupation and tenure of banking) on the CRM awareness and efficiency from five select public sector commercial banks that are located in Hyderabad and Secunderabad cities of Andhra Pradesh state. A sample size of 2502 respondents was chosen and a survey instrument was designed to measure the relationship between the demographics and CRM awareness and efficiency. CRM efficiency was measured on a Likert scale of 1 to 5, where 1=Very Low, 2=Low, 3=Moderate, 4= High and 5= Very High. Chi-Square test was performed to asses the relationship between the respondents’ occupation and their perception of CRM awareness. This test was also used for testing the association between the tenure of banking and CRM effectiveness. The relationship between the gender type and customers’ bank preference was also tested by using Chi-Square test. In line with the research findings suggestions were offered to strengthen the service delivery in the Indian banks.
