Service Quality and Customer Satisfaction of Private Sector Banks: A Demographic Perspective from Madurai District

Abstract

The rapid expansion of private sector banks since the liberalisation of the Indian economy has intensified competition on the single dimension that cannot readily be imitated: the quality of customer service. This paper examines the demographic profile, service quality perceptions, and satisfaction levels of 480 customers of private sector banks in Madurai District, Tamil Nadu, drawn through a stratified random sample across urban, semi-urban, and rural centres. Customer perception was measured across eight service quality dimensions – core banking, physical infrastructure, digital banking, loan and credit services, staff behaviour, grievance redressal, ancillary services, and overall satisfaction – using a validated, pre-tested interview schedule (Cronbach's Alpha = 0.876 at the pilot stage; 0.935 to 0.992 on the full sample). Descriptive analysis showed uniformly favourable mean scores (3.96 to 3.99 on a five-point scale) across all eight dimensions. Independent samples t-test and one-way ANOVA were employed to test whether satisfaction varies across gender, age, education, occupation, income, area of residence, frequency of visits, and bank dealt with. Seven of the eight demographic hypotheses were accepted, indicating that satisfaction is broadly invariant across customer segments; only educational qualification showed a borderline significant association (p = 0.0499). The findings suggest that private sector banks in Madurai District deliver a consistently favourable, demographically inclusive service experience, and the paper offers specific, evidence-based suggestions for sustaining this consistency.
