This study was conducted in Delta State to examine the consumption and expenditure patterns of public servants in Delta State. One hundred and twenty (120) respondents were randomly selected from Delta State Polytechnic Ozoro, sixty (60) each for junior and senior staff respectively. Structured questionnaires were administered to a cross section of the respondents. The data obtained were analyzed using the ordinary least squares method of multiple regression analysis, T-test statistic, deriving marginal propensity to consumer coefficients from simple regression model. The study revealed that female, (55%) constitute the majority of the employees in the study area. Most of the workers are young and energetic and represented the active labour force. Majority (69.17%) of the workers are married which indicated that a substantial part of their income was devoted to family upkeep. The empirical results further showed that there was a significant relationship between food consumption and expenditure on savings, investment, education, transportation and house rent at (p<0.05). It was further observed that workers spend more money on food and other things as they receive their salary. However, the marginal propensity to consume (MPC) of low income workers was 0.786 while those of high income workers was 0.965 showing that both groups set aside a large proportion of their income on consumption. It can be concluded that most public servants in Delta State spend more of their income on food, transportation, rent, among others than saves invest. Recommendations are therefore made to encourage workers to save and invest through periodic wage reviews, staff motivation and education, checking the rate of inflation and provision of adequate food at affordable prices.
