Corporate Social Responsibility (CSR) is relevant to mainstream thought on economic organisations and their places in society. The aim of this paper is to collect some of the most relevant research findings on CSR, introduce the informedness of Hungarian respondents on CSR in general, the main influencing factors of their purchasing decisions, and to find correlations between the received results and the demographic variables based on our primary research. Our results support the present practice in terms of the definition of CSR. Almost all the listed alternatives are strongly associated with CSR by the respondents. The highest average received for the “creating work places, employment” alternative indicates the importance of this activity. Regarding the different factors influencing purchasing decision, our results underline the importance of price and price value ratio.
