The study investigated the level of social media use and online purchase decisions among 330 senior citizens in Estancia, Iloilo, using a researcher-made questionnaire. Results showed that social media use among seniors was moderate overall, but varied by age, sex, and income, with those aged 60-70 and earning below 10K more likely to engage in online purchases compared to those over 70 with higher incomes. There was a significant relationship between the level of social media use and online purchase decisions, indicating that differing demographic factors influence these behaviors.
