This study explored factors determining income security of older Malaysians aged between 55 to 75 years,using a nationwide database on the economic and financial aspects of ageing. The sample comprised 1,841older respondents in Peninsular Malaysia. Logistic regression analysis was performed (Nagelkerke R Sq.= 0.48) to test the likelihood of selected socio-demographic and economic factors contributing to incomesecurity. The results indicated that 53% of the elderly were in the income secure category, earning per capitaincome above the poverty level. The three strongest predictors were current work, being male and of Malayorigin. The findings suggest that income security of older Malaysians can be strengthened by providing workopportunities with decent pay and self-employment opportunities to the elderly in informal urban and ruralsectors. Such strategies are of paramount importance to help reduce poverty and vulnerability, increase incomesecurity and ultimately the quality of life of the elderly.
