This study examined factors associated with the ownership of stock investments and the amount of stock investments of households using the 2001 National Survey of Family Income and Expenditure by National Statistical Office. Households with large amounts of income, savings, and liabilities were more likely to invest in stocks and have large amounts of stock investments. Also, households with young and male householders, highly educated householders, a number of children in school, and housing ownership were more likely to invest in stocks and have large amounts of stock investments. On the other hand, self employed households and dual income households were less likely to invest in stocks and have small amounts of stock investments.
