Income Distribution and Inequality in Three Key Cities in Mindanao


The study tried to describe and compare the income distribution and inequality in three key cities in Mindanao namely: Cagayan de Oro City, Davao City and General Santos City. It made use of the data from the 2002 Family Income and expenditures survey conducted by the National Statistics Office.
Population shares and income shares of families in different income levels were determined. Income inequality was measured using the Gini coefficient. The Lorenz curves were also constructed for the three cities to have a clearer picture of the inequality.
Whi le Davao City has the highest number of families included in the survey consisting of 227,960 families, it has also the lowest average family income. Thus is Php155,937. For Cagayan de Oro City and General Santos City, there were 98,937 and 82,907 famili es, respectively that were included in the survey. And their corresponding average incomes are Php176,937 and Php164,900, respectively. Moreover, the lowest income level of Cagayan de Oro City is Php20,000 – 29,999, while that Davao City and General Santos City are both at Php10,000 – 19,999.
The Gini coefficient obtained for Cagayan de Oro City, Davao City and General Santos City are 0.395, 0.384 and 0.555, respectively. With Davao City getting the lowest coefficient, indicates that it has lowest inequal ity. Hence, the gap between the rich and the poor is smallest in Davao City than in the other two cities. The value of the coefficient is highest in general Santos City. This indicates biggest inequality among the three cities.
