Constructing Self-Organizing Poverty Maps from FIES and APIS (2002)

 

Abstract

The study exhibited an alternative mapping system that visually displays the structures of welfare relations among comparable geographic areas at the sub-national level (such as regions and provinces) based on a poverty database sourced from the Family Income and Expenditure Survey (FIES) and the Annual Poverty Indicator Survey (APIS). This mapping system is based on the Self-Organizing Map (SOM), also called the Kohonen Map or the Self-Organizing Feature Map. The results suggest that poverty structures and welfare relations among the regions do not change considerable over a period of time of three years. Moreover, this study indicates that poverty in the Philippines is largely a rural phenomenon. It recommends that poverty reduction programs that aim to enhance the income-generating capabilities of the poor must be targeted toward the rural areas.
