HOW TO READ THE MAPS

The municipal indexes are plotted using GIS tools and technology. Maps are made for the individual indicators, the composite indexes and the over-all poverty index.

Five intervals are used in the maps. Two intervals with ranges 0-49 percent and 50-99 percent represent the performance of the municipalities whose achievements are better than either the provincial or the national values. The 100-149 percent range would include the municipalities with performance at least equal to but not more than one-and-a-half times the provincial/national value. Similarly, the 150-199 percent and 200 percent and over ranges would indicate the municipalities which are worse than the provincial situation.

The poverty maps applied a dichromatic red to green color scheme. This is to better distinguish the difference between the municipalities and readily identify municipalities that need intervention. Having five intervals, two classes are in the shades of red, two are in the shades of green and one that is in the middle uses the shade of light yellow. The gray color is used to portray an area without data/missing data.

The two intervals of 0-49 percent and 50-99 percent use the shades of green, using a darker shade of green for 0-49 percent and a lighter shade of green for 50-99 percent. Thus, a darker shade of green portrays the best situation as compared to the other municipalities of the province. The light yellow shade is portrayed with the values 100-149 percent. This range is within the provincial index of 100, meaning indexes less than 100 percent indicates a better situation than the overall performance of the province. Those indexes that have a higher value than 100 percent indicate a worse situation than the provincial performance. Two intervals are used for this, the 150-199 percent and the 200 percent and over interval. These last two intervals use the shades of red that portrays a worse situation or an alarming performance of the municipality. The darker shade of red is used for the 200 percent and above interval so that it would give the viewer an instant picture of which area has an alarming situation or has the worst situation among the municipalities within the province.
