Time Spent Collecting Water. Figure 2 illustrates the most current measures of time spent collecting water (the proportion of households spending 30 or more minutes collecting water) and the annual rate of change of this measure for the study cities. The cities are ranked bottom to top from most desirable access to poorest access. The colored oval on the right of each bar indicates the annual rate of change, measured in percentage points, for each city. The color of the oval indicates positive (green), negative (red), or minimal change (yellow). See Table S2 for complete data.
