Spatiotemporal Analysis of the Proportion of Unimproved Drinking Water Sources in Rural Ethiopia: Evidence from Ethiopian Socioeconomic Surveys (2011 to 2019)

Figure 5

Test of spatial autocorrelation of rural unimproved drinking water sources in Ethiopia among households per EAs evidence from ESS data in four waves, 2011/12, 2013/14, 2015/16, and 2018/19. The broken red line on the right side of the figures indicates a high cluster pattern of unimproved drinking water sources at the first, third, and fourth waves of ESS data. Outputs were automatically generated in the upper left and upper right corners of the graph, and it explains that the probability of random clustering patterns is less than 1% except the second wave. (a) Autocorrelation of ESS-wave 1, (b) autocorrelation of ESS-wave 2, (c) autocorrelation of ESS-wave 3, and (d) autocorrelation of ESS-wave 4.
