Section 4 Data Summaries
Below are summary graphs for a sample of indicators8. All estimates are at surveyed household locations (after imputing missing/invalid locations as described in Section 1).

We note from the above charts that NDVI and NDVI Anomaly values should be corrected on the left tail (might want to set all NDVI values below -0.3 to NA). These only affect the last 3 dekads (mostly).
