The totals from the second survey were likely a considerable underestimate as several groups were not included. The 100,000 migrant workers who were collecting the rice harvest, families who were completely wiped out by the storm and those who had migrated out of the region in the three months were not included. Excluding these groups reduced the risk of hearsay and exaggeration. The survey concluded that the overall death toll was, at minimum, 224,000. The worst effects were felt in Tazumuddin, where the mortality was 46.3%, corresponding to approximately 77,000 deaths in Thana alone. The mean mortality throughout the affected region was 16.5%.
