The Survey on the estimation of the income of the local communities generated from swallow houses had already been conducted starting from 8th until 18th December 2016. There are 5 villages as mentioned in the scope of works visited with the total of 50 respondents as the target of survey within the District of Sabangau Kuala. However, the 50 respondents targeted were not met. There were only 41 respondents could be interviewed. This was due to the fact that there were many swallow houses newly built and have not been productive yet.
