Summary On the evening of July 8, 2000, Miyake-jima erupted. The island’s first eruptions in 17 years continued intermittently after that, with the largest eruption at about 17:30 on August 18; low-temperature, sluggish pyroclastic flows occurred on the 29th. This led to an off-island evacuation order on September 1, the evacuation of residents off the island from the 2nd to the 4th in response, and then long-term living in evacuation facilities for over 4 years due to volcanic gas emissions. The damage directly after a disaster tends to attract the most attention, but inevitably, various problems in daily life arise from individual circumstances, and disparity in recovery occur in the process of recovery from disaster. This survey gathers island residents’ voices in the recovery process and reveals the true state of daily life problems and disparity in recovery that occur therein.

This survey was conducted following two previous surveys: the survey conducted in April 2005 immediately after the return to the island (SSJDA survey number 0590) and the second survey in April 2006 (SSJDA survey number 0591).

This survey aims to gain knowledge about residents’ attitudes and problems two years after returning to the island to provide basic data for the ongoing recovery of Miyake Village, as well as sharing the actual situation with the society.

The main survey items are the state of return to Miyake-jima, household budget, and the state of recovery.
Data Type quantitative research: micro data
Universe Heads of households aged 20 years and older or those in a similar position in all households that had returned to Miyake-jima as of April 20 to 24, 2007.
Unit of Observation Individual
Sample Size Valid responses: 520 people

*According to the Miyake Village returnee household confirmation survey, the number of returnee households stands at 1,247 (of which 15 are households of foreign nationals) as of September 2, 2005. The response rate based on this is 41.7%.

Our research (as of April 24) estimates that 1,245 households have returned. This is approximately equal to the number of returnee households surveyed by Miyake Village. However, there were many residences where we could not determine whether the residents had returned and were living there. We included these as well when counting our estimate. The response rate based on the estimated number of returnee households is 41.8%.
