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 is the second survey, conducted following the previous year’s survey immediately after the return to the island (conducted in April 2005) (SSJDA survey number 0590).

This survey aims to gain knowledge about residents’ attitudes and problems one year after returning to the island to provide the basic materials to understand the ongoing recovery of Miyake Village, as well as sharing the actual situation with the public.

The main survey items are the state of return to Miyake-jima, household budget, and recovery.
Data Type quantatitive research
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 25, 2006
Unit of Observation Individual
Sample Size Valid responses: 489 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 39.2%.

Our research (as of April 25) estimates that 1,079 households have returned (including residences where we could not determine whether the residents had returned and were in residence), giving a response rate of 45.3%. The reason that this figure is less than the number of households in the Miyake Village returnee household confirmation survey is that we did not include temporary transfers from the mainland in the survey samples.
