I attempted to compile an accurate long-term panel data by conducting an Internet survey in order to correlate it with the administrative data and life events such as marriage, child bearing, and living with parents that it was thought that memorized surely. This paper shows that the Internet survey method is very effective for compiling panel data and further, it analyzes income disparity and behavior of people who were born in the 1950s. The analysis shows not only the well-known behavior of all generations but also special tendencies of the 1950s generation. : 186-8601 2-1.
