Suicide has become a serious and growing public health problem in Korea. This study is to explore the features of the Korean suicide mortality. For this purpose, we explore two types of data, micro data set and the summary data set for deaths and mortality rates. First, we look at the trends of the suicide rate and the factors of suicide from a variety of perspectives. We then explore the features of the suicide based on the examination, and suggest policy implications focusing on three viewpoints to reduce the suicide rate in Korea. Data exploration results show that the suicide rates have continually increased over the last 25 years since the late 1980s in Korea, and the rates for the age group over 60 were considerably higher than the rates for other age groups since the 2000s. Especially, the rates were overwhelmingly high in the age group of 70 and over 80 in both gender. There is also a seasonality in the suicides. The suicide deaths were high during the spring season, low during the winter season, and high in the days after two main holidays. In addition, the suicides is closely related to the problems of mental/psychiatric and economics.
