This study tries to resolve problems of aging population as well as low fertility, based on the survey of Dague citizens about attitudes on and causes of low fertility. Following systematic sampling, the survey was conducted among people ages 19 to 44, who are classified to unmarried men/women, and possible pregnancy women, and the sample was chosen in consideration of ages, resident areas, economic activities they are participating in. The survey asked questions about values on marriage and childbearing, attitudes on low fertility, marriage status and number of children. The result shows that negative perception of marriage is on the increase, that women are under unfavorable surroundings, and that marriage and childbearing is great stress. It also shows that low fertility is due to the great financial burden of child-care and education, and that people seldom know about the various childbearing support programs provided by the local government even though they need social and economic help. In conclusion, the government need to provide financial support programs for child-care and childbearing and policies that may help people return to their job after maternity leave.
