文摘来源          Floating population is defined as the population in movement without changing the household registration, and currently it refers typically to the population leaving places of usual residence for outside job seeking. Demographically speaking, the floating population has been widely distributed over China, of very young age structure and low education, and staying outside relatively long. While floating population gives rise to problems like unfavorably influencing rural development, and adding difficulties ...             流动人口是处于一定方向下持续移动的人口。在当前的社会生活中,人们往往把离开常住地出外谋生就业的人口视为流动人口。从人口学方面分析,流动人口分布较广,年龄构成轻,文化程度较低,在外停留时间长。人口流动中存在着影响农村农业发展、增加城市管理难度、侵犯合法权益等问题。解决问题的关键在于各级政府部门要提高对这一战略问题的认识,加强调控和疏导,达到有序、有度,使流动人口为国家做出更大的贡献。 文摘来源          This paper,as a social demography approach,seeks to constitute a theoretical hypothesis of fertility demands structure of the Chinese peasants, in which fertility demands are examined in two aspects: fertility,motivation (why) and fertility preferences (what, how and how many).
