据我理解,那些住在工作在城市但是没有城市户口的人可以当作Migrants来处理. 但是匪夷所思的是为什么没有学者用CHNS来学习Migrants? 这么多年的Panel包括了不少Migrants的数据的.

是他们不理解Datasets,还是我理解错了, 还是其他原因?

请问有人吗? 请帮助一下,谢谢.

同问！如果是这个意思的话，这个方面研究是很有价值的

chns数据中农村的占多数，且每年line 大于 20的只有几百个，流动人口太少，数据缺失严重，，因此信息不是太充分吧，

好像错了。21 = first new household member added to the roster in 1991
22 = second new household member added to the roster in 1991, and so on
31 = first new household member added to the roster in 1993
32 = second new household member added to the roster in 1993, and so on
41 = first new household member added to the roster in 1997
42 = second new household member added to the roster in 1997, and so on
61 = first new household member added to the roster in 2000
62 = second new household member added to the roster in 2000, and so on
77 = grandparent
88 = uncle/aunt
99 = other
-2 = guest

For LINE numbers 21, 22, 31, 32, 41, 42, 61, 62, etc., the first digit identifies the round in which the individual first appeared in the Household Member Roster (2=1991, 3=1993, 4 & 5=1997, 6=2000).

LINE numbers 77, 88, and 99 are used in the Childcare section of the Household Survey.

LINE number -2 is used in the Nutrition Survey.
