Github repository with code for the CMGPD Public Release

We created a repository to share the STATA code that processes the original CMGPD data from the Excel spreadsheets produced by our coders and turns it into the working file that is the basis of our analysis and the public release available at ICPSR. This is intended to help users of the data better understand the process by which it went from the spreadsheets transcribed by the coders to the datasets available at ICPSR. The code for linking individuals to their kin may be of particular interest.

Lee-Campbell Group celebrates Xiao Xing’s retirement and contributions


James Lee and Xiao Xing

On December 13, 2019, the Lee-Campbell Group held a dinner in Beijing in honor of Xiao Xing, who retired in 2018 after working with us for 20 years.

Xiao Xing was the first coder we engaged in mainland China in 1998 after we decided to move our data entry there. She helped enter material for many of our databases, including but not limited to the CMGPD-LN, CMGPD-SC and more recently the CGED-Q. She also helped with the training of new coders. Her feedback also played a role in the specification of protocols for data entry.

James Lee, Cameron Campbell, Bijia Chen and our coders in Beijing.

It has been a tremendous pleasure to work with Xiao Xing for two decades. We are grateful for all of her contributions and wish her the best in her retirement.


Paper on interethnic marriage during the Qing designated “Editor’s Choice” by the journal Demographic Research

The paper “Interethnic marriage in Northeast China, 1866-1913” co-authored by current Lee-Campbell group PhD student Bijia Chen, Lee-Campbell group PhD graduate Dong Hao (now an Assistant Professor at Peking University) and Cameron Campbell that was published this year in Demographic Research has been named Editor’s Choice by the journal’s editorial board as one of the best papers published in volume 38. The paper examines patterns of intermarriage between Han and Manchu in a frontier population in northeast China from the mid-19th century to the beginning of the 20th century. It finds that intermarriage between the two groups was not uncommon and also increased over time. The chances of intermarriage depended on village and family context as well as individual socioeconomic and demographic characteristics. The article is available Open Access here:
