China Administrative-Division Data CTAmap 1.12 Version Update

Since 2022, the author has been organizing a long time-series dataset of China's administrative divisions. Based on the National Fundamental Geographic Information vector data, with reference to the administrative-division vector data from Amap (AutoNavi), the Ministry of Civil Affairs, GADM, township boundaries, village boundaries, the standard maps of various provinces, and related textual materials on administrative-division changes, the administrative-division data of each year has been retrospectively derived year by year.

This data is now officially named CTAmap (China Temporal sequence Administrative Map). Considering the previous version update status, the current version number is CTAmap 1.12. Version 1.12 collected feedback from readers and corrected existing issues.

1. Administrative Division of Haihui Town, Lushan City, Jiujiang City, Jiangxi Province

In May 2016, according to the "State Council Approval on Adjusting the Administrative Divisions of Jiujiang City, Jiangxi Province", Haihui Town (6 villages/residents' committees: Haihui, Luxing, Pengshan, Changling, Wuzhou, Guangming, etc.) was transferred to the jurisdiction of Lushan City. In the previous version update, this administrative-division change was missed. Version 1.12 has been corrected, and the corrected years are 2017–2023.

(2) Province Code Error for Putuo District, Shanghai

Version 1.12 has been corrected, and the corrected years are 2013–2023.

(3) Code Issue for Zouping City, Shandong Province

Approved by the Ministry of Civil Affairs on July 2, 2018, published by the Shandong Provincial People's Government on August 28. Zouping County was abolished and the county-level Zouping City was established, with the administrative code changed from 371626 to 371681. Version 1.12 has corrected the code issue.

(4) Administrative-Division Issue of Lubei District, Hebei Province

After comparison and search of information, in 2019, Fengrun District transferred Hancheng Town to Lubei District. This change was not recorded. The 2020–2023 administrative-division data have been repaired.

(5) Issue of the Exclave of Sui County, Hubei Province

In 2000, Suizhou City was abolished, and Suizhou City was renamed Zengdu District. In 2009, part of the townships of Zengdu District were separated to establish Sui County, including this exclave of Zengdu District. This version has repaired this area.

(6) Administrative-Division Issue of Baimasi Town, Luoyang City, Henan Province

In July 2007, the administrative-division adjustment of Luoyang City was made. Magou Village, Langou Village, Lvmiao Village, and Shilipu Village, which were under the jurisdiction of Baimasi Town, Luolong District, were handed over to the Yangwen Subdistrict of Chanhe Hui District for management. Chanhe Hui District has 9 township-level administrative divisions under its jurisdiction, including Chanhe Hui Township, Dongguan Subdistrict, Beiyao Subdistrict, Baimasi Town, and Yangwen Subdistrict. Version 1.12 has been corrected, and the corrected years are 2013–2023.

In addition, in 2022, some villages in Yanshi and Mengjin had their administrative divisions adjusted. The Longhutan Village and Hanqi Village, originally under the jurisdiction of Shouyangshan Subdistrict of Yanshi, and Jincun Village and Zhaiquan Village, originally under the jurisdiction of Pingle Town of Mengjin, are transferred to the jurisdiction of Baimasi Town, Chanhe District.

Therefore, the early-2023 administrative-division data for this area is different from the previous years, and the modifications are as follows:

(7) Administrative-Division Issue of Honggutan District, Nanchang City, Jiangxi Province

On December 24, 2021, with the approval of the Jiangxi Provincial Government, Houtian Township of Xinjian District, Nanchang City was transferred to the jurisdiction of Honggutan District. On August 6, 2022, Liuhu Town of Xinjian District, Nanchang City was transferred to the jurisdiction of Honggutan District. In the original version of the early 2023 county-level data, Honggutan District was missing Houtian Township, which has been corrected.

Other Issues

Other issues have also been corrected. For example, the field type of the administrative-division code was changed from numerical to text; the administrative-division boundaries of some regions were modified, etc.
