1 Overview: China Census
• Population Census (every 10 years )2000(5th) , 2010……
• Economic Census (every 5 years )2004(1st),2008,2013……
• Agriculture Census (every 10 years )2007(1st),2017

• In China, The local government and local statistics officials take a more important role in Census
• Census is organized in accordance with administrative divisions: province, city, county/district, town, village/block and enumeration areas(EA)

2 Development of Census Mapping and Use of GIS
• In the 2000 census, most parts of China used hand-drawn census maps, not digital maps, because available maps were too small to provide sufficient details, or considered out of date.
• But in the past 5 years, many cities got high-quality and large-scale maps, by surveying and aerial photography.
![Page 5: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/5.jpg)
• Some city digitizing the census maps and developed local Statistic-Geographic Information Systems
• Census data are linked with spatial data, by adding hand-drawn EA’s boundaries above the new maps as an overlay.

• Usually the local bureau of statistics and their cooperation commercial company develop and manage these systems which are funded by local government
• GIS software: SuperMap, ArcGIS, MapInfo

A Statistic-Geographic Information System of Qingshan District, Baotou City

Census map of Qingshan: buildings, enumeration area’s boundary and POI

The system integrate the data of Population Census, Economic Census and other statistic survey
![Page 10: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/10.jpg)
Users can inquiries and analysis all the local data about population, economy, social problem, with table, graph or thematic map
![Page 11: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/11.jpg)
• We published CD-ROM named as “Annual Electric Maps of National Social and Economic Statistics” since 2004, which is a simple GIS for query at county/district level.
• The map scale is 1:250,000• The attribute data includes statistic data of every
county in the whole country, including population, work, education, industry and so on

3 Problems
• Uniform standard China is a big country, but in very different.
• There is no uniform standard of census mapping in China.
• Some cities have accurate census maps and developed systems , while some have only cursory maps drawn in paper.
![Page 13: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/13.jpg)
• Different areas have different difficulty • In the big city:
Roads and buildings change soon. The expenses of buying large-scale maps and updating are too expensive
• In some area:The local government don’t have enough money to survey, update maps and take digital census mapping
![Page 14: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/14.jpg)
• We are preparing to establish a uniform standard of census mapping, which can be used in all the census and in most areas of China.
• Include: framework, approach, software and so on
• Some areas will be funded
![Page 15: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/15.jpg)
Spatial Data• All the activities about surveying and
mapping are under the supervision of State Bureau of Surveying and Mapping (SBSM) in China
• It’s hard to got spatial data which can be used in census mapping, especially large-scale maps
![Page 16: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/16.jpg)
• We need to cooperate with SBSM to got spatial data. We need more large-scale maps which is updated to support census mapping.
• We will make a more closer cooperation with SBSM. Maybe a standard of basic map elements for census will be established soon.

4 Prospect
• We have a project to construct a platform named as ESSGIS (Economic and Social Statistic GIS), include census mapping, management of the census database, analysis of the data and data dissemination
![Page 18: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/18.jpg)
GPS&PDA used in census
Software for census mapping
ESSGIS
Census data management
Census data analysis
Census data dissemination
![Page 19: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/19.jpg)
We are developing a simple software used in census mapping instead of manual drawing.
![Page 20: Development of Census Mapping and Use of GIS in China Gao Hansong Census Center of National Bureau of Statistics, China 10.2007.](https://reader035.fdocuments.in/reader035/viewer/2022062315/56649ea95503460f94bacdfb/html5/thumbnails/20.jpg)
We are applying for special funds to complete the project .
We will make a trial in the 2008’s China Economic Census
Maybe in 2010 population census……
