Statistical Information Network (tjcn.org) Review: Your Go-To Archive for Hard-to-Find Statistical Yearbooks

1. The "Broken Link" Nightmare for Researchers

Zhang, a grad student, was researching the "Economic Development of Northern Jiangsu Counties" over the last 15 years.
When he visited the official county government website, the data only went back to 2018. All links prior to that were 404 Not Found.
"The website was revamped, and the old data is gone. What now?"

His professor pointed him to tjcn.org (China Statistical Information Network).
Although the site looks like a relic from 2005, he managed to find the full text of the 2009 Statistical Bulletin for that specific county.
"It's like a digital museum for lost data!"

2. Why Use an Unofficial Site?

While not a government agency, TJCN plays two critical roles in the data ecosystem:

1. The "Data Shelter" for History
   The official National Bureau of Statistics (NBS) keeps macro and provincial data perfectly. However, city and county-level data is scattered across thousands of local websites, which are notorious for deleting old files during updates. TJCN archives these text bulletins.

2. The Statistical Yearbook Hub
   Finding the "China Statistical Yearbook" is easy. But finding the "Chengdu Statistical Yearbook" or "Jiangyin Statistical Yearbook" from 2012?
   TJCN organizes directories and content for these niche local yearbooks, making it a great starting point for regional studies.

3. How to Mine Data Here?

1. Finding "Statistical Bulletins"

• Path: Home -> Click a province on the map -> Select "Statistical Bulletin" (统计公报).
• Tip: Search directly for "County Name + Year + Bulletin". These documents contain core metrics like local GDP, birth rates, and industrial output.

2. Finding "Statistical Yearbooks"

• Path: Click [Statistical Yearbook] on the top nav.
• Note: Many entries are scanned images or table of contents. If a download link is missing, use the specific yearbook title found here to search on other library databases.

3. Industry Data

• There is a section for specific industries (Textile, Coal, Agriculture), which is useful for historical capacity analysis.

4. Pros and Cons

Feature	Pros	Cons	Advice
Coverage	Massive, down to county level	Updates lag behind official sites	Use for historical data, not current
UI/UX	Dense information	Ugly & Ad-heavy	Use an Ad-blocker
Reliability	Reposted from official sources	Risk of typo/copy errors	Verify key numbers if possible
Cost	Free	None	Good for budget researchers

5. Conclusion

tjcn.org is the "Spare Tire" for data analysts.
You might not use it daily, preferring the shiny official NBS site or expensive terminals like Wind. But when you face the "Official site down / Data deleted / Too old to find" scenarios, this messy, old-school aggregator might just save your thesis.
