Does anyone know where shapefiles for OECD (Organisation for Economic Co-operation and Development) Regions might be found?

The regions are defined in this document:

http://www.oecd.org/regional/regional-policy/42392313.pdf (Warning: ~10MB file)

There is a screenshot from that document showing the regions in Ontario below.

Ideally, what I need is a way to link OECD regional identifiers (like 'CA3560' below) to places on a map I will create in QGIS. Strict boundaries would be nice, but they are not necessary -- geographic long / lat from the centre of each region would also work.

  • Have you tried contacting them? There's an email on the bottom of this page oecd.org/gov/regional-policy/… – Andrew Tice May 17 '15 at 6:53
  • Thanks, Andrew. That will be my next step. But I was hoping it might be easier -- and faster -- than that. I am going to try Detlev's approach and see how that goes. Thanks again! – tgraybam May 17 '15 at 13:26
  • Not a problem, that's why it was a comment! Just as a point, I had a look at the GADM database (gadm.org) and spotted it hadn't been updated since 2012. You might want to compare the current OECD boundaries visually to the GADM ones - admin boundaries have a nasty habit of changing. This could be a bit of a problem if you're attempting any mapping of OECD data in the future. – Andrew Tice May 18 '15 at 1:04
  • Thanks. I hadn't noticed the stale(ish) data in the GADM. I will look closely, though the odd discrepancy won't be an issue for my current project. But it sure might next time. – tgraybam May 18 '15 at 12:42
  • Cool, its the boring, tedious side of GIS work - but it does need doing sometimes! – Andrew Tice May 19 '15 at 22:16

After a fixed time for searching I would use the GADM database, copy&paste the levels and territory names to Excel or Access, and try to join both. ADM levels 2 and 3, depending on the country, seem to provide geometry and names to join with.

  • This is going to work, thanks Detlev! There was more cutting and pasting and general wrangling than I wanted (plus wrestling with unicode). There is a small number of differences between the GADM data (2012 last updated -- thanks Andrew!) and the OECD patent data (2011). This made joining a bit finicky. But it worked in the end. Thanks! – tgraybam May 18 '15 at 12:49
  • I agree with you. Different reference systems, different schemes, and different currentness of data downgrade otherwise fine ETL jobs to copy 'n paste and manual editing. I apologize for the missing info about the latest revision date. But as far as I know GADM is the most complete and freshest free accessible database on administrative boundaries. – Detlev May 18 '15 at 16:36
  • No apologies necessary, of course! You saved my bacon. Thanks again. – tgraybam May 20 '15 at 15:04

Due to the size of the shapefiles, they are not posted in the OECD website. The TL2 and TL3 shapefiles can be found in the following Dropbox link:


The detailed FUAs can be found at the following link:
