TL3/NUTS3 region urbanisation typology

Classifies TL3 (NUTS3-equivalent) regions by their access to cities, per the OECD regional urban/rural typology. Supplied by the OECD alongside the original Stata package (Stata/tl3_typology.dta); bundled here as-is because it is small, non-confidential reference data (not firm microdata). Used by build_accounts_indicators() to derive typology_UR when the raw input data has a region_3d column.

Usage

tl3_typology

Format

A data frame with 2,598 rows and 8 columns:

iso3

3-letter ISO country code.

region_3d

TL3/NUTS3 region code — the join key used by build_accounts_indicators().

classificationlatesttl2021

TL classification vintage.

tl

Territorial level (always "3" in this table).

regionalnameeng

Region name (English).

regionalnamepublicationeng

Region name with country/state suffix.

typology_access_cities

5-letter urbanisation code (MR-L, MR-M, NMR-M, NMR-S, NMR-R) — the column build_accounts_indicators() actually reads and remaps to readable labels.

typology_UR

An OECD-supplied labelled urban/rural code, unused by this package (which derives its own typology_UR from typology_access_cities instead — see Pseudocode/n0_1_accounts_indicators_v2.md step 18).
