Question
For the country of Vietnam, what is the statistical geographic hierarchy? What are the Data Buffet geo code patterns at each level? What are the pertinent redefinitions?
Answer
Types of administrative division
- Country (IVNM)
- First-tier divisions (IVNM_^^^):
- Province
- Municipality / independent city
- Second-tier divisions:
- District / rural district
- Urban district
- District-level town
- Provincial city
- Third-tier divisions:
- Ward
- Commune
- Commune-level town / township / townlet
Types of statistical geography
Group of macroregions (IVNM_^^^^)- Region / macroregion (IVNM_^^)
- Metro area (IVNM_M^^^)
- Macroregion excl. metro area (IVNM_^^XH)
UPDATE, January 2020: The geo level "macroregion" is more commonly labeled "region," including in our "geo change" articles. The geo level "group of macroregions" was a misapprehension on our part; such composites are also macroregions. We have redefined their geo codes from IVNM_^^^^ to IVNM_^^ (see identities below) and renamed existing series.
Additive identities
In this table only, "macroregion" is abbreviated "m.r."

| Central m.r. |
|
North Central Coast, South Central Coast, Central Highlands |
IVNM_NC+IVNM_SC+IVNM_MR |
| Southern m.r. |
|
Southeast, Mekong River Delta |
IVNM_SO+IVNM_MR |
| North Central and Central Coast m.r. |
|
North Central Coast, South Central Coast |
IVNM_NCCS IVNM_CC = IVNM_NC+IVNM_SC |
| Northern Midlands and Mountain Area m.r. |
|
Northeast, Northwest |
IVNM_NMMA IVNM_MM = IVNM_NE+IVNM_NW |
We have observed that the annual population figures for province/country are closely additive. For province/region and region/country, however, there is a discontinuity in additivity: it holds from 2008, but prior to that is only approximate. This implies a change (improvement) in procedures at the GSO.
UPDATE, January 2020: We have renamed the geo codes for the macroregions "Red River Delta" and "Southeast."
Changes to administrative divisions
- 2004: Dien Bien (IVNM_DIB) is carved out of Lai Chau (IVNM_LAI), with 55% of the population.
- 2004: Dac Nong (IVNM_DAN) is carved out of Dac Lak (IVNM_DAK), with 20% of the population.
- 2004: Hau Giang (IVNM_HUG) is carved out of Can Tho (IVNM_CAT), with 40% of the population. Can Tho is the fourth-largest city in the country.
- 2008: Ha Tay (IVNM_HAT) is subsumed into Ha Noi (IVNM_HAN), increasing its population by 85%.
Changes in reporting areas
Reporting by eight macroregions (group of provinces) was changed to four macroregions plus two group-of-macroregions. The new system is used as of:
2008: Population2014, retroactive to 2005: Unemployment2015: CPI
