A tibble of the 194 World Health Organization (WHO) Member States, with standard country identifiers and WHO/Pacific groupings used across DSIR analytical workflows.

Usage

who_countries

Format

A tibble with 194 rows and 8 columns:

iso3

ISO 3166-1 alpha-3 code (3-letter, e.g. "PHL").

iso2

ISO 3166-1 alpha-2 code (2-letter, e.g. "PH").

m49_code

UN M49 numeric code, stored as a 3-character string with leading zeros where present (e.g. "008" for Albania). Stored as character because some downstream APIs (notably the UN SDG API) expect the leading-zero form.

name_official

WHO official English name (e.g. "Iran (Islamic Republic of)"). Use for formal documents and reports.

name_short

A shorter form suitable for charts and tables (e.g. "Iran"). Equal to name_official for countries whose official name is already concise. See Details.

who_region

WHO region code: one of "AFR", "AMR", "SEAR", "EUR", "EMR", "WPR".

is_pic

Logical. TRUE for the 14 Pacific Island Country (PIC) Member States in WPR, FALSE otherwise.

wb_income_group

World Bank income classification: "High income", "Upper middle income", "Lower middle income", or "Low income". NA for Cook Islands and Niue, which are not World Bank economies. See Details for the vintage.

Details

Scope. WHO has 194 Member States plus 2 Associate Members (Puerto Rico, Tokelau) and reports on additional non-Member areas (e.g. West Bank and Gaza Strip). This dataset includes only the 194 Member States. Cook Islands and Niue are full WHO Member States and are included even though they are not UN member states.

Region coverage (as of May 2025, after WHO EB156 reassignment of Indonesia from SEAR to WPR):

  • AFR (African Region): 47

  • AMR (Region of the Americas): 35

  • SEAR (South-East Asia Region): 10

  • EUR (European Region): 53

  • EMR (Eastern Mediterranean Region): 21

  • WPR (Western Pacific Region): 28

Short names. name_short differs from name_official for 13 countries where the official name is a parenthetical descriptor or is otherwise long. Examples: "DPR Korea", "DR Congo", "Lao PDR", "United Kingdom". These short forms follow conventions used in WHO regional reports and OECD Health at a Glance: Asia/Pacific.

PICs. The Pacific Island Countries flag (is_pic) marks the 14 WHO Member States in the Pacific sub-region: Cook Islands, Fiji, Kiribati, Marshall Islands, Micronesia (Federated States of), Nauru, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga, Tuvalu, and Vanuatu. Non-Member Pacific areas (e.g. New Caledonia, French Polynesia, American Samoa) are not included in this dataset.

Income groups. wb_income_group carries the World Bank classification of fiscal year 2027 (released 1 July 2026; based on 2025 GNI per capita, Atlas method). The classification is revised every 1 July, so this column reflects the vintage current at the package release date — for a historical vintage (e.g. reproducing an older analysis), join your own copy of the World Bank OGHIST table instead. Cook Islands and Niue are WHO Member States but not World Bank economies and are NA.
