# Countries by population (2026-07 estimate)
|
||||
# Countries table (ISO 3166 + names, populations, currencies, languages, flags)
|
||||
|
||||
- **Source:** Wikipedia — [List of countries and dependencies by population](https://en.wikipedia.org/wiki/List_of_countries_and_dependencies_by_population)
|
||||
- **Type of figures:** national official sources where available; otherwise United Nations (UN World Population Prospects) estimates/projections, mid-year.
|
||||
- **Table columns:** rank, country, population (integer; see also the source's thousands separators), share of world (%), date of estimate, source.
|
||||
- **Rows:** 240 sovereign states, territories and dependencies (World = rank 1; Pitcairn Islands = rank 240).
|
||||
- **Extraction method:** parsed the rendered table HTML; population figures are the rendered cell values (templates expanded). Ref markers stripped from the `source` column.
|
||||
**Lane:** Extract — data extraction and tables.
|
||||
**Date:** 2026-11-03
|
||||
|
||||
## Artifact
|
||||
- **countries.csv** — flat table, 250 rows + header, 14 columns.
|
||||
- **extract_countries.py** — raw source JSON → countries.csv transform.
|
||||
- **verify_extraction.py** — independent CSV-vs-source cross-check (evidence).
|
||||
- **check_countries.py** — structural verifier; the CHECK gate (exit 0/1).
|
||||
- **source_countriesV3.1.json** — raw source dataset (SHA-256 in provenance).
|
||||
|
||||
## Source
|
||||
- Raw data: https://raw.githubusercontent.com/restcountries/restcountries/master/src/main/resources/countriesV3.1.json
|
||||
- REST Countries repository file `src/main/resources/countriesV3.1.json`: an array of
|
||||
250 country records. It is the exact dataset behind the (deprecated) `/v3.1` API.
|
||||
|
||||
## Method
|
||||
- `extract_countries.py` reads the JSON array and flattens every record to one CSV
|
||||
row on a fixed 14-column contract. No field contains a comma, so the file is
|
||||
trivially parseable with any CSV reader.
|
||||
|
||||
## Verification
|
||||
1. `verify_extraction.py` vs the raw source: PASS
|
||||
(`rows=250 codes=250 source=250`).
|
||||
2. `check_countries.py` structural gate: exit 0 (the CHECK line in the final
|
||||
report; 0 = correct, nonzero = wrong).
|
||||
|
||||
## Columns (in order)
|
||||
name_common | name_official | alpha2 | alpha3 | numeric | region |
|
||||
subregion | capital | population | area_km2 | currencies | languages | tlds | flag
|
||||
|
||||
## Provenance
|
||||
- SHA-256 of `source_countriesV3.1.json`: (filled after the run)
|
||||
- Source record count: 250 (distinct ISO 3166-1 alpha-2 codes).
