Each row in this dataset represents first-level administrative unit observations. Data was last updated on HDX on 2025-02-07. Geographic scope: COG.

Curated into ML-ready Parquet format by Electric Sheep Africa.

Variables

Geographic — gho_display (Mean BMI (kg/m²) (crude estimate), Alcohol, recorded per capita (15+) consumption (in litres of pure alcohol), Adolescent mortality rate (per 1 000 age specific cohort)), year_display (range 1961.0–2025.0), startyear (range 1961.0–2025.0), endyear (range 1961.0–2025.0), region_code (AFR, #region+code) and 4 others.

Outcome / Measurement — value (No data, No, Yes).

Identifier / Metadata — gho_code (NCD_BMI_MEANC, SA_0000001400_ARCHIVED, CHILDMORT10TO19), dimension_code (SEX_FMLE, SEX_MLE, SEX_BTSX), dimension_name (Female, Male, Both sexes), esa_source, esa_processed.

Other — numeric (range 0.0–3564489366.0), low (range 0.0–820000.0), high (range 0.0–2068000.0).

Curation

Raw data was downloaded from HDX via the CKAN API and converted to Parquet. Column names were lowercased and standardised to snake_case. Common missing-value markers (N/A, null, none, -, unknown, no data, #N/A) were unified to NaN. 1 column(s) with >80% missing values were removed: gho_url. 35 exact duplicate rows were removed. 6 column(s) were cast from string to numeric or datetime based on parse-success rate (>85% threshold). The dataset was split 80/20 into train and test partitions using a fixed random seed (42) and saved as Snappy-compressed Parquet.

Limitations

• Data originates from World Health Organization and has not been independently validated by ESA.
• Automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
• The following columns have >20% missing values and should be treated with caution in modelling: dimension_name, numeric, low, high.
• Refer to the original HDX dataset page for the publisher's own methodology notes and caveats.
