Abstract

Data on languages spoken in Angola, showing the main language spoken in the household by proportion of the population. Data is drawn from AfroBarometer. For more resources on the languages of Angola and language use in humanitarian contexts please visit: https://clearglobal.org/language-maps-and-data/

Each row in this dataset represents time-series observations. Temporal coverage is indicated by the datetime_published, date_creation column(s). Geographic scope: AGO.

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

Variables

Geographic — location_code (AGO), location_name (Angola), location_level (range 0.0–0.0), reliability_score (range 0.5607–0.5607), representivity_rating (moderate).

Temporal — datetime_published, date_creation.

Demographic — language_code (port1283, Unknown, kimb1241), language_name (Portuguese, Unknown, Kimbundu), language_rank (range 1.0–11.0).

Outcome / Measurement — proportion_value (range 0.0008–0.8084).

Identifier / Metadata — dataset_name (Angola Round 9 data (2022)), source (AfroBarometer), esa_source (HDX), esa_processed (2026-04-05).

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. 2 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 CLEAR Global (previously Translators without Borders) and has not been independently validated by ESA.
• Automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
• Refer to the original HDX dataset page for the publisher's own methodology notes and caveats.
