Dataset Description

This dataset contains country-level observations for the WHO GHO indicator "Polio (Pol3) immunization coverage among 1-year-olds (%)" (WHS4_544) across African nations, spanning 2000–2024. It is part of the Electric Sheep Africa collection — a unified, ML-ready repository of African data.

Data is sourced directly from the WHO Global Health Observatory OData API and repackaged as Parquet files with a consistent schema. All values are drawn from NumericValue (the float-precision field), not the display string. Confidence interval bounds (value_low, value_high) are included where available.

Coverage

Countries	47 African nations
Years	2000 – 2024
Total rows	1,164
Region filter	WHO AFRO (ParentLocationCode = 'AFR')

Countries included: AGO, BDI, BEN, BFA, BWA, CAF, CIV, CMR, COD, COG, COM, CPV, DZA, ERI, ETH, GAB, GHA, GIN, GMB, GNB … and 27 more

Sub-dimensions

No sub-dimensions (single value per country/year)

When an indicator is stratified (e.g., by sex or age group), each unique combination of country × year × dimension produces a separate row. Filter on dim1 / dim2 for the stratum you need, or aggregate across strata.

Usage

from datasets import load_dataset

ds = load_dataset("electricsheepafrica/africa-who-polio-immunization-coverage-among-1-year-olds")
df = ds["train"].to_pandas()

# Both-sexes, national level only
national = df[df.get("dim1", "").str.endswith("_BTSX") | df.get("dim1", pd.Series()).isna()]

# Time series for one country
kenya = df[df["country_iso3"] == "KEN"].sort_values("year")
