It is published as ML-ready Parquet with consistent Hugging Face metadata, source provenance, and analysis-friendly loading examples. ## What This Dataset Measures Official statistics datasets help analysts inspect public data as published by governments, national statistical systems, and regional data portals. Source-provided context: HNO 2017 Sahel - Food Insecurity ## How To Read This Dataset - **One row means:** one source record from the original tabular resource, with Electric Sheep Africa provenance columns added where available. - **Primary geography column:** `country_iso3`. - **Best time column:** `year`. - **Time coverage basis:** year. - **Recommended join keys:** `country_iso3` where available plus source-specific keys. ## Coverage | Dimension | Value | |---|---:| | Rows | 13 | | Countries/areas | 1 | | First period | 2017 | | Last period | 2017 | | Indicators | 0 | | Columns | 22 | | Source format | XLSX | ## Geographic Coverage Top areas shown below, sorted by row count when available: | Area | Rows | First year | Last year | Name | |------|-----:|-----------:|----------:|------| | `TCD` | 13 | 2017 | 2017 | `Chad` | ## Indicators, Variables, Or Resource Contents - This repo preserves one source tabular resource with its usable columns kept together. ## Schema | Column | Type | Description | Example | |--------|------|-------------|---------| | `source_record_id` | `string` | Stable row identifier assigned during Electric Sheep Africa engineering. | `798b6a50-75da-4c8c-8034-4a4439630a3a:sheet1:0` | | `country_iso3` | `dictionary` | ISO3 country or area code. | `TCD` | | `country_name` | `dictionary` | Country or area name. | `Chad` | | `source_sheet` | `string` | Source column from the original resource. | `Sheet1` | | `year` | `int64` | Observation year. | `2017` | | `mali` | `string` | Source column from the original resource. | `Mauritania` | | `severe_food_unsecure` | `string` | Source column from the original resource. | `severe food unsecure` | | `d_495000` | `string` | Source column from the original resource. | `443497` | | `d_495000_2` | `string` | Source column from the original resource. | `-` | | `d_495000_3` | `string` | Source column from the original resource. | `-` | | `d_100` | `string` | Source column from the original resource. | `-` | | `source_period_start_year` | `int64` | Start year inferred from source metadata. | `2017` | | `source_period_end_year` | `int64` | End year inferred from source metadata. | `2017` | | `source_period_label` | `dictionary` | Source column from the original resource. | `2017` | | `source_provider` | `dictionary` | Publishing organization. | `OCHA West and Central Africa (ROWCA)` | | `source_dataset` | `dictionary` | Source dataset or package title. | `Sahel : Humanitarian Needs Overview` | | `source_resource` | `dictionary` | Source resource title, table name, or file name. | `HNO-2017-Sahel-Food Insecurity.xlsx` | | `source_package_id` | `dictionary` | Source package identifier. | `47f6ef46-500f-421a-9fa2-fefd93facf95` | | `source_resource_id` | `dictionary` | Source resource identifier. | `798b6a50-75da-4c8c-8034-4a4439630a3a` | | `source_url` | `dictionary` | Original source URL or download URL. | `https://data.humdata.org/dataset/47f6ef46-500f-421a-9fa2-fefd93facf95...` | | `license_id` | `dictionary` | Source license identifier. | `cc-by` | | `retrieved_at` | `dictionary` | UTC source retrieval timestamp from the Electric Sheep Africa pipeline. | `2026-08-10T22:51:43Z` | ## Usage ```python from datasets import load_dataset ds = load_dataset("electricsheepafrica/africa-chad-sahel-humanitarian-needs-overview-62f1167b") df = ds["train"].to_pandas() print(df.head()) ``` ### Inspect Columns ```python print(df.info()) print(df.head()) ``` ### Filter By Geography ```python if "country_iso3" in df.columns: sample = df[df["country_iso3"] == "TCD"] ``` ### Time-Series Pattern ```python if "value" in df.columns and "year" in df.columns: trend = df.sort_values("year") ``` ### Pivot For Analysis ```python if {"indicator_id", "year", "value"}.issubset(df.columns): matrix = df.pivot_table(index="year", columns="indicator_id", values="value") print(matrix.tail()) ``` ## Data Quality Notes - Canonical time field: `year`. - Missing values are preserved rather than silently imputed. - Column names are standardized for machine use; source meanings are preserved where known. - Always confirm source methodology, units, and collection definitions before policy, production, or redistribution-sensitive use. ## Source And Provenance - **Source:** [OCHA West and Central Africa (ROWCA)](https://data.humdata.org/dataset/sahel-humanitarian-needs-overview) - **Publisher:** OCHA West and Central Africa (ROWCA) - **Portal:** [https://data.humdata.org](https://data.humdata.org) - **Resource:** [HNO-2017-Sahel-Food Insecurity.xlsx](https://data.humdata.org/dataset/47f6ef46-500f-421a-9fa2-fefd93facf95/resource/798b6a50-75da-4c8c-8034-4a4439630a3a/download/hno-2017-sahel-food-insecurity.xlsx) - **License:** [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/) - **Retrieved/generated:** `2026-08-11T01:29:51Z` - **Hugging Face repo:** [electricsheepafrica/africa-chad-sahel-humanitarian-needs-overview-62f1167b](https://huggingface.co/datasets/electricsheepafrica/africa-chad-sahel-humanitarian-needs-overview-62f1167b) ## Transformations Applied - Converted the source table to Parquet for efficient analytics and ML workflows. - Added or preserved source provenance columns where available. - Standardized README metadata, dataset loading configuration, schema documentation, and citation format. - Preserved source-reported values without analytical imputation. ## Suggested Analyses - Profile the distribution of values - Compare categories or geographies - Join with complementary public datasets - Build time-series views and period-over-period comparisons - Check missingness before modeling - Use `country_iso3` as the safest geography join key when present ## Citation ```bibtex @misc{electric_sheep_africa_africa_chad_sahel_humanitarian_needs_overview_62f1167b_2017, title = {Sahel Humanitarian Needs Overview | Africa (OCHA West and Central Africa (ROWCA))}, author = {OCHA West and Central Africa (ROWCA)}, year = {2017}, url = {https://data.humdata.org/dataset/sahel-humanitarian-needs-overview}, publisher = {Hugging Face Datasets, engineered by Electric Sheep Africa}, howpublished = {\url{https://huggingface.co/datasets/electricsheepafrica/africa-chad-sahel-humanitarian-needs-overview-62f1167b}} } ``` ## License Released under [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/).
