Contains data from the FAOSTAT [bulk data service](https://fenixservices.fao.org/faostat/static/bulkdownloads/datasets_E.json) covering the following categories: Consumer Price Indices, Deflators, Exchange rates, Producer Prices Each row in this dataset represents country-level aggregates. Temporal coverage is indicated by the `startdate`, `enddate` column(s). Geographic scope: **TZA**. *Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).* --- ## Dataset Characteristics | | | |---|---| | **Domain** | Food security and nutrition | | **Unit of observation** | Country-level aggregates | | **Rows (total)** | 438 | | **Columns** | 17 (6 numeric, 9 categorical, 2 datetime) | | **Train split** | 350 rows | | **Test split** | 87 rows | | **Geographic scope** | TZA | | **Publisher** | Food and Agriculture Organization (FAO) of the United Nations | | **HDX last updated** | 2026-04-06 | --- ## Variables **Geographic** — `iso3` (TZA), `year_code` (range 1970.0–2024.0), `year` (range 1970.0–2024.0). **Temporal** — `startdate`, `enddate`. **Outcome / Measurement** — `value` (range 0.0566–252.2274). **Identifier / Metadata** — `area_code` (range 215.0–215.0), `area_code_m49` ('834), `item_code` (range 22024.0–22028.0), `element_code` (range 6179.0–62250.0), `esa_source` (HDX) and 1 others. **Other** — `area` (United Republic of Tanzania), `item` (GDP Deflator, Gross Fixed Capital Formation Deflator, Value Added Deflator (Agriculture, forestry and fishery)), `element` (Value Standard Local Currency, 2015 prices, Value US$, 2015 prices), `unit` (SLC, USD), `flag` (X, E). --- ## Quick Start ```python from datasets import load_dataset ds = load_dataset("electricsheepafrica/africa-faostat-food-prices-for-united-republic-of-tanzania") train = ds["train"].to_pandas() test = ds["test"].to_pandas() print(train.shape) train.head() ``` --- ## Schema | Column | Type | Null % | Range / Sample Values | |---|---|---|---| | `iso3` | object | 0.0% | TZA | | `startdate` | datetime64[ns] | 0.0% | | | `enddate` | datetime64[ns] | 0.0% | | | `area_code` | int64 | 0.0% | 215.0 – 215.0 (mean 215.0) | | `area_code_m49` | object | 0.0% | '834 | | `area` | object | 0.0% | United Republic of Tanzania | | `item_code` | int64 | 0.0% | 22024.0 – 22028.0 (mean 22025.7397) | | `item` | object | 0.0% | GDP Deflator, Gross Fixed Capital Formation Deflator, Value Added Deflator (Agriculture, forestry and fishery) | | `element_code` | int64 | 0.0% | 6179.0 – 62250.0 (mean 34214.5) | | `element` | object | 0.0% | Value Standard Local Currency, 2015 prices, Value US$, 2015 prices | | `year_code` | int64 | 0.0% | 1970.0 – 2024.0 (mean 1996.8767) | | `year` | int64 | 0.0% | 1970.0 – 2024.0 (mean 1996.8767) | | `unit` | object | 0.0% | SLC, USD | | `value` | float64 | 0.0% | 0.0566 – 252.2274 (mean 60.4233) | | `flag` | object | 0.0% | X, E | | `esa_source` | object | 0.0% | HDX | | `esa_processed` | object | 0.0% | 2026-04-08 | --- ## Numeric Summary | Column | Min | Max | Mean | Median | |---|---|---|---|---| | `area_code` | 215.0 | 215.0 | 215.0 | 215.0 | | `item_code` | 22024.0 | 22028.0 | 22025.7397 | 22025.0 | | `element_code` | 6179.0 | 62250.0 | 34214.5 | 34214.5 | | `year_code` | 1970.0 | 2024.0 | 1996.8767 | 1997.0 | | `year` | 1970.0 | 2024.0 | 1996.8767 | 1997.0 | | `value` | 0.0566 | 252.2274 | 60.4233 | 61.7426 | --- ## 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 Food and Agriculture Organization (FAO) of the United Nations 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](https://data.humdata.org/dataset/faostat-food-prices-for-united-republic-of-tanzania) for the publisher's own methodology notes and caveats. --- ## Citation ```bibtex @dataset{hdx_africa_faostat_food_prices_for_united_republic_of_tanzania, title = {United Republic of Tanzania - Food Prices}, author = {Food and Agriculture Organization (FAO) of the United Nations}, year = {2026}, url = {https://data.humdata.org/dataset/faostat-food-prices-for-united-republic-of-tanzania}, note = {Repackaged for machine learning by Electric Sheep Africa (https://huggingface.co/electricsheepafrica)} } ``` --- *[Electric Sheep Africa](https://huggingface.co/electricsheepafrica) — Africa's ML dataset infrastructure.
