+# Zimbabwe - Trade
+
+**Publisher:** World Bank Group · **Source:** [HDX](https://data.humdata.org/dataset/world-bank-trade-indicators-for-zimbabwe) · **License:** `cc-by` · **Updated:** 2026-03-27

+
+## Abstract
+
+Contains data from the World Bank's [data portal](http://data.worldbank.org/). There is also a [consolidated country dataset](https://data.humdata.org/dataset/world-bank-combined-indicators-for-zimbabwe) on HDX.
+
+Trade is a key means to fight poverty and achieve the Millennium Development Goals, specifically by improving developing country access to markets, and supporting a rules based, predictable trading system. In cooperation with other international development partners, the World Bank launched the Transparency in Trade Initiative to provide free and easy access to data on country-specific trade policies.
+
+Each row in this dataset represents country-level aggregates. Data was last updated on HDX on 2026-03-27. Geographic scope: **ZWE**.
+
+*Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).*

+| **Domain** | Poverty and economic vulnerability |
+| **Unit of observation** | Country-level aggregates |
+| **Rows (total)** | 4,198 |
+| **Columns** | 8 (2 numeric, 6 categorical, 0 datetime) |
+| **Train split** | 3,358 rows |

+
+## Variables
+
+**Geographic** — `country_name` (Zimbabwe), `country_iso3` (ZWE), `year` (range 1960.0–2024.0).
+
+**Outcome / Measurement** — `value` (range -4402366967.1392–22074260817.5123).
+
+**Identifier / Metadata** — `indicator_name` (Merchandise trade (% of GDP), Merchandise imports (current US$), Merchandise exports (current US$)), `indicator_code` (TG.VAL.TOTL.GD.ZS, TM.VAL.MRCH.CD.WT, TX.VAL.MRCH.CD.WT), `esa_source` (HDX), `esa_processed` (2026-04-11).

+
+## Quick Start
+
+```python
+from datasets import load_dataset
+
+ds    = load_dataset("electricsheepafrica/africa-world-bank-trade-indicators-for-zimbabwe")
+train = ds["train"].to_pandas()
+test  = ds["test"].to_pandas()
+
+print(train.shape)
+train.head()
+```

+## Schema
+
+| Column | Type | Null % | Range / Sample Values |
+|---|---|---|---|
+| `country_name` | object | 0.0% | Zimbabwe |
+| `country_iso3` | object | 0.0% | ZWE |
+| `year` | int64 | 0.0% | 1960.0 – 2024.0 (mean 2001.4474) |
+| `indicator_name` | object | 0.0% | Merchandise trade (% of GDP), Merchandise imports (current US$), Merchandise exports (current US$) |
+| `indicator_code` | object | 0.0% | TG.VAL.TOTL.GD.ZS, TM.VAL.MRCH.CD.WT, TX.VAL.MRCH.CD.WT |
+| `value` | float64 | 0.0% | -4402366967.1392 – 22074260817.5123 (mean 539633016.6936) |
+| `esa_source` | object | 0.0% | HDX |
+| `esa_processed` | object | 0.0% | 2026-04-11 |

+
+## Numeric Summary
+
+| Column | Min | Max | Mean | Median |
+|---|---|---|---|---|
+| `year` | 1960.0 | 2024.0 | 2001.4474 | 2003.0 |
+| `value` | -4402366967.1392 | 22074260817.5123 | 539633016.6936 | 30.0528 |

+
+## 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`. 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 Bank Group 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/world-bank-trade-indicators-for-zimbabwe) for the publisher's own methodology notes and caveats.
