+# Rule of law index, 2022 for select African countries
+
+**Publisher:** The Charter Project · **Source:** [OpenAfrica](https://open.africa/dataset/rule-of-law-index-2022-for-select-african-countries) · **License:** `cc-by` · **Updated:** 2023-04-12

+
+## Abstract
+
+The 2022 WJP Rule of Law Index evaluates 140 countries and jurisdictions around the world. For the fifth year in a row, the rule of law has declined in most countries.
+
+Each row in this dataset represents tabular records. Data was last updated on OpenAfrica on 2023-04-12. Geographic scope: **Africa (multiple countries)**.
+
+*Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).*

+## Curation
+
+Raw data was downloaded from OpenAfrica 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`. 53 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 The Charter Project 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://open.africa/dataset/rule-of-law-index-2022-for-select-african-countries) for the publisher's own methodology notes and caveats.
