+# Perceptions and impact of Coronavirus in Sub-Saharan African countries
+
+**Publisher:** Mobile Accord, Inc. (GeoPoll) · **Source:** [HDX](https://data.humdata.org/dataset/covid-19-impacts-africa) · **License:** `cc-by` · **Updated:** 2025-09-26
+
+---
+
+## Abstract
+
+This data and report examine perceptions and the impact of COVID-19 in 12 countries throughout sub-Saharan Africa. Topics covered include greatest concerns surrounding coronavirus, preventative measures being taken, changes in food market operability and food security, consumer behavior changes, and trust in governments to prevent the spread of coronavirus. This dataset includes data from 10 of the markets. Please contact us for access to data from all markets, the questionnaire, and with any other questions.
+
+Each row in this dataset represents first-level administrative unit observations. Temporal coverage is indicated by the `survey_date` column(s). Geographic scope: **BEN, CIV, COD, GHA, KEN, MOZ, NGA, RWA, and 4 others**.
+
+*Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).*

+## 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`. 1 exact duplicate rows were removed. 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 Mobile Accord, Inc. (GeoPoll) and has not been independently validated by ESA.
+- Automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
+- The following columns have >20% missing values and should be treated with caution in modelling: `biggestchallenge`, `foodlocations2`, `brandpurchase`, `socialmedia`, `staypositive`.
+- This dataset spans 12 countries; geographic and methodological inconsistencies across national boundaries may affect cross-country comparability.
+- Refer to the [original HDX dataset page](https://data.humdata.org/dataset/covid-19-impacts-africa) for the publisher's own methodology notes and caveats.
