+# Economic Impact of COVID-19 in Sub-Saharan Africa
+
+**Publisher:** Mobile Accord, Inc. (GeoPoll) · **Source:** [HDX](https://data.humdata.org/dataset/economic-impact-of-covid-19-in-sub-saharan-africa) · **License:** `cc-by` · **Updated:** 2025-09-26

+
+## Abstract
+
+This data looks at the impact of COVID-19 on employment, income, ability to pay expenses, and more in Côte D'Ivoire, Kenya, Mozambique Nigeria, and South Africa. Data is nationally representative by age, gender, and location, and is broken down by job type and formal or informal workers. Please contact us for data broken down by province or more information on the methodology.
+
+Each row in this dataset represents country-level aggregates. Data was last updated on HDX on 2025-09-26. Geographic scope: **CIV, KEN, MOZ, NGA, ZAF**.
+
+*Curated into ML-ready Parquet format by [Electric Sheep Africa](https://huggingface.co/electricsheepafrica).*

+## Variables
+
+**Geographic** — `country` (Ivory Coast (Cote D'Ivoire), Kenya, South Africa), `employmenttype` (Unemployed, Employed full time, Student), `jobtype` (Educator, Small business owner/employee, Large business), `informal_work_type` (Seller, Agriculture, Other), `monthlyincome` (0-100000, 0-150000, 0-15000) and 11 others.
+
+**Demographic** — `age_group` (36+, 26-35, 18-25), `gender` (Male, Female).
+
+**Outcome / Measurement** — `incomechange`.
+
+**Identifier / Metadata** — `aid`, `covidloans`, `esa_source`, `esa_processed`.
+
+**Other** — `informalworker` (Yes, No, Not sure), `jobloss` (Yes, No-I’m still able to work, Prefer not to say), `jobregain` (Yes, Don't know, No), `lengthsurvival`.

+## 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`. 8 column(s) with >80% missing values were removed: `otherjob`, `aidsource_aid_organisations`, `aidsource_charities_donations`, `aidsource_friends_family`, `aidsource_government`, `aidsource_not_sure`.... 74 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: `jobtype`, `informalworker`, `informal_work_type`, `jobloss`, `jobregain`, `monthlyincome`, `monthlyincome_bracket`, `incomechange`....
+- This dataset spans 5 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/economic-impact-of-covid-19-in-sub-saharan-africa) for the publisher's own methodology notes and caveats.
