# Angola - Risk Assessment Indicators

**Publisher:** HeiGIT (Heidelberg Institute for Geoinformation Technology) · **Source:** [HDX](https://data.humdata.org/dataset/angola---risk-assessment-indicators) · **License:** `cc-by-sa` · **Updated:** 2026-04-13

## Abstract

This dataset provides comprehensive **Risk Assessment Indicators** for **Angola**, aggregated at **admin level 2** and 
can in particular be used to perform a structured risk assessment for **flood** hazards.
It includes demographic, environmental, infrastructure, accessibility, and hazard-related data to support disaster risk and resilience analysis.

All layers are derived from [HeiGIT’s GAIA Pipeline](https://giscience.github.io/gis-training-resource-center/content/GIS_AA/en_gaia_indicators_processing.html), integrating open data sources such as [WorldPop](https://www.worldpop.org/), 
[OpenStreetMap](https://www.openstreetmap.org/), and [Google Earth Engine](https://earthengine.google.com/) based on 
[HDX COD-AB](https://data.humdata.org/dataset/?q=cod-ab) boundaries.

### **Indicator Descriptions**

#### **Access to Services (`AGO_ADM2_access`)**
Represents the share of the population with access to key facilities within defined distances or travel times.

- **ADM2_PCODE** – Administrative division code (ADM2)
- **access_pop_education_5km / 10km / 20km** – Population within 5, 10, and 20 km of educational facilities
- **access_pop_hospitals_30min / 1h / 2h** – Population within 30 minutes, 1 hour, and 2 hours of a hospital
- **access_pop_primary_healthcare_30min / 1h / 2h** – Population within 30 minutes, 1 hour, and 2 hours of a primary health care facility

Data Source: [openrouteservice (ORS)](https://openrouteservice.org/)

---

#### **Facilities (`AGO_ADM2_facilities`)**
Counts of essential service facilities within each district.

- **ADM2_PCODE** – Administrative division code (ADM2)
- **education_count** – Number of educational facilities
- **hospitals_count** – Number of hospitals
- **primary_healthcare_count** – Number of primary health care facilities

Data Source: [OpenStreetMap (OSM)](https://www.openstreetmap.org)

---

#### **Coping Capacity (`AGO_ADM2_coping`)**
Combines **Access to Services** and **Facilities** data to represent a district’s coping capacity.

---

#### **Demographics (`AGO_ADM2_demographics`)**
Shows the population composition by age and gender.

- **ADM2_PCODE** – Administrative division code (ADM2)
- **female_pop** – Total female population
- **children_u5** – Population under 5 years old
- **female_u5** – Female population under 5 years old
- **elderly** – Population aged 65 and older
- **pop_u15** – Population under 15 years old
- **female_u15** – Female population under 15 years old

Data Source: [Worldpop](https://www.worldpop.org/)

---

#### **Rural Population (`AGO_ADM2_rural_population`)**
Same demographic breakdown as above, but limited to rural populations. Rural areas are those outside urban extents,
typically characterized by lower population density, agricultural or natural land use, and limited infrastructure compared to urban centers.

- **ADM2_PCODE** – Administrative division code (ADM2)
- **female_pop_rural**, **children_u5_rural**, **female_u5_rural**, **elderly_rural**, **pop_u15_rural**, **female_u15_rural** – Rural demographic counts
- **rural_pop_perc** – Percentage of total population living in rural areas

Data Source: [Global Human Settlement Layer (GHSL)](https://human-settlement.emergency.copernicus.eu/datasets.php)

---

#### **Vulnerability (`AGO_ADM2_vulnerability`)**
Combines **Demographics** and **Rural Population** indicators.

---

#### **Flood Exposure (`AGO_ADM2_flood_exposure`)**
Shows population and facility exposure to flooding at 30 cm depth for multiple return periods.

- **ADM2_PCODE** – Administrative division code (ADM2)
- **female_pop_30cm**, **children_u5_30cm**, **female_u5_30cm**, **elderly_30cm**, **pop_u15_30cm**, **female_u15_30cm** – Exposed population by group
- **education_30cm_pct / count**, **hospitals_30cm_pct / count**, **primary_healthcare_30cm_pct / count** – Facility exposure (percentage and count)

### **QGIS Plugin Risk Assessment Inputs**

- **Coping Capacity** = Access + Facilities  
- **Vulnerability** = Demographics + Rural Population  
- **Exposure** = Vulnerable Population + Facilities exposed to Floods

## 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 HeiGIT (Heidelberg Institute for Geoinformation Technology) 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/angola---risk-assessment-indicators) for the publisher's own methodology notes and caveats.
