Nigeria - Risk Assessment Indicators

Publisher: HeiGIT (Heidelberg Institute for Geoinformation Technology) · Source: HDX · License: cc-by-sa · Updated: 2026-04-13

Abstract

This dataset provides comprehensive Risk Assessment Indicators for Nigeria, 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, integrating open data sources such as WorldPop, OpenStreetMap, and Google Earth Engine based on HDX COD-AB boundaries.

Data Overview

  • Access to Services (NGA_ADM2_access)
  • Facilities (NGA_ADM2_facilities)
  • Coping Capacity (NGA_ADM2_coping)
  • Demographics (NGA_ADM2_demographics)
  • Rural Population (NGA_ADM2_rural_population)
  • Vulnerability (NGA_ADM2_vulnerability)
  • Flood Exposure (NGA_ADM2_flood_exposure)

 

 

Indicator Descriptions

Access to Services (NGA_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)

Facilities (NGA_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)

Coping Capacity (NGA_ADM2_coping)

Combines Access to Services and Facilities data to represent a district’s coping capacity.

Demographics (NGA_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

Rural Population (NGA_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)

Vulnerability (NGA_ADM2_vulnerability)

Combines Demographics and Rural Population indicators.

Flood Exposure (NGA_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)

Data Source: The Joint Research Centre (JRC)

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 for the publisher's own methodology notes and caveats.
