Montserrado Flood Susceptibility & Population Context Dashboard

An interactive analytical tool combining CRAF's relative flood-susceptibility screening surface with official LISGIS 2022 community population and household totals. Module 01 provides coordinated views of physical susceptibility, estimated population and household distribution in High and Very High susceptibility areas, waterways, and rainfall context.

Analytical scopeMontserrado County 266 communities · 15 census units · 90 m allocation grid
Population · 20221,920,965Official LISGIS total
Households · 2022592,787Official LISGIS total
Estimated population in High + Very High areas1,768,42792.1% of county population
Estimated households in High + Very High areas549,38292.7% of county households

Estimated youth age 15–35781,412County youth share applied to the modeled population in High + Very High areas
Allocation sensitivity range1,763,536–1,773,365Tests settlement-weight assumptions only; not a full confidence interval
Communities modeled266Official LISGIS community / clan polygons
Interpretation: The figures shown for High and Very High areas are model-based screening estimates of where population or households may be located relative to the susceptibility surface. They do not mean that every person or household shown has experienced flooding, and the susceptibility classes are not flood probabilities.

Interactive Map Views

Physical flood susceptibility

View the county-relative physical susceptibility surface produced from the six-factor screening model.

Map meaning: the physical susceptibility surface shows county-relative screening classes. These classes are not flood probabilities.

Statistical Views

Modeled population and households by susceptibility class, sex and census unit

These charts show model-based allocations of official 2022 totals across susceptibility classes. The rainfall series remains a separate physical-context indicator.

Community Statistics

Explore Montserrado communities

Select a census unit or township first. The Community list will then show the communities recorded under that area. Select a community to view its statistics and highlight it on the map.

Community Statistics

Interpretation: High/Very High figures are model-based screening estimates of population or households located within the relative susceptibility surface. They are not observed flood-affected counts and should be validated with local flood history and finer-scale data where available.
