Enumeration total: 32,563 across 11 clans and 371 towns/villages. Note: several "clans" in this district (Watco, Kpanada, Water Tower, Gonnigar, Tarrbarr, Own Your Own) correspond to Buchanan peri-urban community settlements rather than traditional rural clans. Official LISGIS district total: 62,883.

5 Largest Towns:

Neekreen's rubber plantation economy links it to Buchanan's port infrastructure, through which Grand Bassa's rubber exports are processed. Neekreen town serves as the district's administrative hub. The 96.2% population increase between 2008 and 2022, the fastest in the county, reflects both natural growth and the resettlement of war-displaced communities. Several large Buchanan peri-urban communities fall administratively within Neekreen, accounting for the district's urban character alongside its plantation zones.

Enumeration total: 49,525 across 14 clans and 341 towns/villages. Official LISGIS district total: 62,421.

5 Largest Towns:

Buchanan City was named after Thomas Buchanan, the first Governor of the Commonwealth of Liberia under the ACS (1839). The LAMCO iron ore company constructed Buchanan's port to export iron ore from the Nimba mountains via rail. The civil war destroyed port infrastructure, the LAMCO railway, and much of the township's built environment, all progressively rehabilitated since 2003. The "Wee" sub-designation refers to inland hinterland communities beyond Buchanan itself; the Liberian Agriculture Company (LAC) plantation is a major economic presence, reflected in the enumeration data as the LAC Plantation clan.

Enumeration total: 30,454 across 10 clans and 298 towns/villages. Official LISGIS district total: 41,162.

District 4 (Kpaoegbarn) occupies a strategic interior position at the intersection of three county borders. Its predominantly rural character is defined by subsistence agriculture, forest resources, and small-scale mining. The district's higher male proportion (52.5%) likely reflects patterns of labour migration into extractive activities in the border zones. Significant forest cover contributes to Grand Bassa's vegetation resource base, which includes ironwood and mahogany among commercially valuable species. The LAC Plantation clan reflects the presence of a Liberia Agriculture Company plantation unit in the district.

Enumeration total: 34,893 across 15 settlement units and 15 enumeration entries. Note: Commonwealth District's enumeration data consists entirely of Buchanan City neighbourhood and community units, not traditional rural clans. The column header has been adjusted accordingly. This reflects Commonwealth District's urban character as the core of Buchanan City. Official LISGIS district total: 35,740.

5 Largest Communities:

Edina, located within Commonwealth District, is one of Liberia's oldest Americo-Liberian settlements, founded in the 1830s partly by emigrants sponsored by Scottish organisations; its name references Edinburgh. Commonwealth District's female majority and coastal location are associated with fishing communities, coastal settlement, and trading heritage. The district's Buchanan City core gives it a uniquely urban demographic profile compared to all other Grand Bassa administrative districts.

Enumeration total: 25,722 across 11 clans and 404 towns/villages, the most towns/villages of any Grand Bassa district. Official LISGIS district total: 32,565.

5 Largest Towns:

Glarkon District's location along the Bong and Margibi county borders positions it as a cross-county agricultural and commercial corridor. The St. John River's tributaries, including the Farmington, Merchin, and New Cess rivers, provide watershed resources for communities here. Subsistence farming (rice, cassava, palm products) forms the primary livelihood, supplemented by rubber cultivation in smallholder plots. The Glarkon designation reflects a local Bassa toponym.

Enumeration total: 24,612 across 10 clans and 408 towns/villages. Official LISGIS district total: 30,223.

5 Largest Towns:

District 1 (Dianblae) was one of Grand Bassa's four original administrative districts before the 2003 restructuring. Its eastern location along the Margibi County boundary means communities here are influenced by both Grand Bassa's Bassa-dominated culture and Margibi's more diverse presence. The Farmington River supports agriculture and seasonal fishing. Subsistence farming, comprising rice, cassava, plantains, and palm products, forms the primary livelihood, with some communities engaged in rubber tapping. Electoral District 1 Representative (2023): Isaac G. Bannie (MPC).

Enumeration total: 10,010 across 10 clans/wards and 239 towns/villages. Note: St. John River City contains both traditional rural clans and city ward designations (Hartford, Beulor, Famazette, Fortsville, Bexley). Official LISGIS district total: 14,273.

5 Largest Towns:

St. John River City's coastal estuary location historically made it a node for river and Atlantic coastal trade, connecting interior communities along the St. John River system to Atlantic shipping routes. The coexistence of traditional clan units and formal city ward designations in the enumeration data reflects the settlement's dual character as both a historic city and a predominantly rural-coastal community. The district falls within Electoral District 5.

Enumeration total: 13,666 across 3 clans and 156 towns/villages, the fewest clans of any Grand Bassa district. Owensgrove is one of only three Grand Bassa districts where females outnumber males in the enumeration data (alongside Neekreen and Commonwealth). Official LISGIS district estimated total: ~14,422 (derived arithmetically; not independently published in Table B1).

5 Largest Towns:

Owensgrove District's relatively modest population, consistent between 2008 (13,687) and estimated 2022 (~14,422), suggests slow resettlement since the civil war period. The district's female-majority enumeration profile (7,017 F vs 6,649 M) is notable. The district's name may derive from early Americo-Liberian settlement history. Electoral District 5 Representative (2023): Thomas A. Goshua II (CPP).
