Chittagong Hill TractsBangladesh

A region best understood in layers.

Follow the ridges and rivers. Meet distinct peoples on their own terms. Trace how land, law, movement, conflict, peace, and public services continue to shape one another.

Definition- and date-specific figures. Sources MS0001 and MS0006–MS0008.

Layered forested ridges descending toward a broad waterway, with small distant settlements and boats under monsoon mist — Terrain is not background here. Water, roads, boundaries, and public decisions influence who is connected, exposed, or displaced.

Orient yourself

Three districts. Twenty-six current upazilas.

The present administrative unit is one useful frame, but watersheds, customary geographies, forests, historical borders, and everyday travel do not follow the same lines.

Schematic orientation only. Open the accessible place list for sourced profiles.

Start with the region

Different boundaries answer different questions.

Choose a district to see its upazila count and a cautious orientation. District averages never describe every community or settlement.

Choose a question, not a silo

Eight ways into one connected region.

Each route starts with a clear explanation, then lets you inspect dates, definitions, sources, disputes, and gaps.

A shared roadside landing with market baskets, school materials, water containers, and public transport against distant ridges — Everyday routes connect markets, schools, water, care, and public decisions. Editorial visual, generated.

Trust is part of the interface

What is known, what is disputed, and what has not been found stay visibly different.

Every consequential statement should carry its period, geography, definition, source, status, limitation, review date, and correction route.

Reviewed baseline

Three districts and 26 current upazilas

Administrative counts are date-specific. Older 25-upazila sources predate Guimara’s current inclusion.

Calculated with caution

Population residuals are not identity counts

Total minus the statutory ethnic-population category is a calculated residual, not an official Bengali total.

Preserved disagreement

Accord totals are not one score

Formal action, staffing, operation, output, and remedy must be evaluated separately.

Open evidence gap

Absence from the reviewed record is not proof of absence

Pages state what records were not located and what would materially change the finding.
