About the Tribal Area
State-recognized Indigenous descent group in Louisiana. Because there is no single federal reservation footprint in the Census tribal-area geography, broadband planning is typically tied to dispersed households, county road access, and nearby regional infrastructure.
Tribal Area Description
Grand Caillou/Dulac is a State-designated tribal statistical area (SDTSA), a Census statistical geography identified for a state-recognized tribe or community rather than a federally recognized reservation land base. Boundary records for Grand Caillou/Dulac show about 67.9 square miles (43,457 acres) for this state-designated statistical area, centered near latitude 29.4443837 and longitude -90.6447248. FCC BDC provider counts are not fully populated for this code in the local dataset, so current service inventory should be validated before relying on deployment comparisons.
