Details

Components are organized as durables (1-41), nondurables (42-91), services (92-177), and one NPISH aggregate (178). The 2009 tech notes (Dolmas, "Trimmed Mean PCE Inflation," updated 2022-12-23) list 178 components; BEA combined two of them - Tenant-Occupied Stationary Homes and Tenant Landlord Durables - into a single line of Table 2.4.4U (IA000629) when the disaggregated series stopped in December 2001. The mapping reflects that combination, yielding 177 rows; dallas_idx runs 1..178 with 94 omitted (93 holds the merged item).
