E₁: Food — 7-day recall → × 30/7 to monthly — from level_05/06 (§1.5 Cat I)

wmean per bucket (1..6,7+,8+) = Σ(mpce×MULT)/Σ(MULT) — AppxB 3.6 ratio R̂=Ŷ/X̂.

Processing & manipulations — full transparency

Every step after SQL. No hidden transforms.

WHAT WE DO — step by step

1 Python: bucket P1→cat, for each cat & sector compute weighted mean with raw MULT (uncalibrated).
2 Rural/Urban split is Sector 1/2 as surveyed, no Census re-weight.

WHAT WE DO NOT DO — report does, we intentionally skip

Weight calibration N/n × D1 × H/h → Census 2011 — AppxB pB13 4.0 & B9–B10. Source: censusindia.gov.in projected Sector×State×SSS.
Free-item imputation (KDE) §2.3 p15–16 — modal Sector×State via Gaussian KDE, 061–075 + PDS 7 + durables 600–623. Would lift to Sec II 4247 / 7078.
CPI deflation Table 3.3 note(ii) p25 — CPI(R)/CPI(U) to 2011-12. Source: mospi.gov.in / RBI DBIE.

Hence raw ~2793 / 5146 vs published 4122 / 6996 is documented, not hidden. No outlier trimming, no re-weight; filters only HOUSEHOLD_SIZE > 0, MPCE > 0 and P1 & P2 & P3 all present (§2.2.0 — incomplete visits dropped).

Amber rows = external inputs not in Parquet — add them to go from raw ~2793/5146 to published 4122/6996 (Sec I) and 4247/7078 (Sec II).
