Is 70% Good Enough? RDA Compliance Threshold Critique

The district nutrition dashboard reports 82% RDA compliance for energy intake. But the compliance definition uses a 70%-of-RDA threshold instead of the full RDA. The analyst must determine whether this threshold hides the true scale of undernutrition — and what the real compliance number should be.

## Overview
The district nutrition dashboard reports 82% RDA compliance for energy intake. But the compliance definition uses a 70%-of-RDA threshold instead of the full RDA. The analyst must determine whether this threshold hides the true scale of undernutrition — and what the real compliance number should be.

## Case Details

Function Focus: Metric threshold sensitivity analysis, compliance definition critique, hidden-gap quantification, communicating methodological bias to policymakers

Scenario:
The ICDS district dashboard shows "82% of households meet RDA for energy (calories)." The District Magistrate is satisfied. But a visiting researcher from NIN notices the fine print: "Compliance defined as intake ≥ 70% of RDA." She asks the analyst: what if we used 100% of RDA instead? The analyst runs the numbers and finds compliance drops sharply. Worse, a large group of households falls in the 70–99% band — technically "compliant" under current rules but still undernourished. She must quantify the hidden gap and recommend whether the threshold should change — before the next review meeting.

Dataset Structure:
- 5 nutrient groups with RDA values and current average intake
- Compliance at 70%-of-RDA threshold vs 100%-of-RDA threshold
- Household distribution across intake bands for energy (calories)
- Number of households in the "hidden gap" (70–99% of RDA)

Tasks:
1. For each of the 5 nutrient groups, compute the compliance rate under the current threshold (≥ 70% of RDA) and under the full threshold (≥ 100% of RDA) — present both in a comparison table
2. Using the household distribution for energy, count how many households fall into the hidden gap (between 70% and 99% of RDA) — express this as a percentage of all households and as a percentage of currently-reported "compliant" households
3. Identify which single nutrient group has the largest absolute drop in compliance when switching from 70% to 100% threshold — calculate the drop and state what this tells you about that nutrient's intake pattern
4. Recommend a threshold policy: should the district switch to 100% of RDA, keep 70%, or report both? Justify your recommendation with specific numbers from your analysis and state the communication risk of each option
5. Only after submitting your manual analysis, re-run the compliance calculations in a spreadsheet or AI tool and note any discrepancy

Expected Output:
A threshold analysis memo containing: (a) compliance comparison table for all 5 nutrients at both thresholds, (b) hidden-gap quantification for energy with explicit counts, (c) identification of the nutrient with the largest compliance drop and why, (d) a threshold policy recommendation with justification, and (e) a round-trip discrepancy note.

Evaluation Criteria:
Correct computation of compliance rates at both thresholds, accurate hidden-gap quantification, correct identification of the nutrient with the largest compliance drop, a well-reasoned threshold recommendation that considers both technical accuracy and communication risk, and honest discrepancy reporting.

## Data Sources

RDA and Current Average Intake (per adult equivalent per day):
| Nutrient | RDA | Current Avg Intake | % of RDA (avg) |
|---|---|---|---|
| Energy (kcal) | 2,100 | 1,680 | 80% |
| Protein (g) | 60 | 42 | 70% |
| Iron (mg) | 17 | 12 | 71% |
| Vitamin A (mcg RAE) | 600 | 420 | 70% |
| Calcium (mg) | 800 | 520 | 65% |

Household Distribution for Energy (kcal/day) — 1,000 households surveyed:
| Intake Band (kcal) | % of RDA | Households |
|---|---|---|
| 0 – 1,049 | 0–49% | 45 |
| 1,050 – 1,469 | 50–69% | 135 |
| 1,470 – 1,889 | 70–89% | 280 |
| 1,890 – 2,099 | 90–99% | 240 |
| 2,100 – 2,519 | 100–119% | 200 |
| 2,520+ | 120%+ | 100 |

Current Dashboard Definition:
- Compliant = intake ≥ 70% of RDA (i.e., ≥ 1,470 kcal for energy)
- Dashboard headline: "82% of households are RDA-compliant for energy"

Context:
- District Magistrate reviews this dashboard quarterly
- Supplementary nutrition budget: ₹1.8 crore
- NIN researcher's note: "Many districts use 70% thresholds. This systematically undercounts undernutrition by 10–25 percentage points."
