What this is not

Almost every serious error in operational data is a category error rather than an arithmetic one. These are the things this indicator shares a unit with and must never be combined with.

  • A retail per-kilogram price, which carries a margin this figure does not.
  • Maize flour, which is a processed product with its own price.
  • A national average. This is one market in one city.

How current a reading has to be

Current within 21 days, usable within 90 days, measured against the 2026-09-23 build rather than against the time you read this page. A static deployment cannot re-age itself, so the build date is the honest anchor.

Staple prices in the corpus move on harvest, fuel and border cycles measured in weeks, not days. Three weeks is the interval inside which a wholesale bag price still describes today; a quarter is the point past which the season itself has changed.

Readings held (7)

This series has 5 breaks longer than its usable window (2024-03-31 to 2024-09-30, 183 days; 2024-09-30 to 2025-03-31, 182 days; 2025-03-31 to 2025-09-30, 183 days; 2025-09-30 to 2026-03-31, 182 days; 2026-03-31 to 2026-08-25, 147 days). Nothing is known about the indicator during those periods, nothing is interpolated across them, and no line is drawn through them.

What SSIP says about it

  • White maize, 50 kg wholesale bag: 158,000 SSP per 50 kg bag, recorded 2026-08-26 by Ministry of Agriculture Crop Assessment Report, Western Equatoria Cooperative Union Sales Ledger. Past this indicator's 21-day currency window (28 days old as of 2026-09-23); usable with its date shown.
    Rule: Take the most recent dated observation bound to this indicator and classify its age against the indicator's own freshness policy (21 days current, 90 days usable — Staple prices in the corpus move on harvest, fuel and border cycles measured in weeks, not days. Three weeks is the interval inside which a wholesale bag price still describes today; a quarter is the point past which the season itself has changed.).
    Does not establish: That the condition still holds today. This is the most recent reading SSIP holds, not a statement about 2026-09-23. A retail per-kilogram price, which carries a margin this figure does not.
  • The White maize, 50 kg wholesale bag series has 5 breaks longer than its 90-day usable window; the largest runs 183 days from 2024-03-31 to 2024-09-30. Charts of this indicator break the line across those periods rather than drawing through them.
    Rule: Report consecutive published points separated by more than the indicator's usable window as a break in the series. Nothing is interpolated across a break and no line is drawn through one.
    Does not establish: What the indicator did during the break. Nothing is known about that period, and a straight line between two points is a drawing convention rather than a measurement.

What SSIP does not hold

  • Konyo Konyo only. SSIP holds no comparable series for Wau, Malakal, Rumbek, Aweil or Bentiu.
  • The series and the recorded 24-hour change use different survey dates and are not merged into one line.

How to read this

Every figure on this page carries an evidence state — Verified, Operational, Announced, Estimated, Inferred, Disputed, Simulated, Reference or Unavailable — and each state has a stated definition. SSIP does not present an estimate as an observation, and it does not record a missing value as zero.
