Liberia · Estimated Malaria Incidence (WHO)
172.32024
Unit: cases per 1,000 population at risk per year. Publisher measure: Estimated malaria incidence (per 1000 population at risk).
Estimated new malaria cases per 1,000 population at risk per year. Population at risk means people living where malaria transmission occurs, not the whole national population. WHO adjusts surveillance for care-seeking, reporting and case confirmation and uses prevalence-based modelling where appropriate.
Measurement basis: WHO estimates from adjusted malaria surveillance and prevalence-based models, with a population-at-risk denominator.
Reference-period cadence: annual.
Source update cadence: annual. This does not establish a publication date for an individual reading.
- Estimated new malaria cases per 1,000 population at risk per year. The denominator is people living in areas with malaria transmission, not the whole national population.
- The exact WHO incidence definition identifies supplied bracketed ranges as 95% uncertainty intervals. This applies only to this incidence series; missing endpoints stay absent and no uncertainty level is borrowed for malaria deaths.
- Positive estimates can have publisher display 0. Preserve original numeric precision and genuine source zeros separately; a rounded display is not a less-than threshold or an exact zero.
- Source-country histories have real gaps and different latest years. Keep unreported years unreported; calendar tags do not justify filling them, carrying forward a value or borrowing a legacy reading.
- French Guiana (GUF) and Mayotte (MYT) remain separate raw source geographies excluded from app rows without remapping. Source Date does not establish an official observation publication vintage.
Displayed values are rounded, with extra precision when needed to keep a positive estimate positive. Downloads retain the full numeric estimate and the publisher's original display text separately.
A “<” sign means strictly below the stated number. Numeric readings and uncertainty endpoints keep their own comparison signs. A number without a sign does not establish certainty or an observed outcome.

One row per country, indicator and year, with raw values, source links and reuse notices. Thresholds have an empty numeric value and separate number/operator fields; value_kind distinguishes upper bounds from absent readings.
History and uncertainty
Charts plot numeric readings. Reported upper bounds create gaps; their values, uncertainty endpoints and source notes remain available in the table and downloads.
Reported estimates and uncertainty · 25 rows
Each comparison sign applies to its own reading or uncertainty endpoint. Values retain source precision. “Not reported” identifies an absent reading or uncertainty endpoint in this source capture.
