## What it measures Healthy life expectancy (HALE) at birth (years) is the canonical measurable outcome used to reconcile catalog item 22. It belongs to **Physical Health and Longevity**, the part of the welfare catalog concerned with survival, avoidable loss of life, and population health over the life course. The exact stored unit is **years**, the geographic presentation is global, the data publisher is **World Health Organization**, and the immutable numerical identity is `WHO-GHO#WHOSIS_000002#Dim1=SEX_BTSX#identity`. The preliminary catalog candidate 22 is reconciled to the exact official series “Healthy life expectancy (HALE) at birth (years)” in years. This is a deliberate canonical correction: the database title names what the values actually measure, while the input wording remains in the reconciliation and audit trail. No hidden proxy label, fallback series, or silently substituted denominator remains. For catalog item 22, the provider definition is: WHO Global Health Observatory indicator Healthy life expectancy (HALE) at birth (years), constrained to Dim1=SEX_BTSX. Country observations are aggregated as a disclosed unweighted comparison; WHO uncertainty intervals are not converted into extra observations. That definition controls the denominator, population, reporting instrument, and statistical meaning. The Russian seed wording does not override it, and provider units and denominators remain unchanged. This Indicator records an observed outcome; it does not assert why that outcome changed. Welfare assessment for item 22 uses `higher_is_better`. Higher observations are treated as better welfare relative to the dated comparative reference. The direction applies to the stored official measure after the disclosed transformation, if any, rather than being inferred from an emotionally positive or negative title. No mathematical transformation is applied before persistence. Keeping title, series identity, unit, scope, transformation, and interpretation together prevents the record from mixing incompatible measurement concepts. ## How it is measured The numerical observations for catalog item 22 were retrieved from **WHO Global Health Observatory** through https://ghoapi.azureedge.net/api/WHOSIS_000002?$filter=TimeDim%20ge%202018%20and%20TimeDim%20le%202025&$format=json. The provider landing page is https://www.who.int/data/gho/data/indicators/indicator-details/GHO/WHOSIS_000002. The research package records the access date, exact dataset and series identifiers, dimension key `Dim1=SEX_BTSX`, unit, provider metadata, transformation, and yearly aggregation label. The bounded Source and Evidence records can therefore reproduce which numbers were used without treating a generic homepage as row-level proof. Measurement provenance for item 22 follows this provider method: The WHO Global Health Observatory supplies economy observations for the exact indicator and dimension tuple. Factrail records a disclosed unweighted annual mean of reporting economies and does not convert uncertainty bounds into observations. 2018 combines 185 reporting economies; 2019 combines 185 reporting economies; 2020 combines 185 reporting economies; 2021 combines 185 reporting economies. The output keeps full numerical precision through NormalLine, deviation, and interpretation calculations. Display clients may round for readability, but the persisted value is not squeezed into a zero-to-one score and is not rounded before calculation. The item 22 NormalLine starts on 2018-01-01 at **67.088167355 years**. 75th percentile of provider-published reporting-economy observations in the selected series and dimensions. The calculation keeps the source unit, dimensions, and transformation fixed and is a comparative reference rather than an invented statutory target. For `zero_is_norm`, the value is exactly zero and is never relaxed because non-zero observations are common. For other interpretation modes, the benchmark is empirical and versioned: a later provider revision can justify a new dated line, but it does not silently rewrite the research package used for this seed. For every item 22 point, `normal_line_value` copies that dated line and `deviation_from_normal` is stored in raw-unit terms as observation minus NormalLine. Arithmetic sign and welfare sign are separate. A positive raw deviation is adverse for `lower_is_better`, favourable for `higher_is_better`, and adverse above zero for `zero_is_norm`. The custom governance score retains its provider scale and uses the public methodology explanation rather than title sentiment. ## What the data shows The complete retained sequence is 2018: 62.9498826463 years; 2019: 63.1129853565 years; 2020: 62.5788587714 years; 2021: 61.8834042784 years. The first observation is **62.9498826463 years in 2018** and the latest is **61.8834042784 years in 2021**. The absolute change is -1.0664783679 years, equivalent to -1.69417054181% of the absolute starting level. The minimum observed value is 61.8834042784 years, and the maximum is 63.1129853565 years. For catalog item 22, the latest observation differs from the NormalLine by **-5.2047630766 years** and is classified as **negative** under `higher_is_better`. That classification is a deterministic comparison, not a causal explanation or editorial verdict. A movement may reflect real change, altered reporting coverage, revised estimates, a changed survey frame, or several of those at once. There are 4 retained item 22 observations in the selected 2018-2025 research window. The retained observations satisfy the minimum temporal rule without interpolation, extrapolation, or forward filling. Missing years are absent observations, not zeroes. The sequence is intentionally irregular when the official source is irregular, because a smooth-looking line created by invented values would be methodologically false. The displayed global item 22 sequence has one consistent numerical identity: `WHO-GHO#WHOSIS_000002#Dim1=SEX_BTSX#identity`. No second source series is spliced into a gap, no latest value is copied into a missing year, and no country-only observation is relabelled as a World value. If the source later adds or revises an observation, the update must arrive as a new reviewed research package with its own checksum and audit record. ## Drivers and interpretation Healthy life expectancy (HALE) at birth (years) can be associated with economic, institutional, demographic, environmental, behavioural, or service-delivery mechanisms, but this seed does not create a DriverIndicatorImpact from topical resemblance. A defensible graph edge requires an existing Driver, direction, strength, lag, confidence, and Source/Evidence that supports the mechanism. The outcome series alone cannot establish that causal chain. For item 22, importance weight **0.8500000000000001** is generated by `indicator-importance-rubric-v1`. Its five committed components are directness 0.85, population reach 0.8, persistence 0.8, effect on human capabilities 0.9, and overlap control 0.85. The formula weights them 0.35, 0.25, 0.20, 0.15, and 0.05, then rounds to the nearest 0.05. The value is deterministic and reproducible; it is not an intuitive score assigned while drafting prose. ## Limitations and caveats The 2018-2021 sequence for item 22 is too short for strong causal or structural claims. Cross-economy comparability can be affected by institutional definitions, survey coverage, modelled estimates, missing observations, classification practices, revisions, and unequal statistical capacity. A global aggregate or unweighted reporting-economy mean can also conceal distributional extremes and should not be used as an individual-level estimate. The item 22 NormalLine is a transparent comparative reference, not a claim that every jurisdiction has the same legal target or feasible frontier. The source may revise both historical points and metadata. Any later refresh must preserve the earlier Source, Evidence, checksum, and audit trail; it must not mutate the meaning of an already reviewed series identity.
How to read it
Higher is better — readings above the norm count as better.
Measured value over time. Its norm (67.1 years) is far off this scale, so the series stays worse than norm throughout — the deviation badge shows the gap.
Each driver linked to this indicator, strongest pull first, on the same timeline above. Markers are the facts that moved that driver. These are modelled influences — treat them as correlational unless a documented causal edge is shown.
No drivers are linked to this indicator yet.
