Labour Force Survey Coverage Index

Each country gets three sub-scores from 0 to 100 — coverage, frequency & regularity and recency — computed from its ILOSTAT record, counting only observations that come from a household survey (labour force surveys and other household surveys with a labour module; administrative and establishment sources and population censuses are excluded). The overall score is the weighted average of the three, using the weights on the left. Weights are normalised, so only their relative sizes matter.

The share of the key indicators (weighted by importance, with headline indicators counting more) for which the country has at least one qualifying household-survey datapoint within the coverage window.

The average of two parts: a periodicity score (monthly data scores highest, then quarterly, then annual, then irregular) based on the fastest cadence the country sustains for its headline indicators; and a regularity score — the share of recent years in which headline data was actually produced, which penalises long gaps between surveys.

Based on the age of the most recent qualifying datapoint across the key indicators, decaying linearly from full marks for current-year data down to zero once the newest data passes the configured age limit.

ILOSTAT re-publishes national data with a processing lag, so a country's newest figures often sit on its national statistics office (NSO) site before they reach ILOSTAT. For tracked countries we record the NSO's latest published period in a small registry (pipeline/nso_releases.json), and the tool lists every period between ILOSTAT's latest and the NSO's latest as pending — shown as a badge in the table and in detail (with a source link) in the country panel. Countries not in the registry show no badge; it doesn't mean they have nothing pending, only that we aren't tracking their NSO yet.
