The two WDI series below are republished without changing their observations. WDI describes its growth series as derived from total population. Younivi selects the 25 displayed economies, ranks and formats the values, and computes the displayed difference from the previous year; those presentation calculations are not new source observations.

Underlying data providers
The World Bank indicator metadata credits the UN Population Division (World Population Prospects), national statistical offices, Eurostat (Demographic Statistics), and the UN Statistics Division (Population and Vital Statistics Report). The World Bank publishes the WDI series; these providers contribute underlying population data. The Eurostat link is a general demographic reference, not an exact match for a WDI observation or method.

How to read a missing value
Where the World Bank does not report an economy — Taiwan is the case on this site — the country page shows the series label, the words Not tracked, and a note saying why. Not tracked means exactly that: the source does not publish the series, so we do not publish it either. It is never estimated, borrowed from another economy, or filled from a national source.
Checking a figure
How to check any number here: open the source line under the table — it links to the World Bank indicator page — and match the year and the value. For a reviewed data update, the per-desk files are normalised from recorded indicator responses, so a figure can be traced to the source snapshot used for that update.
Attribution

The data are used under CC BY 4.0; the licence links appear above and under each series. Younivi selects, ranks, formats and calculates displayed year-to-year differences from the sourced values. This site and its calculations are not endorsed by the World Bank or the underlying providers.
If you share or sublicense these data, retain the World Bank and known-provider acknowledgement and require downstream recipients to do the same. See the World Bank data terms for this condition.
Updates and corrections
The Bank can revise estimates as new censuses, registers and surveys arrive. This site adopts a new source release only after a separate reviewed data update and site build. If a figure here disagrees with the World Bank's table, write to contact@younivi.com and we will check the source snapshot and published page.
Every figure shows its observation year. A reviewed data update retrieves the two WDI series and regenerates the desk files; the static site build reads those files without fetching new observations. Changes are checked before publication.
