Independent global data desk
The data desk behind WorldStats
An independent atlas of countries, cities, climates, time zones, and global indicators, built and maintained by Jan Krenek.
What WorldStats is for
WorldStats turns public datasets into fast, readable country and city pages. Instead of making you jump between a statistics portal, a weather API, a timezone lookup, and a converter, it keeps the source trail and the practical tools in one place.
How it works
WorldStats pulls public datasets into a structured pipeline: provider API, validation, normalization, storage, and page rendering. Country and city pages read from that same store so search, charts, rankings, and comparison pages stay consistent.
Data quality and labeling
We label indicator and counter quality so you know what you are looking at: official (directly from a primary source), derived (computed from official inputs), estimate (documented approximation), or proxy (stand-in when a direct series is unavailable). Those labels appear on the site alongside source names and years. When series differ between providers, we prefer documented methodology pages over ad-hoc blending — check the relevant methodology article for how a number was produced.
Open data, clearly attributed
We do not invent underlying economic or health statistics. Figures come from the organizations named on each page — World Bank Development Indicators, WHO Global Health Observatory, Open-Meteo (including ERA5-based climate aggregates where applicable), GeoNames for city geography, and REST Countries for country metadata — via their public data or APIs. Our role is to combine, normalize, and present them in one place with consistent navigation and attribution.
Why this is different
WorldStats is built around cross-domain context. A country's population trend, capital city, live weather, climate normals, time zone, rankings, and source notes should connect naturally instead of living in separate single-purpose pages.
Update Cadence
Indicator datasets refresh when their source organizations publish new releases. Live weather and forecast features use documented Open-Meteo sources with caching for reliability. City and country metadata is refreshed through the ingestion pipeline, with source years shown where they matter.
Languages and localization
English is the source language for most editorial copy. Localized pages are generated through the translation pipeline and checked for placeholders, protected source names, scripts, and unchanged English prose.
Independence and monetization
WorldStats may be funded through advertising. Ads do not influence calculations, rankings, source selection, or methodology notes. We do not accept paid placement inside statistical results, and we separate editorial explanations from any future advertising surfaces.
Corrections and feedback
If a number, translation, formula, weather result, or source note looks wrong, send the page URL, the value you saw, and the expected source or correction. Correction reports are reviewed manually and help improve both the page and the underlying pipeline.
