SOURCES & METHODOLOGY
Data you can verify.
Each observation retains its country, indicator, year, value, source and retrieval time. Data is prepared on the server. A source failure preserves the last valid snapshot and its date.

Reading values and aggregates
“Latest available” retains each country’s actual observation year. Select a specific year to compare the same period. Missing years remain empty: no interpolation or carrying observations forward. Ranks and regional gaps compare values from the same year only.
Volumes (population, GDP, aid) are summed; ratios are weighted by same-year population or GDP. Fertility, inflation, arable land and account ownership use the median where a suitable denominator is unavailable. The region panel offers the median or this aggregate. Contributor counts are shown. A partial sum is not the total for Africa.
The legend uses five quantile classes. Equal values stay in the same class. The logarithmic scale excludes zero and negative values. Bivariate views cross three classes per indicator, for countries with matching observation years. Similar countries use z-score distance with at least 70% available indicators and matching years for each pair.
Projections
World Bank source 40 publishes UN WPP 2024 estimates and projections. Years after 2024 are labelled “projection” and hatched, even if they precede the current year. “Latest available” excludes projected observations; select 2030 or 2050 to view them.
Crises and additional sources
The atlas layer combines GDACS, USGS and NASA EONET. Active-alert counts use GDACS: events starting in the last 30 days with an end date confirming they remain active. An unknown end date is not interpreted as an active alert. Server responses are cached for 15 minutes. Counts represent alerts, not casualties or needs. Detailed monitoring retains existing GDACS, USGS, NASA EONET and HDX HAPI connectors with their respective availability.

Boundaries and small states
Simplified geometry comes from Natural Earth (public domain). Boundaries are indicative and do not imply endorsement. Western Sahara is shown with gray hatching and is not selectable. Five small island states have enlarged markers; hexagons represent all 54 countries with equal area.
