# Countries

## The source

Countries compares the world country by country, year by year, from the World Bank's Data360
catalog. New workspaces start with it connected.

## Coverage

- Thousands of indicators, such as population, GDP, life expectancy and CO₂
- Every country, plus regional and income groups such as the European Union and low-income countries
- Rankings for one year, and change between two years
- Splits by sex or age where an indicator has them

Years and countries covered vary by indicator. Indicator names can't be guessed, so a search comes
first. One empty answer doesn't prove a country has no data.

## Freshness

Most indicators update once a year. A ranking with no year uses the latest year most countries have
reported. Vistazo holds a copy for up to a day.

## Limits

| Limit | Value |
|---|---|
| Indicators per call | 10 |
| Named years per call | 10 |
