Each point is a country. All markers are equal in size.Data source: World Bank WDI / ADG local snapshotMethod: No trend or causal model is fitted. Nominal GDP is not purchasing-power parity.

The zero line separates rising from falling annual inflation rates.Data source: World Bank WDI / ADG local snapshotMethod: A falling inflation rate does not necessarily mean falling prices.

Left and right bars use the same magnitude scale for each age group.Data source: ADG deterministic test fixture (not observed data)Method: Illustrative counts are not demographic observations. Labels define both sides.

Each group uses its ten annual observations. The center marks the median.Data source: World Bank WDI / ADG local snapshotMethod: Whiskers use 1.5 times the IQR. Outliers are observations, not errors.

Read the two years within each country, then compare countries.Data source: World Bank WDI / ADG local snapshotMethod: Rates are annual changes, not price levels. Compare like periods.

Each pair links the same country. Position gives the rate in each year.Data source: World Bank WDI / ADG local snapshotMethod: The line does not describe the path between the two observations.

Length or position shows the rate. All countries share a zero baseline.Data source: World Bank WDI / ADG local snapshotMethod: The selection is not the whole region. A country rate is not a regional average.

Each cell compares two variables across the same country observations.Data source: World Bank WDI / ADG local snapshotMethod: Association is not causation. Outliers and scale choices can matter.

Length or position shows the rate. All countries share a zero baseline.Data source: World Bank WDI / ADG local snapshotMethod: The selection is not the whole region. A country rate is not a regional average.

Each axis runs from the shown minimum to the shown maximum.Data source: World Bank WDI / ADG local snapshotMethod: Larger is not always better. Polygon area is not a score. Use a table for exact values.
