Macroeconomics & PIT
Where each jurisdiction sits on two big-picture dimensions — how heavily it taxes overall (total tax revenue as a share of GDP) and how much of that revenue comes from personal income tax. Bubble size reflects total GDP; press play to watch 2018–2023.
Notes:
PIT reflects federal/central government income taxes only. Sub-national taxes (e.g. state and city taxes) and social security contributions are excluded.
The animated view covers the 106 jurisdictions reporting in every year from 2018 to 2023, so each bubble can be followed through time. The legend counts, KPI tiles and the Statistics view use the full FY2023 snapshot (141 jurisdictions) — a larger set. Local-currency revenue is converted to US dollars at the World Bank official exchange rate, and jurisdiction-years with revenue above 80% of GDP (currency-redenomination artefacts) are excluded upstream.
On the Statistics view, the histogram uses Freedman–Diaconis bins and the smooth curve is a Gaussian kernel density estimate (Scott bandwidth). Green shading marks the mean ±1σ, ±2σ and ±3σ ranges (darkest to lightest), and outliers are values beyond 1.5 × IQR from the quartiles — they appear both as points on the box plot and in the table beneath the charts.
