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 2018–2024.
Jurisdictions (N)Number of jurisdictions in the 2024 snapshot.
17.9%
Mean Rev/GDPCross-country mean of total tax revenue as a share of GDP.
21.9%
Mean PIT/RevCross-country mean of PIT revenue as a share of total tax revenue.
Total GDP
Bubble sizeBubble area is proportional to total GDP (USD).
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 101 jurisdictions reporting in every year
from 2018 to 2024, so
each bubble can be followed through time. The legend counts, KPI tiles and
the Statistics view use the full FY2024 snapshot (136 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.
