Property rights vs. Regime type
Holds up after adjusting for income
Across 168 countries, Property rights and Regime type rise and fall together at r = +0.62 (on a scale from −1 to +1, where 0 means no link). It holds up almost unchanged when only countries with similar income (GDP per person) are compared (r = +0.51, q = 0.016, allowing for the many pairs tested).
Comparing countries across the middle half of regime type, 1 to 2 points, property rights is better by 0.125 points at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 0.102 points.

How to read these.r runs from −1 (one goes up as the other goes down) to +1 (they rise together), and 0 means no link. Adjusting for national income means comparing countries with the same GDP per person, so differences in wealth can’t explain the link. Income is used in percentage terms, since an extra $1,000 means more to a poor country than to a rich one. p is how likely a link this strong would be if there were really none. Below 0.05 means it is unlikely to be chance. Very small values are written in short form: 1.1e-32 means a decimal point followed by 31 zeros and then 11, so very close to zero. The likely range is where the true figure probably lies, and a range that crosses zero means the link could easily be chance. Countries in the same region tend to resemble each other, so the third figure allows for that, which gives a fairer p. The standard error is the typical size of the error in r. Finally, testing this many pairs means some will look strong by luck alone. A q below 0.05 means this link is unlikely to be one of those.

“Link with income” is how closely each measure tracks GDP per person across countries, from −1 to +1.

Four ways to measure the link
| Method | r | p | Countries |
|---|---|---|---|
| Standard (Pearson), not adjusted | +0.624 | 1.8e-19 | 168 |
| By rank (Spearman), not adjusted | +0.667 | 5.2e-23 | 168 |
| Standard (Pearson), adjusted for national income | +0.510 | 1.9e-12 | 168 |
| By rank (Spearman), adjusted for national income | +0.540 | 4.8e-14 | 168 |
The rank version uses only each country’s place in line, from lowest to highest, so a few extreme countries count for less. The adjusted and unadjusted versions use the same 168 countries: those that report both measures and GDP per person. So the gap between them comes from the adjustment, not from a change in which countries are counted. Drop in the size of r after adjusting: +0.114 (a minus sign means it grew).
How solid is it?
Leaving out one country at a time, r ranges from +0.476 (without QAT) to +0.528 (without BGD). The bar above shows that range on a scale from −1 to +1, with the solid line at the full result. The single country that moves r most: QAT (-0.034).
Within each region
Countries are not separate, unrelated cases, and neighbors share a lot. A link that holds inside each region is far more believable than one that shows up only when comparing regions.

If the link shows up only in the richest third of countries, it is a feature of rich countries, not a general pattern.

Countries grouped by a label they share, such as main religion, rather than by a number. Groups of fewer than twelve countries are not shown. These groups differ in income, region and history all at once. So a gap between them is a place to start asking questions, not an answer.

Two series, one country
Both measures over the years for one country you pick. The two charts are stacked so they share only the years along the bottom.

Over time, within countries
Everything above compares countries with each other at one moment. This section compares each country only with itself over 36years. So a link here can’t come from anything about a country that stays the same, such as its history, geography, institutions or culture.
The link also shows up within countries over time (r = +0.313). It holds even when looking only at changes from one year to the next (r = +0.136). This is the strongest kind of evidence available here: it holds when each country is compared only with itself, and it is not just a product of shared trends.

6,238 country-years (one country in one year), 175 countries, 1990–2025, about 36 years each on average. Share of the variation that happens within countries over time: 18% for Property rights, 11% for Regime type. The margins of error allow for each country appearing many times, and for each year’s value being close to the year before.
Year-to-year changes are a cautious test, not a final answer. Looking only at changes from one year to the next removes each country’s own trends. But it also makes measurement mistakes louder, which pulls the results toward zero. A near-zero result here is weak evidence of no link, not proof.
With one measure years behind the other
Same year (lag 0): +0.313. A peak away from zero does not show which comes first. These series change slowly — this year’s value is close to last year’s. That makes the curve smooth and nearly symmetric, whatever produced the data. Even a sharp peak at one lag (a gap of some years) would not prove that one measure changes the other.

How far people have the right to own, buy, inherit and sell private property, including land, from 0 (virtually no one) to 1 (virtually everyone). It combines V-Dem's expert ratings for men and for women. Limits can come from the law, from the state failing to enforce it, or from custom and religion. It is about the right to property, not how much property people actually own.

Four ranked categories, not a scale. It is the only such measure on this site. A closed autocracy holds no multiparty elections for its leader. An electoral autocracy holds them, but they are neither free nor fair. An electoral democracy clears that bar. A liberal democracy also has independent courts and protected personal freedoms. The four steps are not equal distances apart. So read the rank-based link, which uses only the order, rather than the ordinary one. Both are shown. The categories are set by cut-off points on the V-Dem indices already on this site. That is why its pairs with them are flagged as built from the same numbers. It is also why it is kept out of the governance score: a grouping of those indices averaged back in beside them would count each twice. Our World in Data extends the categories back to territories before independence. This site starts at 1960, and its single-year snapshot at 2010, so that extension reaches nothing shown here.
How this was computed
Data used: most recent value in 2010-2025; values come from 2025. To adjust for income, each measure is first predicted from GDP per person (in percentage terms, on a log scale) with a straight-line fit. Only what is left over is then compared. This is called a partial correlation. The line is drawn the standard way (ordinary least squares), which picks the line that comes closest to all the countries at once. The error margins allow for countries in the same region resembling each other, using 7 World Bank regions. The q-value corrects for testing all 17,292 pairs at once, using the Benjamini–Hochberg method. Underlying data last updated V-Dem v16; V-Party v2.

This page shows that two measures go together. It does not show that Property rights changes Regime type, or the reverse. These figures also describe countries, not individual people. See the ecological fallacy.
