Economy free of state ownership vs. Electoral democracy
Holds up after adjusting for income
Across 168 countries, Economy free of state ownership and Electoral democracy rise and fall together at r = +0.65 (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 = +0.66, q = 0.0082, allowing for the many pairs tested).
Comparing countries across the middle half of electoral democracy, 0.259 to 0.739 points, economy free of state ownership is 1.23 points higher at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 1.38 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 | +0.654 | 6.9e-22 | 168 |
| By rank (Spearman), not adjusted | +0.629 | 7.2e-20 | 168 |
| Standard (Pearson), adjusted for national income | +0.657 | 4.9e-22 | 168 |
| By rank (Spearman), adjusted for national income | +0.613 | 1.3e-18 | 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: -0.003 (a minus sign means it grew).
How solid is it?
Leaving out one country at a time, r ranges from +0.644 (without QAT) to +0.669 (without TLS). 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 (-0.014).
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.

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 = +0.298). It holds even when looking only at changes from one year to the next (r = +0.128). 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.

6,252 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: 12% for Economy free of state ownership, 15% for Electoral democracy. 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): +0.298. 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.

Economy free of state ownership
State ownership of the economy (higher = less owned by the state)
V-Dem Institute, University of Gothenburg · CC BY-SA 4.0 · updated annual (V-Dem); V-Party per election, to 2019
Does the state own or directly control the important parts of the economy? Experts answer from 0 ("virtually all valuable capital belongs to the state") to 4 ("very little valuable capital belongs to the state"), and V-Dem turns their answers into a score that runs from about -4 to +4. So a low score means a mostly state-run economy, as in North Korea or Eritrea, and a high score a mostly private one. It is about ownership and control, not taxes or welfare: a country can tax and spend a great deal while the state owns almost nothing. Today it lines up only weakly with how rich a country is. Oil states such as Saudi Arabia, Qatar and Kuwait are rich while the state owns much of the economy, and some of the poorest countries, such as Somalia, Haiti and the Central African Republic, have little state ownership. The link with income was stronger in the 1960s and has weakened every decade since. Within Europe and Central Asia, where former communist countries sold off state firms, it is still strong. No "better" direction is set: how much the state should own is a political question.
Electoral democracy
Electoral democracy index (polyarchy)
V-Dem Institute, University of Gothenburg · via Our World in Data · CC BY-SA 4.0 · updated annual
Based on political scientist Robert Dahl's idea of "polyarchy": are leaders chosen in free and fair elections, with freedom of speech, freedom to form groups, and the vote for nearly all adults? It is the base index that most other V-Dem measures are built on.
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.
