Government consumption vs. Interpersonal trust

Holds up after adjusting for income

Across 102 countries, Government consumption and Interpersonal trust rise and fall together at r = +0.43 (on a scale from −1 to +1, where 0 means no link). Comparing only countries with similar income (GDP per person) shrinks it to +0.27 (q = 0.0014, allowing for the many pairs tested). Much of the first figure is that both measures rise with national income, but a weak positive link remains. Caution: direction is not consistent across regions.

Comparing countries across the middle half of interpersonal trust, 12.8% to 32.6% of respondents, government consumption is 3.02% of GDP higher at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 2.08% of GDP.

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.

Four ways to measure the link

MethodrpCountries
Standard (Pearson), not adjusted+0.4316.1e-6102
By rank (Spearman), not adjusted+0.4423.3e-6102
Standard (Pearson), adjusted for national income+0.2650.007102
By rank (Spearman), adjusted for national income+0.1950.050102

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 102 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: +0.166 (a minus sign means it grew).

How solid is it?

Leaving out one country at a time, r ranges from +0.240 (without FIN) to +0.303 (without LBY). 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: LBY (+0.038).

Fragile: this link may not hold up.

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.

Over time, within countries

Everything above compares countries with each other at one moment. This section compares each country only with itself over 0years. So a link here can’t come from anything about a country that stays the same, such as its history, geography, institutions or culture.

Not enough history inside each country to look at this over time. That needs countries measured for several years in a row, and at least one of these measures is measured too rarely.

Government consumption

General government final consumption expenditure (% of GDP)

World Bank · CC BY 4.0 · updated quarterly

What government buys directly, as a share of the economy: wages, defence, and the running of schools and hospitals. It is the widely reported half of government size. Payments such as pensions and benefits are handed out, not spent on goods and services, so they are not in here. That understates government in the countries with the largest welfare systems. Government expense covers those, but for fewer countries. Compared with income per person, this answers the question the per-person dollar figure cannot. Rich countries spend far more per person because they have far more per person. Whether their governments are a larger share of what there is needs a share of GDP, not an amount per person. No "better" direction is set: a bigger or smaller government is a political question, not a better or worse one.

Interpersonal trust

Share agreeing that most people can be trusted

World Values Survey Association and European Values Study · via Our World in Data · Free for non-commercial use with attribution · updated irregular (survey waves, roughly every 5 years)

The share who answer "most people can be trusted" rather than "you can't be too careful". Trust in other people is the classic measure of social ties (social capital). It is only loosely linked to national income. That makes it one of the few measures here where adjusting for GDP is a real test, not a foregone result. The survey runs in waves, not every year. So data for each country are sparse and uneven, and two readings for a country may be five or more years apart.

How this was computed

Data used: most recent value in 2010-2025; values come from 2010–2025. 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 12,497 pairs at once, using the Benjamini–Hochberg method. Underlying data last updated DYB 2024.

This page shows that two measures go together. It does not show that Government consumption changes Interpersonal trust, or the reverse. These figures also describe countries, not individual people. See the ecological fallacy.
