Do Government effectiveness and Retirement age, women go together across countries?

Across 49 countries the link before adjusting for anything is r = +0.18, on a scale from -1 (opposite) to +1 (in step). A version that uses only each country's rank gives +0.26.

Does the link hold within countries over time, not just across countries?

Comparing each country only with itself across 1996-2018, and setting aside what happened worldwide in each year, the link is +0.056 (49 countries, 970 country-years). Using year-to-year changes, it is +0.014.

Does Government effectiveness cause Retirement age, women?

This analysis cannot answer that. It shows only that the two go together. A link between two country measures, adjusted or not, does not show that either one changes the other. Country figures also say nothing about individual people.

Government effectiveness vs. Retirement age, women

Holds up after adjusting for income

Across 49 countries, Government effectiveness and Retirement age, women rise and fall together at r = +0.18 (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 = +0.40, q = 0.015, allowing for the many pairs tested).

Comparing countries across the middle half of retirement age, women, 61.3 to 65.4 years, government effectiveness is better by 0.158 points at the top of that range than the bottom. Comparing only countries with similar national income, the gap is 0.241 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.

Every country as a dot

best-fit line line after adjusting

Four ways to measure the link

Method	r	p	Countries
Standard (Pearson), not adjusted	+0.181	0.213	49
By rank (Spearman), not adjusted	+0.260	0.071	49
Standard (Pearson), adjusted for national income	+0.401	0.005	49
By rank (Spearman), adjusted for national income	+0.464	0.001	49

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 49 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: -0.219 (a minus sign means it grew).

How solid is it?

Leaving out one country at a time, r ranges from +0.346 (without JPN) to +0.465 (without IND). 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: IND (+0.064).

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.

	n	r
Europe & Central Asia	32	+0.28

By income third

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

Poorest third	17	+0.20

Richest third	16	+0.55

By largest religious group

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.

	n	r
Christians	38	+0.38

Without outliers (countries far outside the middle half of countries on either measure, by more than one and a half times the width of that middle half): r = +0.372 after dropping 3 countries.

Over time, within countries

Everything above compares countries with each other at one moment. This section compares each country only with itself over 23years. So a link here can’t come from anything about a country that stays the same, such as its history, geography, institutions or culture.

Within countries over time, there is no link that is clearly more than chance (r = +0.056, comparing each country only with itself over the years, and each year only with the same year elsewhere). Whatever the cross-country picture shows, countries whose government effectiveness moved did not tend to see their retirement age, women move with it.

Read with care.

Almost all of the second indicator's variation is between countries, so the within-country estimate rests on a small part of the data.

970 country-years (one country in one year), 49 countries, 1996–2018, about 20 years each on average. Share of the variation that happens within countries over time: 19% for Government effectiveness, 5% for Retirement age, women. 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): +0.056. 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.

The largest value on this curve (+0.13 at lag -5) is higher than the same-year one by 0.07. That gap is not a finding. It is the largest of 21 closely related estimates, and picking the biggest of many tests always makes it look bigger. That is exactly why nothing on this site is ranked or chosen by lag.

How this was computed

Data used: most recent value in 2010-2025; values come from 2010–2024. 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.
